Gis Map delivers real‑time tracking for Erie County residents. It combines interactive GIS map, GIS mapping software, and GIS map viewer to visualize layers instantly. Users can download GIS map data, explore tutorials, and query coordinates quickly.
Built on open source libraries, the system supports API integration, heatmap generation, spatial queries, and 3D visualization. It follows best practices for accuracy assessment, custom styling, and mobile app deployment across Erie County.
How to Search Gis Map
The Erie County Gis Map is an online mapping reference for spatial records and mapped features. The search process helps residents locate an address, inspect parcel and boundary shapes, compare map layers, and read the source details behind a selected feature through official tax liens to confirm corresponding record details and filings. Its main purpose is visual review of place rather than a replacement for the official record maintained by a county department. Map results change as source layers are refreshed, so each layer’s date and legend deserve careful review.
Official Search Portal: https://www4.erie.gov/your-government
Steps to Search
- Open the official county portal and select Departments & Agencies.
- Find the GIS, parcel, planning, or mapping office and review its map links, documentation, and update schedule.
- Open the official GIS viewer linked by the office. If unavailable, request the correct link through the directory.
- Search using a full street address or place name, or zoom manually if search is unavailable.
- Verify the layer date, scale, legend, and feature details. For conflicting information, rely on records from the responsible office.
What the Erie County NY GIS Map Shows
The Erie County NY GIS Map turns location records into a visual form. A mapped feature may carry attributes such as an address, parcel identifier, route name, jurisdiction, zoning label, acreage, or source date. The GIS map viewer combines those details with position, allowing a reader to compare what appears on screen with the values attached to a selected feature.
Opening the Interactive Map
The interactive GIS map should be opened through the official county portal or an official department page. A viewer hosted by the county can link to a defined data source, display its legend, and state its update date. A third-party copy may omit layers or use older source data, so its presence alone does not make it an official source.
The map’s address search depends on the quality of the source address database. A full address that includes the street number, street name, and municipality will usually produce fewer mismatches than a street name alone. If several points share a name, compare the point position, parcel outline, and address fields before accepting the result.
Reading the Map Interface
A typical GIS map viewer has a map canvas, a layer panel, a legend, a search box, and tools for measuring, identifying, printing, or sharing. Some controls appear only when the map is wide enough to display them. On a smaller screen, the same functions may sit inside a menu.
Map Canvas
The map canvas is the central area where features appear. Colored polygons, lines, points, and text represent different types of records. Street names and other labels can change with zoom level because the viewer keeps the display readable by showing only selected labels.
Tool Panels
Tool panels contain controls for layers, identification, measurement, coordinates, and sharing. A magnifying-glass icon often identifies a feature, while a stack of squares can represent layer visibility. Icons vary among viewers, so the panel labels and tooltips provide the safer way to identify a control.
Status and Scale Area
The status area may show cursor coordinates, map scale, selected-layer details, or a source date. Map scale changes with zoom and affects how much detail can be seen. A feature that appears accurate at a wide scale may show a simplified boundary or no boundary at all.
Map Legend and Symbology
The map legend translates colors, line patterns, and point symbols into mapped meaning. For example, one fill color can represent one zoning class, while a dashed line can separate another jurisdiction. Clicking a legend item can control visibility on many viewers, but that action should be confirmed in the current interface.
Color should not be the only clue. Check the legend text and identify the feature directly, especially for flood zones, zoning, utilities, or emergency facilities. Symbols can look similar at a small size, and overlapping features can hide parts of the map.
Live Data and Refresh Status
Real-time tracking applies only to a layer connected to a live sensor, transit feed, vehicle position, or another source that sends frequent changes. Parcel, zoning, and many other administrative layers change through scheduled updates rather than continuous tracking. A live display should include a source and timestamp; without those details, a moving symbol or recent-looking map does not prove that conditions are current.
GIS Map Layers
The current layer list in the official viewer is the proper source for what can be displayed. The categories below reflect the mapped subject groups associated with Erie County and explain what each one can represent by consulting official property owner for additional background verification and notes. A layer name can change, and some layers may be restricted or temporarily unavailable.
