Description

Is anyone aware of the use of gdalwarp on gtiff files; projecting from Michigan Oblique Mercator (epsg 3078) to WGS84 (epsg 4326)? We end up NE of Alaska, where as the original tifs overlay just fine in MI when using ArcMap 9.3.1

These are tifs of high res orthos flown in 2006 over Lake County MI; the MI projection info appears correct in the tags.

We have quite a bit of high res ortho datasets; at times we have to modify tfws/tags, however this one has us stumped(!)

Here is the gdalinfo of the original GTIFF; it also interprets the xys to lat/longs in Alaska:

TIF: gdalinfo 085_r3c25.tif Driver: GTiff/GeoTIFF Size is 1619, 1708 Coordinate System is: PROJCS[" Projection Name = Oblique Mercator (Hotine) Units = meters GeoTIFF Units = meters",

Any advice or suggestions would be greatly appreciated!

Might be another instance of a more general problem when dealing with Hotine Oblique Mercator, as in #2745 or #3038
