Hi, I am upgrading a 9.2 Arcobjects console application to 10.2 and I am having some problems with changing the spatialReference of rasters. My application looks at a TIFF file (plain TIFF) , plus an associated .TFW & .PRJ file. In the 9.3 version of the application, it made changes to the header tags of the .TIF file, writing the spatial reference directly into the TIFFIn my upgraded 10.2 application, this part no longer works - the TIFF does not get altered & ArcMap still thinks the TIFF has unknown spatial references, and I can't figure out why. Can anyone Help? BillVersion 10.2 code.
string pathName = Directory.GetCurrentDirectory();
ESRI.ArcGIS.RuntimeManager.Bind(ESRI.ArcGIS.ProductCode.Engine);
//// Force ESRI to pick up the new Spatial reference from the .prj file
ISpatialReferenceFactory pSpatialReferenceFactory = new SpatialReferenceEnvironmentClass();
ISpatialReference pSpatialReference = pSpatialReferenceFactory.CreateESRISpatialReferenceFromPRJFile(prjFileName);
// open the directory as a worekspace
Type factoryType = Type.GetTypeFromProgID("esriDataSourcesRaster.RasterWorkspaceFactory");
IWorkspaceFactory workspaceFactory = (IWorkspaceFactory)Activator.CreateInstance(factoryType);
IWorkspace workspace = workspaceFactory.OpenFromFile(pathName, 0);
IRasterWorkspace rasterWorkspace = (IRasterWorkspace)workspace;
// open the raster file
IRasterDataset r = (IRasterDataset)rasterWorkspace.OpenRasterDataset(tifFileName);
r.BasicOpenFromFile(tifFileName); // not sure if this line is needed
IGeoDataset igs = r as IGeoDataset;
IGeoDatasetSchemaEdit2 gds = r as IGeoDatasetSchemaEdit2;
gds.AlterSpatialReference( pSpatialReference) ;
igs.SpatialReference.Changed(); // tell it that we have changed the rasters's spatial reference
Original 9.2 Code (which no longer compiles under 10.2 // Force ESRI to pick up the new Spatial reference
ISpatialReferenceFactory pSpatialReferenceFactory = new SpatialReferenceEnvironmentClass();
ISpatialReference pSpatialReference = pSpatialReferenceFactory.CreateESRISpatialReferenceFromPRJFile(prjFileName);
// Open the Raster & change its SpartialReference
RasterDatasetClass r = new RasterDatasetClass();
r.BasicOpenFromFile(tifFileName);
r.AlterSpatialReference(pSpatialReference);
