Hi all,
I'm having some trouble using gdalwarp to mosaic ArcInfo Binary Grid files
to vrt.
Here is what I want to do and works in .tif. I mosaic the three grids be... to
test2.tif:
gdalwarp -t_srs "EPSG:2913" -s_srs "EPSG:2994" -srcnodata "0 0 0" -dstnodata "0
0 0" -of GTIFF be44123g8b be44123g8c be44123g8a test2.tif
Creating output file that is 11039P x 15191L.
Processing input file be44123g8b.
0...10...20...30...40...50...60...70...80...90...100 - done.
Processing input file be44123g8c.
0...10...20...30...40...50...60...70...80...90...100 - done.
Processing input file be44123g8a.
0...10...20...30...40...50...60...70...80...90...100 - done.
test2.tif looks fine with gdalinfo and in OpenEV.
That works how I want. However, I have many more than 3 grids and can't create
an output file that large. So I use vrt which has been very useful to me in
the past:
gdalwarp -t_srs "EPSG:2913" -s_srs "EPSG:2994" -srcnodata "0 0 0" -dstnodata "0
0 0" -of VRT be44123g8b be44123g8c be44123g8a test2.vrt
Creating output file that is 11039P x 15191L.
Processing input file be44123g8b.
test2.vrt looks fine with gdalinfo but not in OpenEv. Also, when I look in the
.vrt file itself, I only see one reference to the 1 grid and not to the other 2
grids:
<SourceDataset relativeToVRT="1">be44123g8b</SourceDataset>
I also notice that when processing to tif each of the 3 grids are listed. When
processing to .vrt only 1 grid is listed.
I read up on vrt here, http://www.gdal.org/gdal_vrttut.html to try and manually
create/edit a vrt file but my preliminary tries weren't successful.
Let me know if you need any additional information on this or have any ideas.
Thanks, Eli