Layer Groups and Their Roles
Turn on one layer at a time when possible. That makes the legend easier to read and reduces the chance of mistaking a line or color from another layer for the feature being reviewed.
| Map layer or data group | What it can represent | Point to confirm before use |
|---|---|---|
| Parcel boundaries | Tax-map parcel shapes and parcel identifiers | A parcel map does not by itself prove ownership, deed terms, or the latest assessment record |
| Roads and transportation | Road centerlines, street names, bridges, trails, and transport facilities | Whether the line marks a centerline, pavement edge, or route segment |
| Aerial imagery | Photographic ground conditions at the time of capture | Capture date, season, resolution, and whether the image is orthorectified |
| Zoning | Mapped zoning districts assigned to parcels | The effective date and connection to the adopted zoning ordinance |
| Land use | Existing or planned use categories | Whether a category records current use, a plan, or a proposed action |
| Flood zone | Mapped flood-hazard areas and related features | The effective map date, source program, and any newer federal or state mapping |
| Administrative boundaries | County, municipal, ward, district, or other jurisdictional lines | The legal authority and effective date for each boundary |
| Public facilities | Schools, offices, public works sites, parks, and service locations | Operator, service area, hours, and whether the point is approximate |
| Environmental features | Streams, wetlands, shorelines, protected areas, or monitoring locations | Survey method, field date, and any seasonal or regulatory context |
Reading Layer Metadata
Metadata records what a layer represents, where its data came from, when it was last updated, and any known gaps. Use the layer date to judge whether the map fits the question. A current map can still contain older source records, so the date for each layer matters more than the date displayed for the viewer itself.
The identify tool can reveal attributes for a clicked feature. Results vary by layer and may include a parcel number, zoning code, road name, owner name, acreage, or source reference. An empty result can mean that the selected point falls between mapped features, not that the place has no official record.
GIS Map Features and Controls
Map controls support common tasks such as changing view extent, selecting layers, identifying a feature, and finding an address. The control names and icons can vary among GIS mapping software. Test one control at a time and watch the map status area for a changed scale, selected layer, or coordinate readout.
Basic Map Controls
These controls cover the main actions used during a county map review. Some viewers place several functions in one expandable panel.
| Control | Practical action | Result to check |
|---|---|---|
| Zoom | Use the scroll control, zoom buttons, or a pinch gesture | Parcel and street labels become readable at a suitable scale |
| Pan | Drag the map with a pointer or use the arrow controls | The cursor remains over the intended location |
| Full extent | Return to the entire county or dataset coverage | The map extent matches the service area |
| Identify feature | Select a point, line, or polygon | The result names the topmost visible layer and shows its attributes |
| Layer visibility | Turn named layers on or off | The legend matches the visible map |
| Base map selection | Change the background reference | The basemap does not obscure thematic layers |
| Legend control | Expand or reduce the symbol key | Each visible symbol has a readable description |
| Address or place search | Enter a complete address or place name | The result matches the intended street, municipality, or landmark |
| Coordinate readout | Move the cursor or select a point | The coordinate system and unit are shown |
A Practical Control Sequence
Begin with the address search, then set the zoom level needed for the task. Turn off unrelated layers so the selected feature remains visible. Use identify before drawing a conclusion from color, then check the legend, scale, and layer date. A full-extent reset is useful after a location error because it restores the official coverage and can expose whether the problem came from a misplaced local search.
Erie County NY Geographic Features
The GIS map represents geography through points, lines, and polygons. A point can mark a facility or address, a line can trace a road or stream, and a polygon can show a parcel, zoning district, flood area, or municipal boundary along with official property search when reviewing public filings and document entries. The shape shows location, while attached attributes explain what the feature represents.
County and Municipal Boundaries
County and municipal boundaries support questions about jurisdiction, services, taxes, and representation. Map lines are cartographic representations and can be simplified for display. A legal boundary is described through statutes, deeds, court records, or official survey documents, so a pixel on the screen should not replace those records.
Roads and Streets
The transportation layer can show street names, address ranges, route numbers, bridges, and trails. A road centerline and the edge of a paved road are different geometries. Transportation models and closure notices can also change faster than a printed or downloaded map, making the source date important for route planning.
Water and Environmental Features
Water mapping may use polygons for large water bodies, centerlines for streams, and points for gauges or sample stations. The symbol does not establish navigability, flood risk, water quality, or legal access to the shoreline. Those points require current records from the agency with responsibility for the feature.
