3D Map Explorer turns any Windows workstation into a complete, offline geospatial hub — 3D visualization, real-time collaboration, multi-format data mastery, and now true 3D / Z-enabled editing over GeoPackage. No cloud. No ArcGIS license. No infrastructure.
Valuable geospatial data is trapped on individual workstations. Enterprise GIS servers cost a fortune and take weeks to stand up. Cloud tools raise data-sovereignty concerns. Field teams go dark the moment the network drops.
Enterprise GIS stacks demand dedicated hardware, licenses, and a half-FTE just to keep the lights on.
Cloud sync is a non-starter for classified, regulated, or commercially sensitive geospatial data.
Field, tactical, and remote teams lose every collaborative capability the moment the uplink fails.
A WPF desktop host with an in-process ASP.NET Core server: 30+ formats and six databases go in, open standards come out — OGC, Esri REST, I3S, STAC, vector tiles, streams. Nothing leaves your network.
Full technical architecture with request flows and data pathways in ARCHITECTURE.md
Built on an in-process ASP.NET Core server, the desktop hosts, serves, edits, analyzes, and shares geospatial data — fully offline if required.
True 3D (Z + M) editing over GeoPackage through an ESRI-compatible FeatureServer and the native Editor widget — round-trips elevation exactly.
Deep-dive →One click turns the workstation into a LAN-wide OGC / ESRI / 3D-Tiles endpoint. Zero config, zero infrastructure.
How it works →I3S SceneLayers from .slpk, Gaussian splats, OGC 3D Tiles, LiDAR point clouds, and streaming Cloud-Optimized GeoTIFF.
See the stack →Shadow & solar potential, viewshed, slope/aspect, routing, spatial statistics — with live 3D visualization.
Explore tools →USGS quakes, NOAA weather, AIS vessels, FAA aircraft, Meshtastic mesh, TAK/CoT, APRS, and IoT sensors.
Live data →GeoPackage, GeoJSON, ESRI Geodatabase, Shapefile, KML, PMTiles, FlatGeobuf, COG — read, convert, serve.
Full format list →Beyond the six pillars, these features have landed in the latest releases — search public imagery catalogs, map your existing databases, fly drone video geo-locked to the terrain, import CAD, stream live feeds straight into ArcGIS, and serve terrain & imagery to Cesium, Unreal, Unity, and Godot with no Cesium ion or ArcGIS Online dependency.
Search Element 84 & Planetary Computer from one box, and publish your own rasters and point clouds as a spec-conformant STAC API 1.0.0.
Search & publish →Postgres, MySQL, SQLite, SQL Server, BigQuery, Google Sheets — spatial tables auto-discovered and served as MVT, OGC Features, and FeatureServer.
Map your data →STANAG/MISB KLV playback with a live sensor footprint, DJI→STANAG conversion, and optional YOLO-E detection — RTSP/UDP/SRT supported.
Geo-locked video →DWG / DXF / DGN onto the map via control-point or source-EPSG georeferencing, served as GeoJSON, MBTiles-vector, or GeoPackage.
Import drawings →Subscribe to SensorThings, SOS, GTFS-rt, and Moving Features into DuckDB — then expose moving data as a native Esri WebSocket StreamLayer.
Live streaming →Air-gapped terrain & imagery for Cesium, ArcGIS Maps SDK for Unreal/Unity, and Godot — quantized-mesh, WMTS, TMS XML, and LERC. For mission-planning & simulation enclaves without Cesium ion or ArcGIS Online.
Engine integrations →The full feature hub — the six pillars plus everything above, with deep-dive pages and the promo deck.
All features →The headline capability of this release: a real, end-to-end 3D (Z + M) editing pipeline over GeoPackage, wired into the running app and the ArcGIS Editor widget.
