Hrmm, that is sort of unfortunate. I have set up a tiling algorithm to read in
tiles at a time of imagery data, which is already slow-ish, even doing it it
with threads. Having to do a whole new read of the entire image at once (since
it doesnt seem CreateCopy takes any block parameters) would b

Hi,
i would like to use gdalwarp to solve a problem we have. Like i am a very
new user of gdal I don't know, if gdalwarp really can solve the problem, but
I hope so. The problem that we have are a kind of "disformed" images in its
positions. The images have several shifts in various directions. Bu
Likely Quickbird_06m10.tif has more or less bands than the previous
files, or band bit depth is different.
That was it, thanks.
For some reason although they were all created from the same source and
process (arcmap > export > selected area) some images are 8bit RGB and
others 16bit grey
Matt,
Likely Quickbird_06m10.tif has more or less bands than the previous
files, or band bit depth is different. For example, don't try to
include a 1 band 16-bit (e.g. gray scale) tiff in a VRT of 3 band, 8
bits each (e.g. RGB color) tiffs.
What does gdalinfo say about this file (and

Brian,
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 sugges

Alex,
In fact, with a quick check I see I have added a Trim() method to the

Sorry to spam the list, but I am wondering if this is related to the threading

Another question: To get several fields from the file's metadata, is it
better to use GetMetadata() and then search within the array for the fields,
or use GetMeta
Hi Everyone,
I was wondering if there are any help files or guides on how to define a custom
coordinate system to use with the ogr2ogr.exe utility. I am trying to use it
to load a shapefile into a PostGIS database. The shapefile is in a custom
Minnesota County coordinate system. When I try to
I am afraid I won't be able to post a screenshot, or the original image that is
causing this issue.
I will also note, occaisionally the image fails to load at all, and I get a
dump like this:

ERROR 1: opj_read_header() failed
ERROR 1: IReadBlo
