Adding data
The Add Data menu is the primary way to import layers into the Map Builder. Sources are organized into Files, Web services, Cloud formats and 3D layers. You can also drag files straight onto the map.
| Source | Notes |
|---|---|
| Vector layer | GeoJSON, GeoParquet, FlatGeobuf, zipped Shapefile, GeoPackage, KML/KMZ, GML and other vector formats, from a file or a URL. |
| Raster layer | GeoTIFF and Cloud-Optimized GeoTIFF (COG), from a file or a URL. |
| Delimited text | CSV/TSV files, using longitude and latitude columns to create point features. |
| GPX | GPX files, split into waypoint, track and route layers. |
Vector files are automatically reprojected to EPSG:4326 on load.
Web services
Section titled “Web services”| Source | Notes |
|---|---|
| XYZ | Raster or vector tile services using {z}/{x}/{y} URL templates. |
| WMS | Web Map Service layers, with click-to-identify where available. |
| WFS | Web Feature Service layers, with optional auto-refresh. |
| WMTS | Web Map Tile Service layers. |
| ArcGIS | ArcGIS FeatureServer or VectorTileServer layers. |
| STAC | Search a STAC catalog and add matching raster items. |
Cloud-native formats
Section titled “Cloud-native formats”| Source | Notes |
|---|---|
| GeoParquet | Columnar vector format supporting HTTP range requests for large remote files. |
| FlatGeobuf | Cloud-optimized vector format with spatial indexing. |
| PMTiles | Single-file vector or raster tile archive. |
| Zarr | Chunked, cloud-native multidimensional arrays. |
3D layers
Section titled “3D layers”| Source | Notes |
|---|---|
| 3D Tiles | OGC 3D Tiles, persisted with your project. |
| LiDAR | Point-cloud visualization rendered with deck.gl. |
| Gaussian splats | Gaussian splat scenes. |
Drag and drop
Section titled “Drag and drop”Drag vector files (GeoJSON, zipped Shapefile, KMZ) or raster files (GeoTIFF/COG) straight onto the map. GPX files are split into named layers automatically.
From your Datastore
Section titled “From your Datastore”Add Data can also pull a layer straight from your Datastore, where your own assets and saved web maps live. Anything you import is stored there too, so it is one click away next time.
Basemaps
Section titled “Basemaps”Basemaps are added from the same Add Data flow. Pick a basemap style, or bring your own provider by adding your account key (for example Mapbox or MapTiler). Your provider keys are stored securely and are never written into the saved map (see Integrations). The active basemap sits at the bottom of the Layers panel, where you can toggle its visibility and opacity.
Trusted open data
Section titled “Trusted open data”Beyond your own sources, the Data Hub lets you browse and import curated open data, including Overture Maps and Sentinel-2 imagery, straight into your Datastore.
