Authoritative place-name intelligence
Points of interest and place names from the U.S. Government — NGA Foreign GeoNames & USGS Domestic GNIS. We update monthly, optimize for mobile, and load into our custom database & API — online and offline.
US Government data
NGA Foreign GeoNames and USGS Domestic GNIS produce the Geographic Names datasets used worldwide for place names, points of interest, and geographic features. Tech Maven processes and optimizes this for handsets — including true offline AOI packages, monthly refreshes, and a custom Geo Request API.
Nine categories
This database has over 18 million points.
In the app
Large, full screens — the same clarity you’d expect from a modern product page.
Display control
Keep the map clean when you need terrain only, then bring names back with one toggle. Choose which feature classes stay visible, and let zoom control how dense the labels get.
Attributes
Tap a place and read the record — official name, feature type, and related attributes — without leaving the map. Confirm a locality, crossing, or installation before you brief or move.
Nine categories
Narrow the map and search to the classes that matter for the mission — from Administrative and Populated Places through Spot features. Turn the rest off and keep focus on the AOI.
Designation codes
Go deeper than the nine classes — airports, border posts, military sites, places of worship, and more. For USA GNIS we standardize to the nine feature classes so domestic search stays consistent.
On-map details
Keep context on screen while you pan. The information box stays tied to the selected GeoNames record so you can compare nearby features without losing the detail pane.
Vicinity queries
Search by name, feature class, and designation — then constrain results from map center so you only see what’s in the current country / vicinity / AOI, not a worldwide dump of lookalikes.
Search by filtering
Combine filters with map-extent search. Popular Spot-class designated searches:
Five sources · 250M POI
Online and offline for your custom AOI — open each source for details and official links.
NGA Foreign GeoNames — authoritative names for overseas operations. Access the government search app:
USGS domestic GNIS for the United States — standardized in-app to the nine feature classes (no separate designated-code lookup for USA).
OpenStreetMap POIs enrich the search stack for amenities and local features — available through the Geo Request API for your AOI, online and offline.
Overture Maps Places adds modern place coverage that merges with GeoNames and OSM for denser POI search in your operating area.
Foursquare POI contributes commercial and venue-style points — part of the combined 250 million POI capacity across all five sources.