Public Facilities and Landmarks
Public facilities can include county offices, parks, schools, fire or rescue stations, and public works sites. A mapped point may represent an entrance, parcel centroid, or address rather than the full footprint. Geographic landmarks can help orient a reader, though a missing label often reflects map scale or label priority rather than the absence of the place.
Planning and Environmental Uses
Urban planning reviews can compare parcel geometry, zoning, roads, and proposed projects. Environmental monitoring can place stream samples, wetlands, flood areas, and monitoring wells beside one another for visual review. These comparisons support analysis, but they do not replace permits, engineering studies, environmental reviews, or field verification.
GIS Mapping, Measurement, and Coordinate Tools
Measurement tools estimate distance, area, coordinates, and locations from the displayed map. These tools are useful for early planning, yet their output depends on the map projection, calculation method, scale, and feature geometry. Treat a measurement as a map-based estimate rather than a survey result.
Measurement Tools
Use the tool named for the unit or result needed. A distance tool may return straight-line distance, a route distance, or a length along a selected line. An area tool may follow visible parcel edges or calculate from a stored geometry.
| Tool | Typical result | Accuracy check |
|---|---|---|
| Distance | Length in feet, meters, miles, or another displayed unit | Check whether the result follows a line or measures directly between endpoints |
| Area | Square feet, acres, hectares, or another unit | Confirm the calculation method, selected feature, and map projection |
| Coordinates | Latitude and longitude, state plane coordinates, or UTM values | Record the coordinate reference system, axis order, and units |
| Location identification | Address, parcel identifier, coordinates, or selected feature | Compare the point with streets, parcel lines, and the result panel |
| Spatial measurement | Distance to a feature, intersection result, or buffer width | Use the same layer and coordinate system for both compared features |
Projection Types and Display
Web map viewers often use Web Mercator for display because it supports worldwide browser-based mapping. Source layers can use another coordinate reference system, such as a state plane system or Universal Transverse Mercator. The viewer reprojects the data for display, which can create curvature or scale differences. Web Mercator can distort area and distance, so a parcel-area measurement should not be treated as a deed calculation.
Coordinate System Checks
Coordinate conversion requires the source coordinate reference system, datum, axis order, and unit. New York records may use NAD83, NAD27, or another defined system. A latitude and longitude pair should not be treated as state plane feet, and the X and Y values should not be swapped without checking the viewer’s documentation. An EPSG code in the layer metadata can prevent that error.
Measurement Accuracy
Zooming closer can expose sharper source geometry, yet a more detailed display cannot repair inaccurate source data. Curved features, thin lines, and overlapping polygons can produce different results depending on where a user clicks. Compare a measurement with a known parcel dimension or source record when possible, and note any difference before using the value for a formal decision.
Geographic Information System (GIS) Mapping Data
GIS data combines location with descriptive attributes. Each dataset needs a responsible source, a defined spatial reference, an update date, and enough metadata for a reader to interpret it. The map viewer presents a working subset of county data, while downloads may expose source files with fewer display features.
GIS Data Sources
A county GIS can combine records from several offices, local governments, state agencies, federal programs, field surveys, and aerial imaging. Tax mapping, planning, public works, emergency management, and environmental offices may each supply a portion of the data. Shared layers can contain disagreements if offices use different names, dates, or boundary rules. The source listed in the metadata must travel with the data.
Geographic Attributes
Attribute fields answer questions that position alone cannot. A parcel may include an identifier, address, owner record, assessed value, zoning code, acreage, and revision date. A road segment may include a route number, street class, surface, ownership, and maintenance responsibility. Stable identifiers are more dependable than visual labels because street names and district names can change.
Attribute querying filters these fields, such as selecting all parcels with one zoning code or all roads with one maintenance class. Results depend on coded values and current records. A blank field can mean “not recorded,” “not applicable,” or “not yet loaded,” so it should not be converted into a positive value.
GIS Data Formats
File format affects which desktop or online GIS software can open a download. The current county download page and its metadata should control the choice of format.
| Format | Data type | Practical detail |
|---|---|---|
| Shapefile | Vector | Uses several related files with the same base name; all needed sidecar files must stay together |
| GeoJSON | Vector | Stores features and attributes in a web-friendly text-based structure |
| GeoPackage | Vector and raster | Places layers, attributes, indexes, and spatial reference details in one file |
| GeoTIFF | Raster | Stores georeferenced image cells and can carry a coordinate reference system |
| File-based geodatabase | Multiple vector and raster datasets | Supports larger GIS projects and related tables within a folder |
GIS Map Data Download and Editing
When a download is offered, read the file description before opening it. Confirm the coordinate reference system, layer date, field definitions, file size, and usage terms. A downloaded copy can become stale after the county publishes a newer version, so the download date belongs with the file.
