Hi!
I have a problem when projecting a raster file.
The tool I am using is Project Raster. I have a grid file of Landuse in Africa:

COORDINATE REFERENCE
TYPE Projected
PROJECTION lambert
GEOGRAPHIC COORDINATE REFERENCE GCS_Lambert
COORDINATE REFERENCE DETAILS
PROJECTED COORDINATE SYSTEM
X ORIGIN -200
Y ORIGIN -5385200
XY SCALE 22517998136852.477
Z ORIGIN -100000
Z SCALE 10000
M ORIGIN -100000
M SCALE 10000

I want to project it to:
Africa_Albers_Equal_Area_Conic
Projection: Albers
False_Easting: 0.000000
False_Northing: 0.000000
Central_Meridian: 25.000000
Standard_Parallel_1: 20.000000
Standard_Parallel_2: -23.000000
Latitude_Of_Origin: 0.000000
Linear Unit: Meter (1.000000)

Geographic Coordinate System: GCS_WGS_1984
Angular Unit: Degree (0.017453292519943299)
Prime Meridian: Greenwich (0.000000000000000000)
Datum: D_WGS_1984

When I want to project it the whole program shuts down. I Dont know What I am doing wrong. I have tried everything. I also set the environmental settings but that didnt help either. I also should mention that I have service pack 5 installed but still the projection didnt work out.
I would be very please if anyone could help me solve this issue.

Hi!
The original file was a *bsq. file. So I converted the file to an ESRI GRID file using Raster To Other Format- tool. I chose GRID as Raster format. But there arent any prj.adf file in the original file (after a converted the file to a grid format).. Should there exist a file like that? But after I define the grid layer I get a prj.adf file and it looks like this:

Projection    LAMBERT_AZIMUTHAL
Spheroid      SPHERE
Units         METERS
Zunits        NO
Xshift        0.0
Yshift        0.0
Parameters   
6370997.0 /* radius of the sphere of reference
  20  0  0.0 /* longitude of center of projection
   5  0  0.0 /* latitude of center of projection
0.0 /* false easting (meters)
0.0 /* false northing (meters)

The last image I posted was an Africa Albers Equal Area Conic projection. That was when I projected the layer and not when I defined the layer. Sorry I should have mention it.

I opened the properties of the data frame (where the map looks normal and not like in the pic above) and saw that the datum was in D_Sphere_ARC_INFO. And when I open the map in a new data frame and checked the properties for the new data frame it changed to WGS_84 and thats when the map looks strange. Whats the problem here then? Do you think theres something wrong with the transformation from D_Sphere_ARC_INFO to WGS_84 when I project the file?
