hi all i am using following code for raster to vector conversion but when i use it for 16 bit images it crashing everytime in GDALPolygonize function except i use spatial subset of the 16 bit image, so please suggest me....
here is bunch of code.......
GDALAllRegister();
OGRRegisterAll();
String pszFilename = "C:\Images\s3dImages\geo_liss.tif";
poDataset = (GDALDataset *) GDALOpen( pszFilename, GA_ReadOnly );
GDALRasterBand *poBandR,*poBandMask ;
poBandR = poDataset->GetRasterBand(1);
poBandR->CreateMaskBand(GMF_PER_DATASET);
poBandMask = poBandR->GetMaskBand() ;
poBandMask->Fill(10,0);
const char *pszDriverName = "ESRI Shapefile";
OGRSFDriver *poDriver;
poDriver = OGRSFDriverRegistrar::GetRegistrar()->GetDriverByName(pszDriverName);
OGRDataSource* ds = poDriver->CreateDataSource("Shape", NULL );
OGRLayer* poLayer = ds->CreateLayer("myfile",NULL,wkbMultiPolygon,NULL);
CPLErr er = GDALPolygonize(poBandR , poBandMask , poLayer ,1,NULL,NULL,NULL);
poLayer->SyncToDisk();
OGRDataSource::DestroyDataSource(ds);
regards chirag p.
