Hi there,
First a disclaimer: I come from a 3d graphics background and am
somewhat of a GIS noob. Forgive me if I'm doing something blatently
stupid.
I have a 6000x5000 Erdas .img file containing elevation data as
floating point numbers (GDT_Float32). I can bring up and view this
file in Globa
Hi Bruce-
The KML driver should behave as follows:
If you define a field using a creation option for NameField (the default
is "Name") then it will be written out as the "Name" element. Likewise
with "Description". You're saying that everything works fine using
ogr2ogr but when you try to create
Thanks for your suggestion,
As Jose proposed, I worked out the row and column of my pixel from my (x,y)
location and extracted the value.
I am using the function RasterIO() to do so.
It works fine. I can read a xy file and a ESRI ASCII Raster. As a result I get
an xyz file.

Another idea is a tool called StarSpan.

I would like to replace the projection WKT in a group of MrSID files. I do not
need to modify the compressed image itself, only the metadata. Can I do this
in GDAL?
Thanks,

When I use ogr2ogr to convert a shapefile to KML there are no "Name" or
"Description" fields in the output and all attributes are lined up.
When I try to create a KML file from my code and populate the data both
"Name" and "Description" fields are included in the output.
I have tried not a

I had a similar task where I needed to find the elevation value from a
geotiff at the upstream and downstream points of a river line segment.

Two quick questions:
1. What is libgdalconstjni.so? I've been building and using the JNI
interfaces and just blindly including this file, but I can't determine
what this is and whether I need it. Sorry if this is a stupid question,
I couldn't find the answer in any of the build docs.
2. Is there
Hello,
I have an ESRI ascii raster and would like to get the raster values at defined
x y locations.
At the moment I am capable to load the Raster Dataset and can perform several

on
But is there a function to
