Hi Etienne,
maybe you could also use the ESRI WKTs from: http://spatialreference.org/
e.g.: http://spatialreference.org/ref/epsg/4326/esriwkt/

According to the about page, GDAL and proj.4 are used to generate the
database, so it would be of limited use in this case (as the ESRI .prj
files are generated by GDAL).
However, it seems that there are some User-defined (called sr-org)
definitions that might not be related to GDAL?
Hello folks,
I'm a beginner with Gdal and I have a question:
Say,
I have a rectangular tile defined in WGS84 coordinates using longitude
and latitude. I want to receive this file from google for the respective
rect. However, as far as I know, google uses mercator coordinates in
its maps so
Hi all,
I have been trying to override the MODIS WKT definition (derived from
the source HDF4 files using gdal_translate), which apparently is not
sufficient for correct transformations.
The correct srs is '+proj=sinu +R=6371007.181 +nadgrids=@null
+wktext', whereas the one stored in GTiff files
Roger,
Use gdalwarp instead. Set the -t_srs option to EPSG:4326
Extents can be set using -te
Since the projection is changing, specifying the size in percentage of the
original is not possible. You can use -tr or -ts for this.
Also, note the order of the arguments for filenames.

Roger,
It appears that you are attempting to use the GDAL TMS driver to
convert Google Maps Data into a Geotiff, this would be a violation of
the Google Maps Terms and Conditions:

Martin, thanks for this reference!
It seems that the dattrans.htm file contains datum transformations used
by ESRI, with a number of methods.
Would it make any sense to use that information (using a new derived
.csv file) to add TOWGS84 parameters to ESRI WKT definitions, instead
of
I'm not sure I understand. one of these standard ones refers to the
WKT definitions by ESRI? In that case, we could compare the given WKT
(in .prj file), and lookup the associated ESRI code, matching it to
EPSG code.
Correct.
Are you suggesting that we could use the GDAL definition (as

Does anyone know if this made it into 1.8.1? The bug is closed but my

According to the comments in the ticket, this was pushed in the developement
version (1.9.0dev), but not backported
Thanks that's what I just discovered. I applied the patches to 1.8.1 and now
have successfully built ruby bindings for 1.8.1

Would it be possible to do an ogr driver to get the vector features (I guess

indivual vector feature into gdal metadata?
I'm not too familiar with GeoPDF, I just have seen how Adobe allows for

Jared,
I looked into the Poppler library a while ago and decided it was
possible to use it in a way that would allow extracting features
at the vector level from GeoPDF. However, it also looked to be
quite a complex task and it would be capturing vector drawing
primitives which might not be 1:1
I believe I also have access to corresponding files of my GeoPDF samples in
ESRI Personal GeoDatabase .mdb format.
So maybe I am better off just trying to use GDAL's ESRI database driver.
thanks

I wonder if it would be possible to leverage pstoedit
(http://www.pstoedit.net/)? I've used it with Ghostview to extract PDF
vectors to DXF (with no georeferencing of course) with varying success.
