Real survey data from your pocket.
Standard formats, real coordinates and numbers you can check. SpeleoMap's exports open in the tools your workflow already uses, with no conversion step.

Georeferenced coordinates
Georeferenced, or not at all.
With the entrance GPS and true north locked, the cave centerline exports in WGS84 as KML for Google Earth and GeoJSON for QGIS and ArcGIS. Lines without full calibration are left out, never guessed.
Coordinates the way your team reads them.
Decimal degrees, DMS, UTM or MGRS on the map, on pins and in shares. Hike Lines and waypoints go out as GPX and KML.
Survey numbers and formats
Every number in the CSV.
The station table carries each station's position, the leg's slant, horizontal and vertical distance, azimuth and inclination, and running totals for path distance, depth and elevation gain and loss. Exported in your units; bundle CSVs use meters and radians.
Survey formats.
Survex .svx and Therion .th, with legs, splays, LRUD and declination. Readings never taken are written as missing, never as zero. Import works the other way too: .svx, compiled .3d and .th come in as Cave Lines, and loops report their misclosure.
Meshes and the entrance fix
Point clouds and meshes.
iPhone Pro scans export as OBJ, PLY and USDZ for CloudCompare, MeshLab and Blender. Each scan keeps its anchor to the survey, so position and heading come with it.
Know how the fix was taken.
The entrance fix is averaged over time, and a fix from an external Bluetooth GPS receiver is recorded as such. A Pro iPhone's own averaged fix is usually within a few meters.
