<div>Hi everyone,</div>
<div>I am getting this weird error when I try to convert a vrt to a tif. </div>
<div> </div>
<div>Some context: We are tiling a set of tifs(in a list file). First we generate a vrt from the list. Then we assign a projection on the generated vrt using gdaltranslate. We then clip the output using gdalwarp applying a clipping at the same time to the desired
BBOX(This is achieved using the –te option). In the warp operation we also specify the target SRS(using the –t_srs option). Lastly we tile using our customized gdal_retile.py. All is fine with the projection and clipping, but the resultant tiles are empty-no
data just white images.</div>
<div> </div>
<div>So I tried to backtrack my steps, to check at what point is the data being lost. Generation of the VRT works fine. However, performing gdaltranslate to assign the source SRS on the VRT result into this error:</div>
<div> </div>
<div style="padding-left:35pt">bash-2.05$ gdal_translate -of GTiff ffm_dtk200_wdd.vrt test.tif</div>

<div>I tried to also convert to AAIGrid format, thinking that something is wrong converting to Tiff, but also got this error:</div>

<div> </div>
<div>Other tiling jobs following a similar method, with different source data works fine though. Could the problem be with the data? If so how comes it worked before?</div>
