ERS file driver not handling case of 1 m pixel resolutions correctly

Reported by: sran Owned by: warmerdam
Priority: normal Milestone: 1.9.0
Component: GDAL_Raster Version: 1.8.0
Severity: normal Keywords:

Description

For the case of pixel resolutions of 1 unit, ER Mapper 7.2 omits to write the RasterInfo.CellInfo group in the ERS file. This results in the failure of gdal to create a geotransform for the dataset. It looks like poHeader->Find( "RasterInfo.CellInfo.Xdimension", NULL ) in ersdataset.cpp should not be part of the criterion to determine the presence of a geotransform.

Oops, ignore previous comment. Copy&paste error. Correct commit is :