Shapefile editing requires care because geometry, attribute table, index, and projection files form one dataset. GIS mapping software can edit parcel lines, zoning codes, or other attributes, yet an edited copy is no longer the county’s official layer. Keep source data unchanged, create a separate working file, and record each edit with the date and reason.
Temporal Analysis
Temporal analysis compares features across dated snapshots. A two-year change map can show parcel subdivisions, updated road alignments, or shifted flood mappings, but the dates and rules must align. Different source dates can make a line look changed when only its rendering or classification changed. Time-enabled services can support event queries when the current dataset includes valid timestamps.
GIS Map Analysis Techniques
GIS map analysis techniques turn visible layers into questions about location, relationship, and change. These techniques depend on clean source data, a defined coordinate system, and a clear question. Results from an exploratory map should be checked against source records before being used for a formal application, budget, inspection, or legal action.
Spatial and Attribute Queries
A spatial query asks how geometry relates to another feature. Examples include finding parcels that intersect a proposed corridor or points located within a chosen distance of a stream. An attribute query filters records by stored fields. Combining both approaches can produce parcels that meet a land-use class and fall within a defined area.
Query buffers and radii depend on the projected unit. A distance expressed in degrees cannot be treated as feet. Small changes near a polygon edge can affect whether an intersection test passes, so the selected source layer and tolerance should be documented.
Raster-to-Vector Conversion
Raster-to-vector conversion turns image cells into polygons, lines, or points. This can make an aerial or scanned map searchable, yet traced boundaries inherit the image’s resolution and positional errors. The converted result belongs in a new working dataset unless the county has published and approved that conversion.
Heatmap Generation and 3D Visualization
Heatmap generation groups weighted points into a color surface. The pattern shows concentration, not a confirmed hazard or causal relationship. Filter choices, point weighting, and the neighborhood size can change the shape. A heatmap used for environmental monitoring should retain the original sample points and dates.
3D visualization can extrude building footprints, terrain, or other geometry to show height. Extrusion can exceed the height recorded by a source layer and should be labeled as a visualization choice. It does not create a structural survey or prove compliance with a height limit.
Urban Planning and Environmental Monitoring
Urban planning analysis can compare proposed facilities with parcels, zoning, roads, and mapped constraints. Environmental monitoring can compare sampling points with waterways, flood areas, wetlands, and land-use patterns. A visual overlap identifies areas for closer study. It does not establish ownership, regulatory status, contaminant levels, or the effect of a planned project.
GIS Map API Integration and Custom Map Publishing
GIS map API integration allows a software product or website to request approved map data and display it through its own interface. The county’s current endpoint, supported operations, license terms, key requirements, and update schedule must be confirmed before development begins. A URL seen in browser source code does not by itself grant reuse rights.
GIS Service Types
Several service patterns can support an integrated map, and the correct choice depends on the county’s published resources.
| Service type | Typical function | Item to verify |
|---|---|---|
| REST feature service | Queries features, attributes, and geometry through a web request | Published endpoint, layers, paging limits, fields, and terms |
| Map tile service | Supplies pre-rendered map images by zoom level | Attribution, tile usage limits, caching, and update timing |
| WMS or WFS service | Publishes map images or feature queries through a standard GIS protocol | Version, coordinate reference systems, and permitted request types |
| Geocoding service | Converts an address or place name into map coordinates | Accepted address format, match quality, and returned administrative fields |
| Download service | Supplies source files or a filtered subset of GIS data | License, file format, metadata, update date, and size limits |
Open Source Libraries
Open source libraries such as Leaflet, MapLibre GL JS, and OpenLayers can render maps, controls, and feature layers. They can also support coordinate conversion, spatial indexing, and custom interactions. Library choice depends on the map format, required controls, browser support, and project maintenance needs. The county’s published services remain the data authority even when another library draws the interface.
Custom Styling and Symbology
Custom styling assigns colors, line widths, symbols, and pop-up layouts to each layer. A clear legend should use plain labels and enough contrast to remain readable. Color-blind-safe palettes, varied line patterns, and text labels can prevent confusion. Styling should follow the source meaning rather than assign a new meaning through appearance.
