Data Sources

Loads GeoJSON, zipped Shapefile, KML/KMZ, GeoParquet and other vector formats as layers.

Adds GeoTIFF/COG rasters via URL or file with per-layer band, ramp and stretch controls; multiband COGs support bounded clicked-pixel spectral profiles with PNG/CSV export, while WASM COG layers auto-zoom to their bounds and preserve 128-bin histogram, ramp, and palette previews across style changes.

Imports delimited text from URL or file with configurable delimiter and CRS; without coordinates it is added as a table.

Imports DXF/DWG files with detected layers and typed or preset CRS, loading supported geometries only.

Reads .gdb folders with detected layers and CRS for direct map use. Desktop application and installed processing service only.

Imports geolocated photos with thumbnails; GPS-less photos are rejected or placed manually.

Loads GPX tracks, waypoints, track points, routes and route points from URL or file; at least one type must be selected.

Opens .mbtiles files showing tile type/format and, for vector tiles, their source layers. Desktop application only.

Imports OpenStreetMap data from .osm.pbf files into editable layers. Disabled while another PBF import is running.

Adds tiled XYZ imagery such as orthophotos or thematic basemaps by setting a URL template, tile size and short URL.

Overlays WMS imagery by configuring URL, layers, styles, format, size, version and transparency.

Downloads WFS features with geometry and attributes as a queryable vector layer.

Add WMTS services via GetCapabilities with layer, tile-matrix-set, style and format selection.

Queries an OGC API - Features collection by bbox and date and adds the results as selectable vector data.

Renders vector tiles from an OGC API - Vector Tiles service for large coverages at scalable detail.

Adds features, vector tiles, or rendered raster imagery from an ArcGIS service or portal item; MapServer sublayers and ImageServer raster functions can be browsed; optional token for secured services.

Converts a GeoRSS feed of news, alerts or observations into a feature layer that maps each event's location.

Opens a concrete STAC catalog or asset URL and adds the selected COG asset as a layer for date/area analysis. To browse providers, use Plugins → STAC Catalogs or Vantor Open Data.

Projects a video onto terrain using the lon/lat of its four corners to relate it to its location. MP4 must be served over HTTPS.

Adds scatter, heat, hexbin, 3D grid, contour, trip, icon and glTF model layers powered by deck.gl.

Reads columnar geometries and attributes from a GeoParquet file, selects its primary geometry and declared CRS from file metadata (or native logical metadata), reprojects before rendering, and can synthesize WGS84 points from conventional longitude/latitude or x/y columns.

Loads indexed FlatGeobuf features by URL or file and displays them as a queryable vector layer.

Reads a PMTiles archive, detects whether it holds imagery or features, and adds its layers. Local files depend on the environment.

Visualizes a multidimensional Zarr variable as a raster selectable by dimension, with color bounds, ramp and opacity controls.

Opens local NetCDF/HDF files or direct range-readable .nc, .nc4, .h5, .hdf5 or .cdf URLs, selects dimensions and single-band or RGB rendering, and identifies pixels for sampled spectral profiles. Hyperspectral and 3D inspection is bounded to 192 × 192 cells, 64 bands and 12 MiB decoded per inspection; larger inputs use the 2D raster path. Kerchunk manifests remain supported for cloud-optimized inputs.

Loads LAS, LAZ or COPC point clouds to examine terrain, vegetation or structures in 3D. The resource must be readable.

Places a Gaussian splatting scene in 3D with position, rotation and scale; requires a compatible splat resource.

Loads a 3D Tiles dataset of hierarchical buildings, meshes or territorial models; child resources must be accessible.

Places a glTF model on the map at a defined location and orientation for advanced visualization. Requires a model URL.

Queries tabular or spatial data with SQL and converts the results into a new analysis layer, editable when convertible.

Connects PostGIS tables as tiles or editable layers and syncs changes back. Desktop only; requires local service and credentials.

Adds a credential-free Apache Iceberg table from metadata or a REST catalog, lets you choose a GEOMETRY column, and materializes a bounded GeoJSON snapshot in the browser. Credential-bearing locations and signed URLs are rejected. Loads cap at 100,000 rows and 64 MiB of decoded GeoJSON; direct HTTP metadata with Content-Length above 100 MiB is rejected when reported, but that HEAD check cannot preflight aggregate manifest/data fan-out. Refresh is manual.

Browse saved services, recent projects, database connections, and pinned file folders in one searchable tree with favorites.

Save configured service forms under named categories and move the whole library between machines as a JSON file.

Turn an address column into mapped points during CSV import, with explicit consent, capped requests, and a match summary.

Render KML/KMZ ground overlays aligned on the map, stream region-tiled super-overlays, and animate time-stamped overlay groups.

Place COLLADA models from KMZ archives or URLs on the globe as textured 3D objects, converted automatically to glTF.

Add vector and raster layers by dropping files straight onto the map, with warnings for very large datasets.

Serve PostGIS tables as read-only vector tiles through a bundled Martin server managed inside the app. Desktop only.

Open large local vectors, shapefiles, and MBTiles through native readers beyond browser memory limits. Desktop only.
