Land Surveyor

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