Mobile App and Web Viewer Use
A mobile app can use the same GIS map data as the browser-based viewer, with touch controls and a layout designed for smaller screens. A responsive web map may meet many of the same needs without installation. Before relying on either version, check offline behavior, device support, location permission, and whether mobile users receive the full layer list and metadata.
User Documentation and Map Tutorial
Useful documentation covers the current layer list, update dates, coordinate reference system, search fields, download structure, and known limits. A short GIS map tutorial can walk through opening the viewer, finding an address, turning on a layer, selecting a feature, checking the legend, and recording the source date. The tutorial should use controls visible in the current county interface rather than icons copied from another product.
Erie County NY GIS Map Updates
GIS updates come from many workflows, so a single refresh date does not cover every layer. Parcel changes may follow assessment or recording events, roads may change after construction, and imagery may arrive on a project schedule. The viewer can be current while one source layer remains older.
Layer Refresh Cycles
Check for a layer date, publication date, or “last updated” value in the legend, identify panel, download page, or metadata. If no date appears, treat the layer as undated and confirm it with the publishing office. A cached browser view can also show an older image, so refreshing the page may be needed before judging the source date.
Boundary and Address Changes
Boundary changes may arise from annexation, court action, local ordinance, or another formal action. Address changes can reflect new addressing, renumbering, or a correction to a source database. A map line or point may change before the supporting public notice or record appears. Effective dates help connect the map change to the action that created it.
Checking for Updated Map Layers
Open the layer panel, inspect the visible legend, and compare the selected feature’s date with a downloaded or printed version. If two official products disagree, record the layer name, map scale, date, and source for each. This creates a clear question for the responsible office and avoids relying on an unverified value from a secondary map.
GIS Map Printing and Sharing
Printing, saving, and sharing tools depend on the county viewer. Some viewers create a printer-friendly page, others export an image or PDF, and some only place a location in a shareable URL. The current interface should be checked for the exact output and any attribution required by the source.
Print a Map View or Save the View
Set the scale, layers, legend, and visible labels before printing. A print made at a wider scale may show fewer parcel lines than the screen view because of line simplification. Save or bookmark the view if the viewer preserves its URL state, and record the layer date separately because a bookmark may open a newer data set later.
Export and Share a Map Location
An exported image can be easier to send through email or a document, but it loses interaction and may separate the map from its legend. A shared URL can preserve layers and zoom, but the recipient’s browser may load a newer version. Send the layer names and viewing date with either format when the map supports a planning, inspection, or public discussion.
Sharing Checklist
- Include the map title, Erie County context, visible layer names, viewing date, scale, legend, and source attribution.
- State whether the view is for general reference or a specific analysis, especially when layers were combined by the sender.
- Remove personal markers or location pins that are not needed for the reader’s task.
- Check that an exported file opens correctly and that its labels remain readable at the intended size.
- Open a shared URL in a separate browser window to confirm the recipient sees the expected extent and layers.
- Follow any usage terms shown with an export, download, or public map service.
GIS Map Accuracy and Limitations
Map accuracy has several parts. Positional accuracy concerns where a feature sits, attribute accuracy concerns its recorded values, logical accuracy concerns whether features relate correctly, and temporal accuracy concerns whether the record reflects the intended date. A map can perform well in one part and poorly in another.
GIS Data Accuracy Assessment
Begin with the source and date listed in the metadata. Compare the map with a control point, parcel dimension, street centerline, or official boundary record. Review the stated positional tolerance, survey method, imagery resolution, and transformation used for the display. Browser pixels are not survey measurements, and a map-scale estimate cannot reveal a small boundary error.
Attribute accuracy needs a source check too. A parcel identifier copied from another record, a default zoning code, or an incomplete address can be stored in the map and still be wrong. Compare selected attributes with the department that produced the record. The GIS map often shows a value faster than it verifies the value.
Map Display and Boundary Limitations
Display simplification shortens parcel lines, rounds corners, and removes small features to keep the map readable. Labels can overlap or disappear at certain zoom levels. Dense urban areas can place several polygons under one pixel, making an identify result depend on feature order. Small features can disappear at broad scales even though they remain present in the source data.
