HI !
i try to merge two image with the following command:
gdal_merge -v -o D:\CAD\Schulungen\GDAL\\test.tif -of GTIFF -co
--optfile D:\CAD\Schulungen\GDAL\\filelist.txt
but there only will be one image convert into a ~250 gb file with this
message:
d:\cad\FWTools2.4.6>gdal_merge -v
If we assume that each S57 object corresponds to a real world entity -
in my opinion the best encoding would be a separate line object. I.e.
the main road is a point to point entity (as LineString supports) and
the spur from the east (such as the one from Ljubicevac) is a separate
line. That would

Try with GDAL 1.7.1 instead... this is the I could compile with
(--without-libtool).

Hi!
Found the answer to the problem described in the original email !
The XML file configuration of gdal_translate was wrong. The bounding
box coordinates had to be adapted for a tile base request (TMS). I had
to expand the rigth border to take in account the tile pixel size and
the scale factor

Hi Everyone,
Please indulge me in this slightly off topic question.
As I have spent the last many years of my GIS life programming in a
(linux BASH-like) scripting language, I am somewhat out of date with
Linux development environments.

Hi,
I am searching for a pure Java library to convert GeoJSON objects into
ESRI Shapefiles and vice-versa, preferably open source...
Up to the moment I found only ogr2ogr with Java binding and the ArcGIS
tools to do this task.

I used the following to do the conversion:
ogr2ogr -f GML test.gml test.shp
I got a file test.gml and test.xsd which appear to have the polygons and
geometry in them. When I try to look at it with ogrinfo I get

Dear GDAL,
What is the difference between gdal_translate's "assign nodata" and
gdalwarp's "destination nodata"?
thanks!

I believe -a_nodata in gdal_translate sets the no data value as in
GDALRasterBand::SetNoDataValue(). -dstnodata in gdalwarp initializes the
bands with the supplied value, but doesn't call
GDALRasterBand::SetNoDataValue(). I think.

Ok, I got gdal rebuilt with xercesc support, and I can read it with ogrinfo.
But it says:

I reopened Ticket #3564 to submit a modified TSX driver. Changes made by Adam

First you have to locate the corner pixels corresponding to the lat/longs
you indicated. Go through (http://www.gdal.org/ogr/osr_tutorial.html) to do
that. Use "WGS84" system for lat/longs.
Use GDALRasterIO() (http://www.gdal.org/gdal_tutorial.html) to retrieve the
pixels from the re
Jim,
GML driver doesn't support reporting of the geometry type for the layer.
However, you will get the right geometry when you ask for the geometry
itself. Try "ogrinfo -al test.gml" and check the reported geometries.
