Land Surveyor — 60 Professional Surveying Tools
The complete toolkit for surveyors, civil and site engineers: centimetre-accurate RTK survey with your own GNSS receiver, coordinate conversion (UTM, DLTM, EPSG), traverse, curves, GPS stakeout, and DXF/CAD export.
RTK SURVEY
• Connect a GNSS/RTK receiver over Bluetooth, USB or Wi-Fi
• Stream NTRIP corrections for centimetre-accurate positioning
• Live solution status — Single, Float, RTK Fixed — with satellites and base distance
• Collect RTK points into jobs, then Measure and Stakeout with your rover
• Works with standard NMEA-0183 / RTCM 3.x receivers, with a built-in setup guide
MAPS & GPS
• APPNEST Maps — tap coordinates, measure distance, area, route
• Live Coordinates — real-time GPS in UTM and spherical
• Measure Points — capture GPS points, export to Excel
• Stakeout Coordinates — navigate to survey points on map
• DLTM Stakeout — stake out Dubai LTM coordinates
• Road Alignment Stations — import CSV, show stations on map
• LandXML Point Query — station, offset, TIN elevation
• KSA Control Points — Saudi Arabia control points on map
• KML Viewer — import and view KML files

Recent changes:
Stability and performance update.
• DXF Viewer is much faster on large drawings — smooth pan and zoom, no more freezing on heavy files.
• Fixed a crash when background GPS tracking started after location permission was turned off.
• Fixed a rare crash when swiping back while a screen was still opening.
• RTK sessions no longer stop if location permission is unavailable — the receiver stays connected.
