LandMate: GPS & Measure Area

LandMate makes it easy to measure, locate, and navigate field positions directly from your phone.
Measure land area, perimeter, and distance on an interactive map with a precise crosshair interface. Mark locations manually or record your position using built-in GPS.
Designed for practical outdoor use - from estimating field sizes to saving points, navigating to coordinates, and sharing professional location data.

NEW IN LANDMATE PRO (SUBSCRIPTION UNLOCK)
Bridge the gap between mobile field tracking and your desktop CAD or GIS workspace.
• NASA SRTM Terrain Modeling: Access global 30-meter precision Shuttle Radar Topography Mission data directly inside your app.
• Dual Elevation Profile Charts: Compare raw phone GPS height and true bare-earth terrain data side-by-side on an interactive graph to immediately identify river crossings, structural heights, and slope adjustments.
• Smart Auto-Download Caching: Plan your project ahead of time. The app streams and stores required elevation data chunks automatically on the first request for 100% autonomous, offline field execution.

KEY FEATURES
• Measure Area & Distance: Place points on the map to calculate open routes or closed land boundaries automatically.
• Precise Crosshair Placement: Pan and position the map beneath a fixed reticle for clear point placement without obstruction from your finger.
• GNSS/GPS Point Capture: Record current location data using device GPS, utilizing multi-sample averaging for consistent point storage.
• Locate & Navigate: Select saved coordinates to find points on the ground. Track distance and direction as you move.
• Multiple Coordinate Formats: View and share coordinates in Latitude/Longitude, UTM (with manual zone configuration), and MGRS formats.
• Save & Organize: Save measurement records, boundaries, and routes for later reference.
• Export & Share: Export field data outside the app in PDF, CSV, DXF (CAD-ready), and 100% QGIS-compatible GeoJSON formats.
DESIGNED FOR FIELD USE
Useful for landowners, farmers, property managers, outdoor enthusiasts, and professional GIS technicians, surveyors, and civil engineering teams needing straightforward mobile data collection.
ACCURACY & DISCLAIMER
GPS accuracy depends on mobile hardware capabilities, satellite visibility, and environmental factors. Landmate is intended for general measurement, mapping, and field location estimation. It is not a replacement for professional cadastral or official boundary legal surveys.
