Owner

Add a button (on the bottom sheet and/or compass view) that opens walking directions to the selected shelter in an external maps app.

Implementation

Use an ACTION_VIEW intent with geo: URI: geo:lat,lon?q=lat,lon(Tilfluktsrom - address)
The geo: URI is handled by whatever maps app the user has installed (OsmAnd, Organic Maps, Google Maps, etc.)
OsmAnd and Organic Maps both support offline navigation with geo: intents — this is the ideal pairing for degraded-network scenarios
Do NOT hardcode Google Maps URLs — use the generic geo: scheme
Falls back gracefully if no maps app is installed (show Toast with coordinates to copy)
Add button next to the shelter address in the bottom sheet

Why

In an actual emergency, finding the shelter on the map is only half the problem — you need walking directions to get there. The geo: intent works with offline-capable maps apps (OsmAnd, Organic Maps), which is critical when the network is degraded or down.

Add a button (on the bottom sheet and/or compass view) that opens walking directions to the selected shelter in an external maps app. ## Implementation - Use an `ACTION_VIEW` intent with `geo:` URI: `geo:lat,lon?q=lat,lon(Tilfluktsrom - address)` - The `geo:` URI is handled by whatever maps app the user has installed (OsmAnd, Organic Maps, Google Maps, etc.) - OsmAnd and Organic Maps both support offline navigation with `geo:` intents — this is the ideal pairing for degraded-network scenarios - Do NOT hardcode Google Maps URLs — use the generic `geo:` scheme - Falls back gracefully if no maps app is installed (show Toast with coordinates to copy) - Add button next to the shelter address in the bottom sheet ## Why In an actual emergency, finding the shelter on the map is only half the problem — you need walking directions to get there.
