Announcing Release of New Version GEOINT DATA EXPLORER 1.0.0 iOS NGA’s GEOINT App Store

Announcing Release of New Version GEOINT DATA EXPLORER 1.0.0 iOS NGA’s GEOINT App Store

GEOINT DATA EXPLORER – *Version 1.0.0* launched on NGA’s GEOINT APP STORE

GEOINT DATA EXPLORER is a rapid data visualization and discovery mapping app that works equally well offline into disconnected limited availability environments (D-DIL) as well as when partially or fully connecting to online mapping services, tile layers and catalogs. The Map has powerful data management and built-in tools for analysis and display of geospatial data.

GEOINT Data Explorer is meant to be a mobile GEOINT Toolkit that facilitates GIS Data Visualization, Discovery, Mapping,Data Creation and Editing and Analysis App that works 2D and 3D!
Fast performance, easily control the display of your data and mashup local and internet data, perform rapid analysis, data creation, editing, and visualization.

Announcing the Release of Print Map

Announcing the Release of Print Map

Print Map- Version 1.0.0 launched on Google Play Store for Android.

Print Map is used for preparing offline high quality georeferenced PNG maps and PDF from custom vector tile basemaps (OpenMapTiles and MapBox) with custom configurable stylesheets.


Easily Export High Quality Maps from a mobile app
Set initial view by searching or entering Lat Long

Choose Output format (PNG or PDF)

Select a Map Style based on either MapBox or OpenMapTiles Vector Tile Basemaps and Satellite Imagery

Set your page size and DPI

The PNG Images can optionally include PGW -Worldfile and PRJ-Projection sidecar files that are recognizable by all GIS Mapping Software packages and many mobile apps. The PNG images can also be inserted into reports and documents.

Announcing the Release of Tile Server

Announcing the Release of Tile Server

Tile Server – Version 1.0.0 launched on Google Play Store for Android.

Serve Map Tiles (XYZ or WMTS) URL’s to mapping clients/apps/software or to advanced map viewer.
From MBTILES or GPKG (GeoPackage) SQLite Databases/files that contain raster tiles, vector tiles, elevation/terrain tiles, other tile data in the tile_data blob.


Serve Static Geospatial Data (GIS) files like KML/KMZ, GeoJSON, CSV, GPX, CZML, SHP, 3DTiles, 3DModels (gltf/glb) and others. This is basically a file server that any file type including zip file has an endpoint and accessible for streaming or downloading across the network.

Discover-able Endpoints and webpages
WiFi turned on is required to run this app and have it get an IP Address from the network.
This is a local IP Address NOT internet accessible. So only users on your local network can access this data.

ipaddress:8080/discover – web page listing of all the tile layers and static files
ipaddress:8080/services – JSON response and access to tile.json for each layer
ipaddress:8080/map – advanced map viewer with quick access to tile layers and adding local Shapefiles, GPKG, GeoJSON, KML, GPX, CSV
ipaddress:8080/wmts – XML getcapabilities response

The app also features a tile details view of each tile service. That includes data from the metadata table and the URL’s and TileJSON

The app can serve data to other apps or desktop/laptop GIS mapping software on the network. ArcMap and ArcGIS Pro can access it via OGC WMTS.

Other mapping clients or apps can use the Standard XYZ Tile Server URL (like : http://ipaddress:8080/getGPKGRasterTile/name/{z}/{x}/{y}.png or http://ipaddress:8080/getMBTilesRasterTile/name/{z}/{x}/{y}.png

The Map is accessible on the same device (phone/tablet) or from any device/computer on the network. The Map supports digitizing/drawing, has OSM vector tile basemaps with a style picker, raster basemap selector, supports adding mapping service URL’s like Raster Tiles, Vector Tiles, WMS and others.The map offers in-app dynamic vector tiling of loaded vector data for optimized handling of large data.
Digitize and Draw/Create data and perform Analysis. Tools like Measure distance and area, show coordinates in multiple formats.

The app is perfect for sharing data among devices so one device loads all the map tiles and nearby devices can stream it. This could be in response to a natural disaster or other event and a mobile command center is setup and this becomes the map server for sharing data.

GeoPackage Raster Tiles should only be 3857 Spherical Web Mercator /Auxillary Web Sphere Spatial Reference System/Projection. Test at your own risk support for others.

MBTILES must have the required tiles table or view and metadata table and should follow 1.2 or 1.3 specification.
Encrypted SQLite Databases (SQLCipher or other approaches ) are NOT supported.

We’ve tested the tile server with both web and desktop mapping software (QGIS Desktop, Global Mapper, UDIG, ESRI ArcMap, ESRI ArcGIS Pro, GeoMedia, Autodesk AutoCAD Map, Manifold, MapInfo, Kongsberg Geospatial Mapping Engine(s), GRASS, and others.)
