Hello!
I am trying to import ground control points in epsg:31255 Austria GK Central, but once imported, they are placed at totally wrong poisitions in the map.
File format:
This point should be located somewhere near Enns/Austria, but instead it shows up somewhere in the Adriatic Sea.
If I transform the coordinates into WGS84, the position is correct.
Any help highly appreciated.
Kind regards
Hi Fabian,
you need to use these Import GCP settings:
Then:
What was your file format in settings?
Hello ,
thank you for your response. Of course you’re right, I kept the default setting (degrees). However, the Ground Control Point’s position on the map is still not correct. According to epsg.io (and also to our orthographic map) the position should be a few hundret meters to the east.
The GPS coordinates of the images I imported display correct on the map.
Kind regards
Hi,
it seems that here is no actual espg information in our database. It is possible to solve.
Go to C:\Program Files\Capturing Reality\RealityCapture and open epsg.xml file. Look for your coordinate system there (31255) and delete this:
paramsWKT="PROJCS["MGI_Austria_GK_Central",GEOGCS["GCS_MGI",DATUM["D_MGI",SPHEROID["Bessel_1841",6377397.155,299.1528128]],PRIMEM["Greenwich",0.0],UNIT["Degree",0.0174532925199433]],PROJECTION["Transverse_Mercator"],PARAMETER["False_Easting",0.0],PARAMETER["False_Northing",-5000000.0],PARAMETER["Central_Meridian",13.3333333333333],PARAMETER["Scale_Factor",1.0],PARAMETER["Latitude_Of_Origin",0.0],UNIT["Meter",1.0]]"
after that go to https://epsg.io/31255, copy proj.4 line and paste it instead of
+proj=tmerc +lat_0=0 +lon_0=13.33333333333333 +k=1 +x_0=0 +y_0=-5000000 +datum=hermannskogel +units=m +no_defs
Then save the file, restart the application as is described here
and after import of the GCP it should be on correct position.
Hello ,
thanks a lot!! This worked out for me!
One addition to your posting, in case anyone comes across the same problem (the link is not working): I guess you meant this one: https://support.capturingreality.com/hc/en-us/articles/115001485132-How-and-when-to-reset-all-settings-
