[gdal-dev] ArcGIS 9.3 does not recognize .prj file made with GDAL tools

[Dylan Beaudette]

Hi,

Any idea on why Arc GIS can understand [1] version of a file, and not another 
made by GDAL [2]. This projection file used to work with ArcGIS, and now 
seems not to with version 9.3. Could I be generating the file incorrectly?

Here is the code (python) I used to generate the file [2] with GDAL.


#!/usr/bin/env python
# generate a PRJ file

import osgeo.osr as osr

# Set up spatial reference systems
proj_object = osr.SpatialReference()
proj_object.ImportFromProj4('+proj=aea +x_0=0.0 +y_0=0 +lon_0=-96 +lat_0=40.0 
+lat_1=20 +lat_2=60.0 ellps=GRS80 +datum=NAD83 +units=m +no_defs')

print proj_object.ExportToWkt()


Attachments:
1. ca_geo_new-arcmap.prj 
2. ca_geo_new.prj


Thanks in advance for any ideas.

Dylan
