FIELD DATA COLLECTION • Create geological observations with notes, coordinates and photographs • Record Rock, Soil, Stream and Other samples • Manage drillhole collar, survey, lithology and assay data • Add project-specific custom fields MAP-BASED WORKFLOWS • Place objects using your current GPS position or the map center • Create points, lines, polygons, rectangles, circles and text • Record geological units, structural lines, strike and dip data • Measure distance, bearing, area and perimeter • Create and review geological sections COORDINATES • WGS84 geographic coordinates • UTM based on WGS84 • UTM based on ED50 for supported zones • MGRS coordinate display TRACK RECORDING Record field routes and review track duration, distance and point count. With the required iOS permission, recording can continue while the device is locked.
