The Global CRS option in Kocaman Pro lets you use more than 4,800 coordinate systems from the EPSG dataset, alongside the ITRF96, ED50 and WGS84 systems used in Türkiye. The feature arrived in version 2.7 on Android and has been on iOS since version 3.5.
How it works
- Coordinate systems are searched for and selected from the EPSG dataset (v12.054).
- In the GPS modules, the device’s WGS84 position is converted to the selected system in real time.
- The EPSG code of the selected system is shown on the project and stakeout screens.
- When you open a shapefile, its coordinate system is detected from the PRJ file.
- Transformations run on the device; the EPSG dataset is built into the app.
Android 3.5 also brought accuracy fixes for global (EPSG) coordinate systems. Results are limited by the accuracy of your device’s GPS position; phones do not deliver centimeter-level accuracy.
