Tile and WMS endpoints
Paste a {z}/{x}/{y} template or a WMS GetMap URL. The layer wizard probes it, works out the zoom range and projection, and registers it.
Layer library · 200+ sources · 14 categories
Every layer. Everywhere. And the license to prove it.
Most apps ship a handful of basemaps and call the rest "premium". NavTrax ships a catalog: 200-plus registered sources, grouped into fourteen categories, each carrying its provider, attribution, license, update frequency and coverage envelope. You can read all of that before you download a single tile.
01 / The catalog
Fourteen categories, because the ground is not one thing.
A slope-angle raster answers a different question than a bathymetric chart, which answers a different question than a wildfire perimeter. The category structure exists so the right question is one tap away rather than buried in a list of two hundred names.

02 / What a layer carries
A source you cannot audit is a source you should not trust.
Every entry in the catalog is a full record, not a name and a URL. This is what the app stores and shows for each one.
- Provider
- The organization that publishes the data — NASA, NOAA, ESA, Copernicus, USGS, FEMA, WRI, Esri, CARTO, OpenStreetMap and others.
- Attribution
- The exact credit string, rendered on screen whenever the layer is visible. Not buried in a settings page.
- License
- ODbL, CC-BY, CC-BY-SA, public domain, NASA Open Data, or a named commercial term of service.
- Update frequency
- Continuous, 5–10 minutes, hourly, daily, weekly, annual, or explicitly static with the vintage year.
- Coverage
- Global, regional or national, with the actual latitude bounds where they matter — SRTM stops at 60°N.
- Data type
- Vector, raster, WMS, API or GeoJSON. Determines how it caches and how it composites.
- Endpoint
- The tile or service URL, where the license permits publishing it.
03 / Pipeline
From a published source to a tile on a dark phone.
The path a layer takes from a public endpoint to a rendered pixel in a valley with no signal. Drag a node to rearrange it; hover to isolate its dependencies.
04 / Custom layers
Your data is a first-class layer.
Bring a tile URL, a WMS endpoint, a GeoJSON file or a shapefile export. It joins the catalog with the same metadata fields, the same offline behavior and the same attribution surface as anything NASA publishes.
Vector uploads
GeoJSON, KML and shapefile exports become styled vector layers with attribute-driven symbology.
Organization layers
On Enterprise, a layer published by an organization appears for every member automatically, scoped by role — so a cut-block boundary or a lease outline reaches the whole crew without anybody emailing a file.
Community layers
Users can publish a layer to the community catalog. Moderated, attributed, and clearly labeled as community-sourced rather than authoritative.
The layer library is on the Free tier. The offline scale is what you pay for.
Every source in the catalog renders on every tier. Free gives you three offline regions to prove it works where you go.
