Offline Maps gives you a fully interactive map viewer that works without any internet connection. Maps are downloaded by region ahead of time and served entirely from your N.O.M.A.D. server, so you can navigate, search, and zoom with no connectivity required. The feature is powered by ProtoMaps, which stores map data in the efficient PMTiles format.

​
How to access

Click Maps from the Command Center home screen, or navigate directly to /maps.

​
Using the map

Drag and zoom

Click and drag to pan the map. Use the scroll wheel or pinch gesture to zoom in and out.

Location search

Use the search bar to find a specific address, city, or point of interest within your downloaded regions.
If the map shows a gray or blank area, that region has not been downloaded yet. See How to download maps below.

How to download maps

Map regions are managed from the Maps Manager in Settings. You can download as many regions as your storage allows.
1

Open the Maps Manager

Go to Settings → Maps Manager.
2

Select regions

Browse the available regions and select the ones you need. Regions are organized geographically (for example, by state or territory).
3

Start the download

Click Download. Downloads run in the background — you can continue using other features while they complete.
4

Open the Maps viewer

Once the download finishes, navigate to /maps. The newly downloaded region will be available immediately.
Download your primary region and its neighboring regions. If you’re near a state or national border, having adjacent coverage ensures you’re not left without a map when you cross it.

​
Storage requirements

Map files use the PMTiles format and vary in size by region. As a reference point, US state maps are approximately 2–3 GB each. Smaller or less-detailed regions will be smaller.
Check your available storage in Settings → System before downloading large regions. Map files can be deleted from the Maps Manager to free up space.

​
How it works

Offline Maps uses ProtoMaps technology. Map data is stored locally in the PMTiles format — a single-file archive that supports efficient random-access reads, so the viewer can load only the tiles needed for the current viewport rather than the entire file. This makes it practical to store high-detail regional maps in a reasonable amount of space. Base map assets (fonts, sprites, and styles) are automatically downloaded and cached by N.O.M.A.D. the first time you open the Maps viewer. These are required for the map to render properly.
