A related question:
given an unnamed datum with defined spheroid, PRIMEM and UNIT values,
is there a way to find a corresponding named datum or EPSG code?
I'd be interested in an existing method, or perhaps externalng code or
table in which I could search for common candidate DATUM definitions,
a
Thanks Frank,
I think I found a bug in OGRSpatialReference::IsSameGeogCS(), which is
called by IsSame(). The code looks for identical "DATUM" values, but
doesn't check for DATUM="unknown".
In my test, even thought the spheroid values are identical the test fails.
Filed a bug report and one-liner
Etienne,
You should in theory just use OGRSpatialReference::IsSame() method to
see if two coordinate systems are essentially equivelent, but it is not
really all that perfect.
Best regards,

Hi all,
I would appreciate any hints as to how I can compare 2
WKT/OGRSpatialReference objects.
My goal is to make sure that a more detailed WKT (with authority codes
and explicit datum) corresponds (numerically) to a simpler one, such
as in the following examples.
I understand that the oSRSGDAL
Jay,
The gdal_merge script needs the images to match in the coordinate system and
the number of bands.
One likely problem is could be different data types. Provide the gdalinfo
outputs of the images.
Before you try that, use the gdalbuildvrt program to create a vrt file and
then gdal_translate t

You might try building a vrt file first and then converting that.
gdalbuildvrt merge.vrt *.tif
-or just merge the original IMGs-
gdalbuildvrt merge.vrt *.img
-then-

Sent with an example attachment, which is awaiting approval. Here is the
mail without attachement.
I have 8 large Gtiffs which I am trying to mosaic. Tiffs were created from
.IMG files downloaded from PDS. I converted to tif using:
gdal_translate -of GTiff -scale -co "TILED=YES" -co "
Thanks for the help guys. I've managed to figure it out in code.
A quick note though, wouldn't X correspond to lon (increase/decrease
horizontally) and Y correspond to lat (increase/decrease vertically)?
And shouldn't the far pixel count be the extent minus one since it's zero
indexed?
Here is a
