Supported Layers

Server Layer	Layer Description
ArcGIS FeatureServer Layer	A dynamic layer sourced from an ArcGIS FeatureServer, allowing interactive querying, editing, and visualization of vector features such as points, lines, and polygons.
ArcGIS MapServer Layer	A layer sourced from an ArcGIS MapServer, supporting both vector and raster data, often used for complex map compositions and symbology.
Dataverse Layer	A custom layer that visualizes data from Microsoft Dataverse entities, such as accounts or work orders, enabling integration of business data with geographic context.
MapLibre Style Layer	An overlay or operational layer rendered using MapLibre GL styles, supporting advanced vector data visualization and interactivity.
Slippy Image Layer	A raster image overlay using the Slippy Map tiling scheme, suitable for displaying custom imagery or thematic overlays above the basemap.
WMS Layer	Displays map images generated on-the-fly from geospatial data hosted on a remote server using the OGC WMS standard. Ideal for viewing dynamic maps from external sources.
WMTS Layer	Serves pre-rendered map tiles for fast and efficient map display using the OGC WMTS standard. Commonly used for basemaps and high-performance mapping.
WFS Layer	Provides access to vector features (points, lines, polygons) as raw data using the OGC WFS standard. Suitable for querying, downloading, and editing geospatial features.

3D/Elevation Layers

3D Layer Type	Layer Description
Terrain-RGB Layer	Raster tiles with elevation data encoded in RGB channels, supporting Digital Elevation Models (DEM) and 3D terrain visualization.
Terrain Vector Layer	Vector tiles containing contour features with elevation properties, ideal for contour line visualization and elevation queries.
3D Terrain WMS Layer	WMS service providing elevation/terrain data for 3D visualization and analysis applications.
3D Terrain WMTS Layer	Pre-rendered terrain tiles optimized for fast 3D terrain display and elevation analysis.

Layer must have the following:

Extent
- Should contain finite coordinate values
- Should contain spatialReference object containing the wkid
Query capability
- All available fields must be queryable
- If any fields are hidden, they must also be hidden from being queryable
- where=(1=1) query should be enabled and should return data
- Query must allow features/geometry to be returned
- Query should allow esriGeometryEnvelope geometry as a filter
Drawing Info/Rendering Info of types:
- simple, with the following symbol types:
  - esriSMS
  - esriSLS
  - esriSFS
  - esriPFS
  - esriPMS
  - esriTS
- uniqueValue, with the following symbol types:
  - esriSMS
  - esriSLS
  - esriSFS
  - esriPFS
  - esriPMS
  - esriTS
Geometry type must be:
- Polygon
- Polyline
- Point
If MinScale and MaxScale are defined:
- Must be in the correct order i.e.
  - if both are provided, MaxScale should be less than MinScale
  - if MinScale is 0, this means the layer will be always visible until it reaches the MaxScale threshold
  - if MaxScale is 0, this means the layer will always be visible after it exceeds the MinScale threshold
  - if both values are 0, this means the layer will always render

Example Postman Collection

Use the following Postman collection to test if your layer is likely to function as expected. This will help you test the endpoints mentioned above, as well as allow you to compare the resulting JSON against the requirements.

ArcGIS FeatureServer Collection

ArcGIS MapServer Layer

Required Endpoints

Must have MapServer in the URL. This is not case-sensitive.

Can provide URL with or without a trailing /.

Ending the URL with MapServer or MapServer/ will load available layers within the map service for selection.

Providing a layer specific index at the end of the URL (example: MapServer/1 or MapServer/1/) is NOT SUPPORTED

Required Response

Layer must have the following:

Extent
- Should contain finite coordinate values
- Should contain spatialReference object containing the wkid
Query capability
- All available fields must be queryable
- If any fields are hidden, they must also be hidden from being queryable
- where=(1=1) query should be enabled and should return data
- Query must allow features/geometry to be returned
- Query should allow esriGeometryEnvelope geometry as a filter
Drawing Info/Rendering Info of types:
- simple, with the following symbol types:
  - esriSMS
  - esriSLS
  - esriSFS
  - esriPFS
  - esriPMS
  - esriTS
- uniqueValue, with the following symbol types:
  - esriSMS
  - esriSLS
  - esriSFS
  - esriPFS
  - esriPMS
  - esriTS
Geometry type must be:
- Polygon
- Polyline
- Point
If MinScale and MaxScale are defined:
- Must be in the correct order i.e.
  - if both are provided, MaxScale should be less than MinScale
  - if MinScale is 0, this means the layer will be always visible until it reaches the MaxScale threshold
  - if MaxScale is 0, this means the layer will always be visible after it exceeds the MinScale threshold
  - if both values are 0, this means the layer will always render
Export of PNG32 image tiles should be enabled and available

Dataverse Layers

To utilise dataverse as layers please ensure:

Dataverse record is configured correctly.
At least some records have valid locations.

