[gdal-dev] gdalbuildvrt could not use worldfile

Hello list,


I'm a beginner with gdal and use Linux Debian testing as the OS.


I like to create a .vrt file to use a map.

The map comes with a worldfile .tfw:

1.2700000000
0.0000000000
0.0000000000
-1.2700000000
376279.1000000000
5679613.9199999999


If I try to build the .vrt by using


gdalbuildvrt map_1.vrt map_1.tif


The .vrt is present now.


But I can't use it in a mapviewer, which gives out a message, that the 
georeferences are not present.
