Hi Greg,
It's always a good idea to communicate via the list, there are more
eyes and skills there. The conversations are also publicly archived,
making it easier for others having similar problems to search for
help.
In this case, the mistake is mine, I see that this list behaves
differently to
Oh - I see. I can open them now and wander through their layers and vector
points. Thank you.
I don't suppose there is a utility/convience function to 'rasterize' the
information within a 2D vector file (e.g. vector map) by any chance (i.e.
rather than drawing them using OpenGL or
There is the GDAL rasterize method, however that is designed to translate vector
polygons into raster representations. Converting points to raster is a very
simple task and does not really need a method; converting lines is slightly less
trivial, however these are issues with regard to how to
Hi All,
I'm trying to write a Ruby app to read the new and fantastic NASA
ASTER Elevation DEM. This is of course in GeoTiff format.
I'm wondering if anyone has examples in any language of using GDAL to
read a particular location's data from a geotiff file? I can do the
calculations to figure out

Thanks Frank,
the command cannot determine it from the .shp file
Why? Is it because the EPSG code of this .shp is unknown to GDAL or GDAL
can't get any SRS from a .shp?
Should I add the EPSG code somewhere in a configuration file?
Best regards,
Steve

There is now an additional wrinkle to the project. We need to now
extract the 4 closest values for a given lat-lon point
to complete a bilinear interpolation for added accuracy.
Would the correct method be:
(1) Use the suggestion that Frank made below about a hybrid approach to
my original

Hi,
I 'm using the GDALAutoCreateWarpedVRT() function to warp a MEM
GDALDataset. When I use the GDALClose() function to close the source
(MEM) dataset nothing happens. However, when I close the warped (VRT)
dataset using GDALClose() I get the following error:

Hi Frank,
Thanks for the help. It seems like you were correct. When I dereference
the MEM dataset the post-decrement reference count is not 0. My question
is: do I not close the MEM dataset since its reference count is not 0?
Best Regards,
Adeel Raza.

Adeel,
You should not be closing the MEM
Hi Frank,
OK - my next question then is: If I close the VRT dataset if it
references the MEM dataset using GDALClose(), would that operation also
close the MEM dataset or would I need to close the MEM dataset after I
close the VRT dataset?
Best Regards,
Adeel.

I have some R code that reads ArcInfo binary grids using the rgdal package.
This code has worked for a long time. Now, with the latest versions of
everything it is failing with the message:

Hello,
I'm looking for the gdalplugin (ogr_PG.dll) for OGR for the PostGres/PostGIS

upgraded to 1.6 and can't seem to find one in the usual places.
I had looked here