This is a BETA feature. More documentation is coming soon.

MapLibre Style Layers

A MapLibre style layer depends on a Style JSON and vector tile sources.

Required Endpoints

Type	Example
Main URL	`https://example.com/styles/your-style/style.json`
Style JSON	`https://example.com/data/v3/tiles.json`
Tile Endpoint	`https://example.com/data/v3/{z}/{x}/{y}.pbf`

This JSON references:

Tile sources (vector, raster, GeoJSON)
Layer definitions (rendering rules)
Sprites and fonts (optional)

Slippy Image Layer

Required Endpoints

Slippy maps use a URL template to retrieve tiles based on the zoom level and x/y tile coordinates:

Type	Example
URL	`/tiles/{z}/{x}/{y}`

Where:

{z} = zoom level

{x} = tile column

{y} = tile row

WMS (Web Map Service) Layer

Layer Description

A WMS layer displays map images generated on-the-fly from geospatial data hosted on a remote server. WMS is an OGC standard, ideal for viewing dynamic maps from external sources.

Required Endpoints

Must have service=WMS in the URL. This is not case-sensitive.

You typically provide a base URL, and the application will handle the required parameters (e.g., LAYERS, STYLES, FORMAT, BBOX, etc.).

Example:
https://example.com/geoserver/ows?service=WMS&version=1.3.0&request=GetMap

Required Response

The server should return a map image (PNG, JPEG, etc.) in response to a GetMap request. The response is not JSON, but an image file.

WMTS (Web Map Tile Service) Layer

Layer Description

A WMTS layer serves pre-rendered map tiles (small images) for fast and efficient map display. WMTS is an OGC standard, ideal for basemaps and high-performance mapping.

Required Endpoints

Must have service=WMTS in the URL or follow a tile URL template.

Example:
https://example.com/geoserver/gwc/service/wmts?service=WMTS&request=GetTile&layer=layername&tilematrixset=EPSG:3857&TileMatrix=10&TileRow=512&TileCol=1024&format=image/png

Or a template:
https://example.com/tiles/{z}/{x}/{y}.png

Required Response

The server should return a map tile image (PNG, JPEG, etc.) for the requested tile coordinates.

WFS (Web Feature Service) Layer

Layer Description

A WFS layer provides access to vector features (points, lines, polygons) as raw data, not just images. WFS is an OGC standard, ideal for querying, downloading, and editing geospatial features.

Required Endpoints

Must have service=WFS in the URL. This is not case-sensitive.

Example:
https://example.com/geoserver/ows?service=WFS&version=2.0.0&request=GetFeature&typeName=layername

Required Response

The server should return feature data in GML, GeoJSON, or another supported vector format.

Terrain-RGB Layer

Layer Description

A Terrain-RGB layer provides elevation data encoded in raster tiles using RGB color channels. Each pixel's RGB values represent elevation measurements that can be decoded to create Digital Elevation Models (DEM) for 3D terrain visualization, slope analysis, and elevation queries.

Implementation Method

Configure as a Slippy Image Layer with terrain-RGB tiles.

Required Endpoints

Must serve terrain tiles in PNG format with RGB-encoded elevation data.

Example:
https://api.mapbox.com/v4/mapbox.terrain-rgb/{z}/{x}/{y}.pngraw?access_token=YOUR_ACCESS_TOKEN

Elevation Decoding

Elevation values are decoded from RGB pixels using the formula:

elevation = -10000 + ((R * 256 * 256 + G * 256 + B) * 0.1)

Where R, G, B are the red, green, and blue channel values (0-255), and elevation is returned in meters.

Required Response

The server should return PNG tiles with RGB-encoded elevation data. Each pixel represents an elevation value that can be decoded using the standard Terrain-RGB formula.

Use Cases

Digital Elevation Model (DEM) visualization
3D terrain rendering
Elevation querying at specific coordinates
Slope and watershed analysis
Terrain profiling and cross-sections

Terrain Vector Layer

Layer Description

A Terrain Vector layer provides elevation data as vector features containing contour lines with elevation attributes. This layer type is ideal for displaying contour lines and performing elevation queries at specific points.

Implementation Method

Configure as a MapLibre Style Layer or query via Tilequery API for Mapbox Terrain vector tilesets.

Required Endpoints

Must provide vector tiles with contour features containing elevation properties.

Example:
https://api.mapbox.com/v4/mapbox.mapbox-terrain-v2/tilequery/{lon},{lat}.json?access_token=YOUR_ACCESS_TOKEN

Data Structure

Vector tiles must contain features in a "contour" layer with:

ele property: elevation value in meters
index property: for highlighting index contour lines
Geometry: polygon or line features representing elevation contours

Required Response
