For Surveying & Construction Engineers
Terramark stamps every photo with UTM, MGRS, decimal or DMS coordinates plus GPS accuracy — then exports straight into the KML, CSV and GeoJSON formats your GIS software already reads.
For iPhone, iPad and AndroidBuilt For
Record boundary corners and benchmark points with the UTM zone and EPSG code baked into every export — no manual conversion before opening in QGIS or ArcGIS.
Document site progress with a timestamped, geotagged photo trail that holds up as proof of work — organized by project, not scattered across a camera roll.
Switch between Decimal, DMS, UTM and MGRS on the same record — pick the format your next deliverable needs without re-shooting anything.
±m GPS accuracy and true or magnetic compass heading are stamped directly on the photo, not buried in a report you have to cross-reference later.
Old Way vs. Terramark
| Step | Paper notes + camera roll | Terramark |
|---|---|---|
| Recording coordinates | Read off a separate GPS unit, transcribed by hand | Stamped on the photo automatically |
| Format conversion | Manual UTM/decimal conversion before GIS import | UTM zone + EPSG code included in every export |
| Organizing by site | Sorted manually by folder or date | Records grouped by project automatically |
| Office handoff | Retype notes, attach photos separately | One KMZ, CSV, GeoJSON or PDF export, ready to send |
Yes — CSV and GeoJSON exports include the UTM zone and EPSG code for each record's location, so they import directly without manual reprojection.
Yes, each record can be viewed in Decimal, DMS, UTM or MGRS at any time. The underlying capture doesn't change, only the display and export format.
Terramark stamps true heading when available, falling back to magnetic heading with a visible ≈ warning. Treat it as a field reference, not a substitute for a calibrated total station.
