GDAL: Writing Albers Projection to HFA format

[knelson@…]

When creating images in ERDAS Imagine HFA format using the Albers Conical Equal
Area projection, ERDAS does not recognize the projection as valid.  The problem
is that ERDAS expects Albers Conic"AL" Equal Area and GDAL writes the projection
name as Albers Conic Equal Area (no "AL").  The projection is read correctly
using the same HFA files in ENVI or ArcGIS, so it is an ERDAS issue.

RESOLUTION:

I modified the source for the HFA driver to add the "al" to the projection name.
File: GDAL_ROOT\frmts\hfa\hfadataset.cpp
Line: 1491
Original:         sPro.proName = "Albers Conic Equal Area";
Changed to:         sPro.proName = "Albers Conical Equal Area";


This appears to correct the issue.  I tested a small number of images after
making this fix and rebuilding GDAL and found the projection information to be
read correctly in ERDAS, ENVI and ArcGIS.

Versions: 
  GDAL 1.3.1
  ERDAS Imagine 8.7
  ENVI 4.0
  ArcGIS 9.1

I have applied your patch in CVS, thanks!

It's funny that they key on the string instead of the 
numeric code.
