| #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

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. |

| #112 | wontfix | Add BigTIFF support to azexhdf | mggr | mggr |
| Description |
Current TIFF formats are limited to 2GB, which is an issue with the Eagle & Hawk - large numbers of bands can easily exceed this limit. Bill says that ERDAS 9.2 supports BigTIFF (and perhaps big geotiffs as a result?). It'd be good to find out the extent of the support and perhaps implement BigTIFF support in azexhdf. This ticket is to track the issue for now. At some point we may want to take action on it. |
