I have a process that is stitching together a lot of tif files to
create on big tif.
I am doing:
gdalbuildvrt output.vrt *.tif
gdaltranslate -co COMPRESS=LZW output.vrt final.tif
Any more options that I can throw at gdaltranslate to speed up the translation?
Thanks!
I have a set f tiff files at different zoom levels/resolutions
0.tif (2048x1024)
1.tif (4096x2048)
2.tif (8192x4096)
I would like to create one tif that is 8192x4096 but have 2 overviews
that are the 0.tif and 1.tif. Is there a GDAL command that I can give
multiple tiffs to create one tiff with
I recently asked about 32 bit GDAL libs with Java bindings for windows. I
really need both 32 and 64 bit binaries.
Thanks,

Anyone know where I can get windows 32 bit GDAL libs pre-compiled with Java
bindings?
Thanks,

I am using java bindings to read in some metadata from image files. I have
a check for images that are in EPSG:4326 (if not I warp them). However I
have an image which I know is EPSG:4326 that has the following:
"GEOGCS["WGS 84",DATUM["WGS_1984",SPHEROID["WGS
84",6378137,298.257223563,AUTHORITY["
Is the java bindings jar and hopefully javadoc jar in a mvn repo somewhere?
Thanks

When get a Dataset Object back from the gdal.AutoCreateWarpedVRT(dataset)
call do I need to call delete on the warped dataset and the original
dataset, or just the original when I am done using the warped dataset?
Sorry I did not understand the javadocs.
Ex
Dataset origDataset= gdal.Open("imagefi
When I run gdalinfo or gdalwarp on a tiff that is a one band image
with elevation data I get the following warning:
EPSG PCS/GCS code 5171 not found in EPSG support files.
I have GDAL_DATA set to /usr/local/share/gdal which I verified has the
data. However looking at the supporting data files in
If I do not provide a source spatial reference to gdalwarp will the
information in the geotiff be used instead? ie. gdalwarp -t_srs
'EPSG:4326' input.tif output.tif?
I do not have a real example because I do not have the file I am working
with on this computer. But an example gdalinfo would be:
ually warp the image right? Only creating virtual
warped points when you ask for them?
Thanks again for all the help, I really appreciate it.

I am not sure what .vrt file you are talking about.
Thanks again

I ran a quick test and confirmed that gdal.AutoCreateWarpedVRT is returning
different results than osr.CoordinateTransformation.
I.E. I opened a file using:
Dataset dataset = gdal.Open("/images/image.tif");
I grabbed the corner point and used
osr.CoordinateTransformation.TransformPoint(), to tran
you. It takes the EPSG Authority code

I have some image files (geotiff's) and I would like to store some of the
metadata about the image files in oracle spatial. Is there any way to get
the SRID for an image file?

I am getting the following warnings/errors when try to open/read NITF files
using gdal 1.8.1. Wondering if anyone has seen these before and can tell
me what they mean.
Warning 1: Block start for block 0 is wrong. Retrying with one extra byte
shift.
Error 1: For , assert sizeX == ds_sizeX failed.
I am getting the following error when trying to open NITF files for read:
Warning 1: Attribute subsection not large enough (124 bytes) to contain 196
attributes.
I am running multi threaded, and processing many different NITF files for
read (I am extracting the metadata). Is this a memory issue?
Is the DataSource.delete() method (from java binding) thread safe?
Thanks

I am able to get VPF (vector product format) info and perform operations
(like convert to shape files) command line using ogrinfo and ogr2ogr. What
I am wondering is if the java bindings for ogr support the same.
i.e. to get a list of layer names
ogrinfo gltp:/vrf/usr4/mppl/v0eur/vmaplv0/eurnasia
I am trying to read VPF files like VMAP0 and having some problems. Far as
I can tell the only way to read VPF using gdal is to compile OGDI.
I compiled on Redhat EL version 5.6 64 bit, gcc 4.2.x
When trying to run ogrinfo (pulled directly from examples). VMAP files are
on
my local box.
ogrinfo
I am using a third party lib (imageio-ext) to leverage gdal in java code.
I have noticed that the imageio-ext folks have wrapped the gdal.Open(..)
call in a synchronized method. I am assuming this is to prevent
imageio-ext users from hanging themselves with regard to thread safety.
