I have a shapefile with WGS 84 Geographic Projection. The shapefile contains soil data for the entire world, and comes from the 'Digital Soil Map of the World'. When I opened it in ArcMap, it did not have a projection. I assigned it a WGS 84 projection using ArcCatalog, and it corresponds well with other files.
I need to project the shapefile to Lambert Equal Area Projection. Since I could not find a suitable projection in ArcGIS, I downloaded the prj file from lambert azimutha equal area: SR-ORG Projection -- Spatial Reference. I tried to then use the 'Project (Data Management)' tool to project the shapefile using the downloaded prj file. But the tool asks me for a Geographic Conversion via a drop down menu. What option do I select? I could not find a GCS_WGS_1984 to WGS 1984 option.
The shapefile to be converted has the following info:
|Geographic Coordinate System:||GCS_WGS_1984|
The downloaded prj file has the following info:
Linear Unit: Meter (1.0)
Geographic Coordinate System: Unknown
Angular Unit: Degree (0.0174532925199433)
Prime Meridian: Greenwich (0.0)
Semimajor Axis: 6371007.181
Semiminor Axis: 6371007.181
Inverse Flattening: 0.0
Any help will be very useful! Thanks!
