#43 wontfix Point cloud conversion in azgcorr mggr mggr
Description

azgcorr's point cloud conversion function appears to have a problem with correctly detecting the UTM zone from a ULM LIDAR point cloud. Specifically, with a file like:

  472077.149175 30593792.77 4095708.38  131.27    87 30593792.77 4095708.39  131.31    87

and running azgcorr -ELpt f1 x -d7 0 -87 -98 -121 0 0 0 0 -mUTMZ 30 -e Str_287.first1000, you get:

The first time the central meridian appears in the output, it is -0.0288 (should be -3). On subsequent runs, this number changes at random.

Specifying the meridian manually (e.g. azgcorr -ELpt f1 W003 -d7 0 -87 -98 -121 0 0 0 0 -mUTMZ 30 -e Str_287.first1000-nozone) appears to work. Rather oddly, it doesn't appear to matter if the UTM zone is stripped from the coordinates or not - the output is identical.

Contacting Bill to see if this is a bug or a misunderstanding on our part.

#44 fixed azgcorr 7-point Bursa-Wolff datum transformations not working correctly mggr mggr
Description

From Chris Hecker (support ticket #42):

Since all our datasets are in ED50, I was trying in a next step, to get
that working. However, azgcorr seems to have troubles with the -d7
option. I use the following statement (without DEM at the moment):

azgcorr -1 h153131b.hdf -3 h153131b_out_noDEM_ED50.hdf -BIout \
-d7 0 -87 -98 -121 0 0 0 0 -mUTMZ 30 \
-in -p 2 2 -bl 100 -1 \
-v > h153131b_out_noDEM_ED50.txt

This should give me UTM Zone 30 for ED50 mean. However, the -v output to
the txt file shows that it uses Datum Shift type "Dutch" which is made
for RD reference system (not UTM at all) with Bessel ellipsoid etc, so
something different.

Confirmed this does the same for me, example output:

Note: NO DEM is being used which means that if significant topographic
      variation is present the geocorrected image will be unsuitable for
      accurate georeferencing against map or vector data or for mosaicing
      with adjacent lines, see User Guide for more details
