KEY FEATURES OF TERRA GIS MOBILE:

1. SPATIAL DATA COLLECTION & PRECISION DIGITIZING
• Digitize Points, Polylines, and Polygons seamlessly on interactive maps.
• Smart Vertex Snapping: Automatically snap nodes and edges to existing points for topology-clean geometry.
• Dynamic Attribute Forms: Collect field survey attributes, layer categories, documentation photos, and technical notes.
• Automatic Area & Distance Calculation: Instant real-time perimeter, area (sqm, hectares, acres), and length measurements.

2. CUSTOM BASEMAPS & WEBGIS INTEGRATION (ONLINE & OFFLINE)
• ArcGIS REST Server support (MapServer & ImageServer - Tiled & Export).
• OGC WMS (Web Map Service) & WMTS (Web Map Tile Service) with automated capabilities inspection.
• Offline MBTiles raster support for surveying in remote offline areas with zero cellular reception.
• Basemap library including Google Satellite, ArcGIS World Imagery, OpenStreetMap, and Topographic contours with real-time layer opacity sliders.

3. FIELD GPS TRACK RECORDING & NAVIGATION
• Continuous GPS Breadcrumb Tracking to record survey paths and parcel perimeter walks.
• Background Tracking Support: Uninterrupted GPS logging even when your phone screen is off or locked to preserve battery outdoors.
• Keep Screen On (Wakelock) option during field survey sessions.
• One-tap True North Compass reset and Map Orientation Lock to prevent unintended map rotation during pinch-to-zoom.

4. GEOTAGGED CAMERA & SURVEY WATERMARK
• Capture field photo evidence stamped with precise GPS coordinates (Lat/Lon).
• Automated watermarking including timestamp, elevation, project metadata, and reverse geocoded address.
• Photos are automatically linked to their respective spatial features.

5. LAYER MANAGEMENT, IMPORT & EXPORT
• Multi-layer management with custom styling, stroke colors, fill opacity, and symbology.
• Export and share your survey datasets in standard GIS formats:
- ESRI Shapefile (SHP in ZIP)
- GeoJSON
- Google Earth KML / KMZ
- CSV Spreadsheet with coordinates
• Coordinate reference systems support: WGS84 (EPSG:4326) and Web Mercator (EPSG:3857).