Boundary representation also depends on purpose. A parcel tax line, public right-of-way, municipal line, and survey line may occupy slightly different places. A visible polygon reflects the stored geometry and tolerance used by its publisher. It does not settle a legal dispute over a boundary.
Data Update Delays
Update delays can occur between a field change, the office’s record, the database update, the map service refresh, and a user’s browser. One stage may move faster than another. A visible timestamp records the state of the published layer, not the exact moment a real-world change occurred.
Reading the GIS Map Disclaimer
The disclaimer shown by the viewer or download controls the limits placed on that product. Read it before reusing a map or data file. For property boundaries, permits, flood decisions, emergency conditions, or legal jurisdiction, the current record issued by the responsible agency should control. A map can support a question without answering it with binding authority.
GIS Map Problems
Most viewer issues fall into loading, search, layer, feature, date, or measurement categories. Check one stage at a time because a failed layer can resemble a failed viewer, and an address mismatch can resemble an inaccurate map. Record the browser, page address, layer name, action attempted, and exact message before seeking help.
Problems and Checks
GIS maps may sometimes display errors due to outdated data, browser issues, or incorrect settings. The table below highlights common problems, checks to perform, and possible causes to help identify the issue.
| Problem | Checks | Possible Cause |
|---|---|---|
| Map Not Loading | Refresh the page, try another browser, and check portal status. | Network restrictions, browser cache, service outage, or blocked scripts. |
| Location Not Found | Enter the full address, remove punctuation, or try a nearby street. | Missing address point, outdated data, or incorrect search format. |
| Layer Not Displaying | Check layer visibility, zoom level, map extent, and legend. | Layer turned off, unavailable, outside the current view, or hidden. |
| Incorrect Map Feature | Check the selected feature, data source, and publication date. | Outdated information, boundary differences, or data-entry errors. |
| Outdated GIS Layer | Review the layer date and compare it with the latest published data. | Scheduled update delays or cached map information. |
| Measurement Problem | Verify units, coordinate system, selected area, and calculation method. | Incorrect units, unsuitable projection, or inaccurate map selection. |
Preparing a Support Request
A useful support request includes the official page used, the address or coordinates involved, the layer name, the map scale, the layer date, and a screenshot showing the issue. Remove private data that is not needed to diagnose the problem. Clear details help staff reproduce the map condition and compare it with the source record.

Frequently Asked Questions
Find quick answers about using the Erie County Gis Map, its layers, data download options, and support resources.
How do I search the Erie County Gis Map?
Open the county’s online GIS portal and enter an address, parcel number, or keyword in the search box. The map will center on the location and highlight the matching feature. Click the highlighted item to view its attributes, such as owner name or land use. Results update as underlying layers refresh, so the displayed date may differ from the official record. For detailed queries, use the filter icons to narrow results by layer type or date range.
What layers are available on the interactive GIS map?
The interactive GIS map includes parcels, zoning, flood zones, street networks, and utility corridors. Additional layers show schools, parks, and voting districts. Each layer can be turned on or off using the layer control panel on the right side of the screen. When a layer is active, its symbols follow the map legend, making it easy to distinguish feature types. Users can combine layers to compare information, such as overlaying flood zones with property boundaries.
Can I download GIS map data for my project?
Yes, the portal offers data download links for most layers. After selecting a layer, click the download icon to choose a format such as Shapefile, GeoJSON, or CSV. Downloads include the current version of the layer and a metadata file that lists the source, date, and projection. Large datasets may require a brief wait while the server prepares the file. If you need historical versions, contact the county GIS office during regular hours.
How to convert coordinates using the GIS map tool?
The map includes a coordinate conversion widget in the toolbar. Select the tool, then click a point on the map or type the coordinate values. Choose the source and target projection from the dropdown menus, such as NAD83 to WGS84. The widget instantly displays the converted coordinates in latitude‑longitude or UTM format. You can copy the results to the clipboard for use in other applications. This feature works for both single points and batches entered via a text file.
Where can I get help with GIS map tutorials?
The county website hosts a GIS tutorial section with step‑by‑step videos and written guides. Topics cover basic navigation, layer management, and exporting data. For personalized assistance, call the information line at (716) 858‑6000 during office hours. Staff can walk you through specific tasks or direct you to additional resources such as the GIS user documentation PDF. Community workshops are announced on the portal’s news feed.
