I'm trying to overlay data in WGS 1984 onto an .hdf file projected in NSIDC EASE Grid (EOS (AMSR-E) soil moisture data), however I cannot get my other shape files to correctly transform onto this projection.
I defined the .hdf projection as follows: ArcToolbox > Data Management Tools > Projection and Transformations > Raster > Define Projection > Polar > NSIDC EASE Grid Global.prj
I check the layer properties and set the coordinate system: NSIDC_EASE_Grid_Global Projection: Cylindrical_Equal_Area False_Easting: 0.000000 False_Northing: 0.000000 Central_Meridian: 0.000000 Standard_Parallel_1: 30.000000 Linear Unit: Meter
When importing another layer (in GCS_WGS_1984) I'm automatically prompted to transform it. I convert from GCS_WGS_1984 into GCS_Sphere_International_1924_Authalic. This new layer doesn't overlap at all, however (and dramatically so). Is there some step I've missed? A different approach to take?
