Dear all,

i am trying to projection a shapefile from geodatic projection in WGS84
datum to geodatic projection in sphere datum by using the utility "ogr2ogr

I defined the original projection as:
'+proj=longlat +ellps=WGS84 +datum=WGS84 +no_defs'

and the target projection as :
'+proj=longlat +a=6370997 +b=6370997 +no_defs'

but the result seems no change as compare with the one in WGS84 datum. Did i
miss out something in the above projection definition or ogr2ogr does not
support the datum transformation between WGS84 and sphere?
