Just thinking, but wouldn't it be nice to have ogrbuildvrt tool that would
take list of OGR supported layers and outputs a simple vrt with one union
layer like the one in your example?
There is this script,
https://svn.osgeo.org/gdal/trunk/gdal/swig/python/samples/ogr2vrt.py,
with details
GDAL reads EXIF data and you can grab that output and then send it
into an OGR output. I used to have a bash script that did that, but
then I found there were some tricky things to overcome and found that
GpsPrune is really good at this.

I'm using gdalwarp but I'm getting that blank area in the bottom of
my
image. When I try to mosaic (or visualize) with other tile (also
reprojected
with gdal) I get this area that was not suppose to have. Any idea how
to
avoid this?
Thanks

Ahmet,
You can also change geometry type, it is also an option with
ogr2ogr [2], -nlt. I've only used -nlt to promote to multi-geometry.

What is the command that you tried? If you can construct the proper
proj4 format, it should work for ogr. Exactly matching the string in PostGIS
may not work and you may get a new number like 32,000 for a new SRID that was
added in PostGIS. This slightly older thread
Jon,
gdaltransform does some of this. It looks to do 4 corners you would
need to do it four times or list the coordinate pairs on four lines and get
four lines of output back. There might be a clever way to take the output of
gdalinfo as input into gdaltransform saving you some
I tried compiling the FileGDB OGR driver on ubuntu 8.04 and got a few
errors. On the first step I got:

This is an informational report only, there are not problems in trunk.
Using 1.8.0 from OSGeo4W on XP, I made a mosaic of about 1200 uncompressed tifs
totally 80G.
gdalbuildvrt mosaic.vrt *.tif
Then gdal_translated that to a compressed tif of about 8G
gdal_translate mosaic.vrt
I reviewed this a little further. I was mistaken in my first report,
the field RDSRCDATE was created as DATE (as opposed to DateTime) and
populated with null.
I had mistakenly checked and reported on the field CONST_DATE which is
created as an Integer and populated with null. (I don't know if

Could you also try with the -stable builds (based on 1.8 branch) from

I tested the driver on just one FileGDB which included a date

Here is what I did and successfully got the data. The date field was

Is it possible to use vsizip and vsicurl on a password protected ftp site?
Something like this command with user and password passed somehow:
ogrinfo -ro -al -so
/vsizip/vsicurl/ftp://example.com/foldername/file.zip/example.shp
I rather hopefully tried some switches, -user:user

Alexander,
Not sure if it meets you situation, but there is a command line utility
with similar functionality, gdallocationinfo,

I apologize if this question has been posted previously, but I haven't yet

Looking at EPSG:26912 on spatial reference,
http://spatialreference.org/ref/epsg/26912/ and your longitude coordinates
(74-76 East, no less) makes it questionable if 26912 is an appropriate
projection. That projection looks valid for western Mexico, and midwestern
US/CA. You

There are a lot of NAD83 UTM projection zones. You need to chose the
proper one. Without learning a fair amount about datums, projections, and the
area where you are working, you may be best looking on wikipedia and spatial
reference to guess a UTM zone that matches your general

Some of the options (I didn't test all) introduced with version 1.8.0

You could try gdalbuildvrt, then gdalwarp that with -of VRT, then tile it
how you like with gdal_translate. I think that gdal_retile.py has some options
to do what you want as well.
I think that the slivers are probably because the projections have
different angles of
Frank,
This is a helpful new utility.
I read the documentation and tried it out. Using gdallocationinfo to find the
elevation at a given lat/long location seems like a reasonable use. It may be
desirable to input and output an ogr layer rather than a single point. For
