100’s of Features

Fast and Powerful Mapping Engine 

We designed GeoData Explorer after using countless other mobile apps and being frustrated with their limited Geospatial Data format support, no attribute table viewing and lack of easy use and sometimes vendor lock-in.  So we set out to engineer this product to meet our specifications and realized the benefit it would have to other users.

Map Viewing

Configure different basemaps from our basemap picker or add a new one URL. Display Coordinates (GPS Lat Long, UTM, MGRS, USNG, Maidenhead) and Graticule Lines Our mapping engine is one of the fastest rendering of data you’ll find.

Offline/Disconnected Data

The app supports many formats of offline files and database. (Mbtiles, GeoPackage, Shapefiles, GeoJSON, KML)

Spot Elevation

Display Spot Elevation Values for anywhere with and without internet (when offline data is loaded)

We support MapZen Terrarium PNG Tiles Format from tile server and inside MBTILES. Display Terrain Profile view Graph (see the slope/steepness)


Draw features and assign attributes

Drop a point, Ciricle, Line, Polygon feature on the map and assign unlimited keys and values (attributes) to that location and save as GeoJSON (coming soon save as GPKG).  Also, attach media to the location. Full styling control for symbology representation.

Your Position on Map

Show your position on the map via Geolocation Geolocation feature works with GNSS Receivers (GPS) or WiFi via IP Address. Display routes on the map as well.  Display North Compass Arrow Display Coordinates in multiple formats

Spatial Bookmarks

Save map extent/location so you can easily come back to an area. Create unlimited spatial bookmarks

BaseMap Picker

Select Multiple Basemaps from open source and commercial providers. Google, Bing, ESRI, Stamen, Thunderforest, Open Street Map, HERE, CartoDB, NASA and others.


Use Annotation Tools like crayon and marker and hatch patterns with color picker

View Attribute Table

View attribute table and sort and filter

GeoPackage Support

We full support OGC GPKG – GeoPackage SQLite format for offline vector features and raster tiles and elevation tiles

Geospatial Analysis

Perform analysis and geoprocessing operations like Buffer, voronoi, center, envelop, convex, bounding box and other operations all offline with no server-side processing and include previous operations for chaining commands together


Show weather overlays like precipitation, clouds, snow, heat index and many other overlays

Display Grids

display reference graticule and gridlines and numbers Including  Metric, Imperial,UTM and MGRS


Catalog/Project Files

JSON Catalog Files and Catalog Editor

Vector Tiles

If you load a GeoJSON file the app will automatically split the file (up to 200mb) into tiles 256×256 pixels and different zoom levels for rapid display and rendering. We also support MapBox Vector Tiles (gzipped PBF) inside MBTiles or via an online XYZ Tile Server.  We also support Open Street Map Vector Tiles with different stylesheets

Google Services Integration

Swipe to compare maps

Use the Layer Swipe tool to easily compare datasets or basemaps


Label vector features & drawing layers

Also include mouseover  instead of permanent label

Support for high precision external Bluetooth GPS / GNSS Receivers

Take your survey and mapping and GIS data visualization and data capture to the next level with submeter sub-foot and centimeter (RTK) positions via external Bluetooth, Serial, USB GNSS Receivers (GPS Global Positioning Systems).  You can even work with Real-Time Networks (RTN) Continous Operating Reference Receivers and other services for position corrections.
