About GeoNames Map Explorer
This app is NOT affiliated with the U.S. Government
The app was originally designed and sold exclusively to US Government personnel via the NGA GEOINT App Store and now is publically available.
We developed this app based on vendor opportunity packages (GeoNames, GeoCognizant, Talking Map, and several others) as well as many conversations and feedback from the National Geospatial-Intelligence Agency and members of the US Dept. of Defense and other Government Agencies.
We are building custom white-labeled versions of this app as well as selling the source code. Contact us to learn more.The app works immediately after install with internet access and works offline by downloading an area of interest first. The map, search, and audio playback work with data on Tech Maven Geospatial’s server.

What is GeoNames?
The US Government (NGA – Foreign GeoNames GNS and USGS – BGN Domestic GNIS) produces the GeoNames data that includes Place Names, point of interest features, and geographic features.
This database has over 18 Million points!

Hysography – Land features
