Datumark: Survey Camera

iOS app by Shadowfetch · App Store ID 6792598709 · iOS

Datumark turns your iPhone into a precise field-survey instrument. Capture coordinate-stamped photos, measure distances and areas on site, convert between coordinate systems, and export clean data files — entirely on device. No account. No cloud. No tracking. Your position data never leaves your phone.

Built for surveyors, construction and utility crews, field researchers, inspectors, geocachers and anyone who needs trustworthy position data where there is no signal.

Gps Field Camera

• Burn coordinates, bearing, altitude, datum and magnetic declination directly into each photo
• Choose the coordinate readout: latitude/longitude, UTM or MGRS
• Writes standard EXIF GPS geotags into every image
• On a device without a usable camera it still records a clean coordinate field card, so nothing is lost

Coordinate Converter

• Convert any position across latitude/longitude, UTM and MGRS
• Switch geodetic datums — WGS 84, NAD 83, NAD 27, ED50, OSGB 1936, Tokyo, Pulkovo 1942 — with full 7-parameter Helmert transforms
• Degrees / minutes / seconds, degrees-minutes, or decimal degrees
• Grid convergence and point-scale factor for every location
• Enter coordinates by hand or read your live GPS fix

On-Site Measurement

• Distance along a path and enclosed area, computed on the reference ellipsoid (Vincenty geodesics)
• Metric or imperial: metres, kilometres, feet, miles, hectares, acres
• Log waypoints and record tracks in the field

Magnetic Declination & Elevation
