Add live GPS-tracked radiation map to dashboard

[Copilot]

Implements interactive map visualization of radiation readings with GPS coordinates, allowing spatial analysis of dose/count rate data during mobile surveys.

Implementation

MapCardView - Custom view encapsulating Google Maps with radiation-specific overlays

• Color-coded circle markers (green→yellow→red gradient by normalized value)
• Metric selector: dose rate (μSv/h) or count rate (cps)
• Dynamic legend with auto-scaling min/max bounds
• Per-device reading isolation (up to 1000 readings cached)

Data Layer - Extended Prefs with GPS-coordinate storage

data class MapReading(
    val latitude: Double,
    val longitude: Double,
    val uSvPerHour: Float,
    val cps: Float,
    val timestampMs: Long
)

Serialized as: timestamp,lat,lon,dose,cps semicolon-separated in SharedPreferences

Integration - MainActivity UI loop polls FusedLocationProvider on each reading, stores MapReading atomically, updates map markers

Styling - Dark map theme JSON (map_style_dark.json) matches app palette (#1A1A1E backgrounds, #2A2A2E borders)

Dependencies

• play-services-maps:18.2.0
• play-services-location:21.1.0

Requires ACCESS_FINE_LOCATION and ACCESS_COARSE_LOCATION permissions. Includes development Maps API key (restrict for production).

Layout

Map card inserted in dashboard between CPS chart and isotope panel. 300dp fixed height, full width, standard 12dp card padding.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Original prompt

Go code the live map view on dashboard. it's in the issues everything you need. all the details are in the issues so go pull that issue. create a branch code it all out.
