Hello,
I am new to GDAL and raster programming in general and hoping that I can
get some guidance. I have GeoTIFF which are projected in WGS84 and a
single band.I am trying to start simply with the concept of getting out
the data values from the GeoTIFF from one file so that I compare them to
Hello,
I am running gdal on windows 7 64-bit which I installed via OSGeo4W.
When I run gdalinfo on a raster GeoTiff file I get the following runtime
error: RS6034 An application has made an attempt to load the C runtime
library incorrectly. Any ideas one why this might be occuring, or how I
Please disregard my question on this topic. I was able to resolve this
issue on my own. For the record what I did was open the OSGeo4W
installer and re-install all of the libraries which seems to have
cleaned on some dll conflict I am guessing.
Thanks and I am digging this forum.

Hello,
I was wondering if anyone knows of an editor that color codes mapfile
syntax? I use notepad++ currently for python, but it would be great to
have sytax coloring for .map files.
Thanks,

Hello GDAL guru's,
I am working on a python script where I read in two rasters of similar
extent and resolution.Then I re-assign any values that are greater that
zero to a 1.Next, I compare to the rasters and attempt to create a third
resulting raster which has 1's everywhere that the two inpu

Hello,
I am creating a raster file (.img) in python/gdal
using.GetRasterBand(1).WriteArray it is seems to be working well.Where I
could use some help is in knowing how to color-code/class the resulting
raster.For instance my raster is only ones and zeros.I would like to
make the ones white an

SetRasterColorTable().
You can find some sample python code in GDAL's test suite[1][2].

Hello,
I was hoping someone in the GDAL community could help me out, as I am
stuck on a particular issue of dealing with a source dataset (geotiff)
that has no projection information.Here are the gdalinfo results on the
coordinate system:
Coordinate System is:
/LOCAL_CS[" Geocoding informat
in worrying about datum so do
something like:
gdal_translate -a_srs WGS84 in.tif out.tif
After that you should be able to use gdalwarp to
reproject normally as long as you know the coordinate
system you want to go to.
Best regards,
Frank

Derek,
Please provide the gdalinfo output of the img file.
Also, try this:
Create a vrt file instead of a HFA using the same gdal_translate command.
See
ee if gdalwarp works with the vrt file.

Hello,
Is there a way to do something along the lines of zonal statistics with
gdal.Basically, I have a county shape file and a classified raster
dataset.I would like to count the number of raster pixels/county
(FIPS).Is this possible with GDAL/OGR?If so can someone point me in the
right dire
