That did the trick. I had already tried "+proj=utm +zone=33 +ellps=WGS84 +datum=WGS84 +units=km +no_defs", without success, but I just needed a couple of minor changes. First of all, my example I got my signs mixed up, so easting/northing should be 75000 and -645. I also had to add the shifting UTM33 uses, so the correct easting is 575000. Finally, by adding the scale factor of 0.9996, the image positioned itself exactly where I want it. So, my final projection block is: PROJECTION +proj=tmerc +lat_0=0.0 +lon_0=15 +x_0=575000 +y_0=-645 +a=6378137.0 +b=6356752.3141403 +datum=WGS84 +k_0=0.9996 +units=km END This is a workaround I can live with.

Re: [mapserver-users] Georeferencing a raster without worldfile
Hi, One alternative could be to read your png files through GDAL virtual raster http://www.gdal.org/gdal_vrttut.html Problem that you should solve is how to inject the file name into the SourceFilename element utm.tif But the wms_extent metadata seems quite promising to me. You could then change the file with %variable% in DATA. How did you test that it has no effect? -Jukka Rahkonen- Lähettäjä: mapserver-users [mailto:mapserver-users-boun...@lists.osgeo.org] Puolesta Richard Greenwood Lähetetty: 1. joulukuuta 2017 19:56 Vastaanottaja: Trond Michelsen <trondmm-mapserver+2...@crusaders.no> Kopio: Mapserver <mapserver-users@lists.osgeo.org> Aihe: Re: [mapserver-users] Georeferencing a raster without worldfile On Fri, Dec 1, 2017 at 9:50 AM, Trond Michelsen <trondmm-mapserver+2...@crusaders.no<mailto:trondmm-mapserver+2...@crusaders.no>> wrote: Thank you for the suggestion.

If these are .tif files, can you write the georeference info to internal metadata as a way to avoid a .tfw file? -Original Message- From: mapserver-users [mailto:mapserver-users-boun...@lists.osgeo.org] On Behalf Of Trond Michelsen Sent: Friday, December 01, 2017 10:19 AM To: Mapserver <mapserver-users@lists.osgeo.org> Subject: [mapserver-users] Georeferencing a raster without worldfile Hi.
