Janez T 30bd3315aa Add WMS overlays for hiking trails, main roads, house numbers, fire hazard zones, historical fires, firebreaks, Kras fire zones, place names, and municipality borders 
- Updated localization files for German, English, Spanish, French, Croatian, Italian, and Slovenian to include new overlay labels.
- Implemented new WMS layers in the map provider and map tab for displaying hiking trails, main roads, house numbers, fire hazard zones, historical fires, firebreaks, Kras fire zones, place names, and municipality borders.
- Added toggle functionality for each new overlay in the map provider.
- Enhanced the map tab UI to include checkboxes for the new overlays, allowing users to enable or disable them.
- Integrated the new WMS layers into the map rendering logic.

RECOMMENDED IMPLEMENTATION PLAN

Phase 1: Critical Overlays (Immediate)

Add these layers as toggleable overlays in the Map Options screen:

  1. Forest Roads (gozdne_ceste) - PNG, transparent

    • Critical for vehicle access in remote areas

  2. Hiking/Mountain Trails (KGI_LINIJE_PLANINSKE_POTI_G) - PNG, transparent

    • Common search areas for lost hikers

  3. Fire Hazard Zones (pozarna_ogrozenost) - PNG, transparent

    • Safety planning, risk assessment

  4. Settlements (NEP_RPE_NASELJA) - PNG, transparent

    • Populated areas, staging areas

  5. Municipalities (NEP_RPE_OBCINE) - PNG, transparent

    • Administrative boundaries

Phase 2: Additional Useful Layers

  1. Geographic Names (zemljepisna_imena)
  2. Forest Fires Historical (gozdni_pozari)
  3. Protected Areas (zavarovana_obmocja_poligoni)
  4. Topographic Map (DTK25) - Alternative base layer
  5. Infrared Imagery (DOF_IR) - Alternative base layer

Phase 3: Specialized Layers (On Demand)

  1. Windthrow/Disaster Areas (for post-disaster operations)
  2. Recreation/Tourism Areas (for prioritizing search areas)
  3. Protection Forests (avalanche/erosion hazard awareness)

TECHNICAL NOTES

CRS Compatibility

  • All layers from prostor.zgs.gov.si support EPSG:3794 (Slovenian National Grid)
  • The app already has the correct CRS implementation in lib/utils/slovenian_crs.dart

Recommended Formats

  • Base Layers: JPEG (better compression for imagery)
  • Overlays: PNG with transparency=true (for stacking)

Caching Strategy

  • All layers should use the existing FMTC caching infrastructure
  • 30-day validity is appropriate for most layers
  • Consider longer validity for static layers (administrative boundaries)

Performance Considerations

  • Limit active overlays to 3-4 simultaneously to avoid performance issues
  • Use appropriate zoom level restrictions (some layers only useful at close zoom)
  • Consider pre-downloading critical layers for offline SAR operations
