Hi,
The original image is georeferenced with ground control points and direct
conversion into GeoTIFF does not change the situation. Use gdalwarp instead. It
might be good to use some extra options like –srcnodata, -dstnodata or
-dstalpha for handling nodata but this command should be good enough for
testing:
gdalwarp -of GTiff -s_srs epsg:4326 –t_srs epsg_4326 -co TILED=YES myFile.ntf
myFileConvertedToGeotif.tif

OK – well if the geoserver mosaic function is not supposed to deal with random
NITF files and re-warping images – how come if I convert them first to geotif
(without warping the imagery) the mosaicing tool accepts them and produces a
(approximate) rectified mosaic?
Again, as I said in the other thread, could you please provide us the gdalinfo
output of this geotiff?
I think that gdal is doing some processing operation on the input NITF.
I’m sure this thing is designed to do what I want, but it just does not accept
NITF files.
I notice that gdalinfo does not populate the geo-corners with the information
from the IGEOLO but instead simply loads the image extent in pixel space,
despite correctly populating the GCPs with lat/longs. gdalinfo is clearly
showing the projection to be WGS84 EPSG:4326,
Could you please provide the gdalinfo output for both the original NITF and the
produced GeoTIFF?
it knows where the corners are in lat long space, so why is this information
not used by GDAL to populate the image corners used by geoserver?
(incidentally, “gdal_translate –of GTiff my.ntf aNew.tif” does not produce a
valid georeferenced geotif.
What do you mean?
I had to go first convert to geo-pdf and then to geotif for some reason)
Not sure about this. Maybe the Geo-PDF driver does some hack.
Please, let us know.

Daniele

I don’t think I have ever seen a NITF output from GDAL which reports anything
on the line ‘Coordinate System is:’ – I was under the impression that the
wealth of information below described the Coordinate System.
I was also under the impression that geoserver could import random NITF images
(these are large NADIR views) and serve them through the WMS (i.e. presumably
using GDAL to orthorectify the imagery en-route). To do this, I thought it
used the four corner georeferencing clearly contained in this NITF file and all
the others I have.
Is this not the case? I can see the images using the ‘layer preview’ tool, so
I presume it can serve them somehow – and they look warped as required. But
they just seem to be in the wrong place on the Earth!
Ha ha, you certainly made a large number of assumptions there :-p
No, GeoServer does does not do any ortorectification on the fly, gdal or not.
As Daniele suggested, you should fix those files using gdalwarp, so that they
are truly rectified.
Or, if you really want GeoServer to follow the path you imagined, you can
either add features to it yourself, the code is there for everybody, or check
commercial support (http://geoserver.org/support/) to have someone do it for you
Cheers
Andrea
