Missing GCS_ prefix after ESRI PE string is written to an IMG and read back

[gaopeng]

The problem is that the GCS_ prefix is lost after the round trip. Here are the before and afrer PE strings. PROJCS names are also different. The specific name, "Sudan_UTM_Zone_35N" is changed to a more generic name, "UTM Zone 35, Northern Hemisphere".

Before: PROJCS["Sudan_UTM_Zone_35N",GEOGCS["GCS_Sudan",DATUM["D_Sudan",SPHEROID["Clarke_1880_IGN",6378249.2,293.46602]],PRIMEM["Greenwich",0],UNIT["Degree",0.017453292519943295]],PROJECTIONTransverse_Mercator,PARAMETER["False_Easting",500000],PARAMETER["False_Northing",0],PARAMETER["Central_Meridian",27],PARAMETER["Scale_Factor",0.9996],PARAMETER["Latitude_Of_Origin",0],UNIT["Meter",1]]
