<br>
<br>
I'm a beginner with gdal and use Linux Debian testing as the OS.<br>
<br>
<br>
I like to create a .vrt file to use a map.<br>
<br>
The map comes with a worldfile .tfw:<br>
<br>
1.2700000000<br>
0.0000000000<br>
0.0000000000<br>
-1.2700000000<br>
376279.1000000000<br>
5679613.9199999999<br>
<br>
<br>
If I try to build the .vrt by using<br>
<br>
<br>
gdalbuildvrt map_1.vrt map_1.tif<br>
<br>
<br>
The .vrt is present now.<br>
<br>
<br>
But I can't use it in a mapviewer, which gives out a message, that the <br>
georeferences are not present.<br>
<br>
<br>
gdalinfo map_1.tif<br>
Driver: GTiff/GeoTIFF<br>
