A full-stack geospatial database, API server, and rendering engine — embedded directly inside ATAK on your Android device.
At the core of the plugin is DuckDB with its spatial extension — an embedded, columnar analytical database purpose-built for fast aggregations and complex spatial queries. Run SQL against millions of features with sub-second performance, entirely offline.
A local OGC API Features endpoint runs directly on-device, enabling standards-compliant access to your spatial data. Custom endpoints also provide KML and Shapefile output alongside standard GeoJSON.
| API Endpoint | Format | Filtering | Offline |
|---|---|---|---|
| OGC API Features | GeoJSON | CQL2 | ✓ |
| OGC API Tiles | MVT | BBox | ✓ |
| Custom KML Export | KML/KMZ | Attribute | ✓ |
| Custom Shapefile | SHP/DBF/SHX | Attribute | ✓ |
Full NGA GeoPackage library integration for reading/writing vector features and serving dynamic raster tiles, including support for 3395 World Mercator map tiles. PMTiles bring cloud-optimized, single-file vector and raster tile archives.
Pre-load GeoPackage files containing terrain, infrastructure, and threat data. During operations, query features using DuckDB Spatial to find all bridges within 5km of a route, all buildings over 3 stories, or all water sources within line-of-sight — all without network connectivity.
MapLibre GL Native serves as the vector tile rendering engine, transforming vector tiles into raster tiles on-the-fly for seamless display inside ATAK's map view. Custom tile.xml configurations support multiple tile sources simultaneously.
Search and discover geospatial data from dozens of pre-configured catalog services with a unified fused search interface:
| Catalog Protocol | Data Types | Example Sources |
|---|---|---|
| OGC API Records | Vector, Raster, Services | USGS, NOAA, OpenTopography, EuroGEOSS |
| CSW 2.0.2 | ISO 19115 Metadata | ScienceBase, NGDC, EPA, NASA GCMD |
| STAC | SpatioTemporal Assets | Microsoft Planetary Computer, Element 84 |
| CKAN | Open Government Data | data.gov, European Data Portal, HDX |
| Socrata | Civic/Open Data | City & County portals, State agencies |
| OpenDataSoft | Enterprise Open Data | Corporate portals, Regional data hubs |
| THREDDS | Weather, Climate, Ocean | NOAA, NCAR, University servers |
| USGS EarthExplorer | Satellite Imagery, Elevation | Landsat, Sentinel, NAIP, SRTM |
| NOAA Data Access | Weather, Marine, Climate | NWS, NCEI, CO-OPS, NESDIS |
Query multiple data catalogs simultaneously to discover all available imagery, elevation data, and vector features for an area of interest. Search USGS EarthExplorer for Landsat, NOAA for weather data, and CKAN portals for infrastructure datasets — then download directly to GeoPackage for offline use.
Connect to THREDDS (Thematic Real-time Environmental Data Distribution Service) catalogs for weather, climate, and oceanographic data. Browse datasets, query metadata, and download NetCDF subsets for on-device analysis.
