Posted - 04/12/2023 : 13:53:44 I am struggling with geo-calibration of orienteering maps to be used in Garmin 66st. The basic maps were made georeferenced. Most often the KMZ-files do not work. What is the best map parameters.
I use OKmap with 3-5 georeference points. The coordinates I find in Google Earth.
EARLIER RECOMMENDATION I have earlier been recommended Area ETRS89 / KP89 Zealand / UTM zone N32
GOOGLE EARTH I aligned a map in Google Earth. Google saved it as Datum: 6326 - World Geodetic System 1984 ensemble Prime meridian: 8901 - Greenwich (0°) Ellipsoid: 7030 - WGS 84 Unit of measure: 9001 - m Map projection CRS: 3857 - WGS 84 / Pseudo-Mercator Map projection: 1024 - Popular Visualisation Pseudo Mercator
I HAVE MADE A WORKABLE FILE IN OKMAP WITH One pojection which made a workable Gramin KMZ file is Datum: 6258 - European Terrestrial Reference System 1989 ensemble Prime meridian: 8901 - Greenwich (0°) Ellipsoid: 7019 - GRS 1980 Unit of measure: 9001 - m Map projection CRS: 2197 - ETRS89 / Kp2000 Zealand Map projection: 9807 - Transverse Mercator
I am ignorant and do not understand the settings. I just want a setting so I can georeference a map in OKmap.
Posted - 04/12/2023 : 14:22:25 Hi Ivar, please send me the entire map at info@okmap.org. I'll try to do a calibration that works well and generates a good KMZ. Are you sure that the correct projection is CRS 2197?
