[mapguide-users] can anyone solved this buffer problem

[padmini godavarthi]

 Hi,
iam using mapguide opensource 2.0 (with .net 2.0 +IIS 5.1)
i want to make a buffer to my data
the buffer function works fine for this sheboygan data but not for my data
i have debugged the application and i got the error at

    MgResourceIdentifier featSourceId = new
MgResourceIdentifier(selLayer.GetFeatureSourceId());
            MgSpatialContextReader ctxs =
featureSrvc.GetSpatialContexts(featSourceId, false);
            String srsDefDs = "";
            if (ctxs != null && ctxs.ReadNext())
      srsDefDs = ctxs.GetCoordinateSystemWkt();

In Sheboygan data  
srsDefDs comes as  GEOGCS["WGS84 Lat/Long's, Degrees, -180 ==>
+180",DATUM["D_WGS_1984",SPHEROID["World_Geodetic_System_of_1984",6378137,298.257222932867]],PRIMEM["Greenwich",0],UNIT["Degree",0.017453292519943295]]

but for my data
  srsDefDs comes as null 

Actually my data is in coordinate system 

GEOGCS["WGS 84",DATUM["WGS_1984",SPHEROID["WGS
84",6378137,298.257223563,AUTHORITY["EPSG","7030"]],TOWGS84[0,0,0,0,0,0,0],AUTHORITY["EPSG","6326"]],PRIMEM["Greenwich",0,AUTHORITY["EPSG","8901"]],UNIT["degree",0.01745329251994328,AUTHORITY["EPSG","9122"]],AUTHORITY["EPSG","4326"]]

can u plz tell me the solution????????????????????????

plzzz

Regards,
Padmini.
