TopoXY: Topo Survey & CRS
EPSG, UTM & terrain for EU
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
This new version adds 6-country CRS routing: Romania, Poland, Czechia, Slovakia, Italy & Germany. Engineering-grade conversion, offline-ready. Try free.
Engineering-grade coordinate conversion and terrain analysis for surveyors, civil engineers, and GIS professionals working across six EU countries.
TopoXY Tools converts between WGS 84 and national coordinate reference systems on device, with documented accuracy per country:
- Romania - Stereo 70 (EPSG:31700), sub-metre precision
- Poland - PUWG 1992 (EPSG:2180), sub-centimetre
- Czechia & Slovakia - S-JTSK Krovak (EPSG:5514), sub-centimetre
- Italy - Gauss-Boaga zone 2 (EPSG:3004), 1-3 m, with UTM 32N / 33N alternates
- Germany - ETRS89 / UTM 32N (EPSG:25832), sub-centimetre
Conversion runs fully offline so fieldwork keeps moving when signal drops.
TERRAIN AND MAP FEATURES
- Elevation profiles powered by Mapbox terrain data
- Slope and aspect analysis for any waypoint or route
- Contour line overlays for site reconnaissance
- Distance to nearest river, road, or peak
- Romania-only: ANCPI cadastre parcels and national ortophoto layer
- Export waypoints and routes for downstream CAD or GIS workflows
WHO IT IS FOR
Licensed land surveyors, cadastral teams, civil engineering crews, infrastructure planners, geodesy students, and GIS analysts who need a fast field companion alongside total stations, GNSS receivers, and desktop CAD. TopoXY Tools is a professional reference and planning aid, not a replacement for a licensed surveyor or a calibrated RTK rover. Always confirm cadastral results against the official national register before any legal filing.
