Coordinates are often needed for ground control points (GCP) with the objective to georeference remote sensing data or scanned maps without graticule. Google maps can be used as one source for registering point coordinates.
Import highly accurate DGPS points stored in a ASCII CSV file
Click Add delimeted Text File. Select the input file GBdata\GBData\GNSS\Festpunkte_Forstbotanischer_Garten.csv. Define the X field: East and Y field North. OK. Specify the coordinate reference system ETRS / UTM zone 32N. Search for the EPSG code: 25832.
