Read full description

Geospatial engineering calculations for surveyors and land surveying professionals. Record, stake out and measure areas with GPS in the field; run high-precision coordinate transformations at the office. GPS MODULES ■ Detailing with GPS — record positions from your device's GPS sensor in ED50 and ITRF96, in 3- and 6-degree zones. ■ Stakeout with GPS — navigate to a target coordinate with compass and map guidance. ■ Area Calculate with GPS — walk the boundary to compute area and perimeter. ■ Open Project with GPS — view your DXF, Shapefile and KML drawings over satellite imagery and plot your points on top. CALCULATION MODULES ■ Bearing and distance, angle and distance, polar stakeout ■ Side point, waypoint, station and offset calculation ■ Simple curve calculation ■ 2D coordinate transformation — similarity transformation from two common points ■ WGS84 ↔ UTM and WGS84 ↔ ED50 UTM transformations ■ Official tolerance calculation ■ Degree conversion (degrees, gradians, radians) COORDINATE SYSTEMS ■ Türkiye: ITRF96 and ED50, in 3- and 6-degree zones ■ Global: search and use thousands of systems from the EPSG dataset ■ When opening a Shapefile, the coordinate system is detected automatically from the PRJ file DATA EXCHANGE ■ Import: CSV, DXF, Shapefile, KML/KMZ ■ Export: CSV, DXF, Shapefile (ZIP), KML/KMZ and text report ■ Share your projects by message, e-mail or cloud storage DEVICES AND LANGUAGES ■ iPhone and iPad — full resolution and landscape use on iPad ■ 12 languages: Turkish, English, German, French, Spanish, Italian, Portuguese, Russian, Arabic, Japanese, Korean, Chinese ■ Right-to-left layout support, including Arabic ABOUT ACCURACY All transformations performed by the app are high-precision calculations. However, the accuracy of the result is limited by the accuracy of the WGS84 geographic coordinate your device receives from the satellites: a transformation cannot produce an output more precise than its input. Today, neither handheld GPS units nor the GPS sensors in mobile devices can deliver sub-metre positions directly from satellites. For this reason, Kocaman Pro is recommended for general positioning work rather than high-precision positioning work.
