Howdies Tim,<br>
Will take a look at that.<br>
I'm down to about 30 "bad" images which I have just left out of my
tiling run (takes 10 hours... :-( )<br>
<br>
Cheers for now,<br>

<div bgcolor="#FFFFFF" text="#000000" class=""> Hi Guys,<br
class="">
I've been struggling to get some 3200 orthos mosaicked
and tiled.<br class="">
They are very old and have really bad projection
definitions, pixel sizes and metadata funnies.<br
class="">
I'm down to the last 261, and have hit a brick wall,
likely due to my not that great "projection definitions"
knowledge.<br class="">
<br class="">
I get the following error from gdalwarp:<br class="">
<br class="">
<blockquote class="">ERROR 6: Unable to load PROJ.4
library (libproj.so), creation of<br class="">
OGRCoordinateTransformation failed.<br class="">
</blockquote>
I have tried various different gdalwarp parameters -
even leaving gdalwarp to sense in input projection and
me only specifying the output projection.<br class="">
If I leave out both s_srs and t_srs then gdalwarp does
work but obliviously does not reproject to Lo19. <br
class="">
I have even tried feeding the output of this redundant
gdalwarp into a gdalwarp with t_srs, but no success.<br
class="">
<br class="">
Specifying only t_srs (as above) on many other orthos on
Lo17 & Lo21 does work so it is likely that the way
this projection is embedded in this ortho is the
problem.<br class="">
I have tried stripping it out with gdal_edit.py but
haven't gotten that right yet.<br class="">
<br class="">
Anyone with pointers or ideas on this?<br class="">

<div>Have you tried using the corner coordinates and centre to
georeference the image. I assume the corner & centre
coordinates reported are correct and in LoXX ? There is an
example of how to do this in the first reply of this stack
exchange post:</div>
