KannanKrishnan — Mon, 17 Nov 2014 15:26:13 GMT

I was able to use raster files and the field information using C# code. please guide me if you guys have any ideas...

public IRaster OpenRaster(string directoryName, string fileName)

{

IWorkspaceFactory workspaceFactory = new RasterWorkspaceFactoryClass();

IRasterWorkspace rasterWorkspace = default(IRasterWorkspace);

IRasterDataset rasterDataset = null;

try

{

rasterWorkspace = workspaceFactory.OpenFromFile(directoryName, 0) as IRasterWorkspace;

rasterDataset = rasterWorkspace.OpenRasterDataset(fileName);

}

catch (Exception ex)

{

}

IRasterLayer pRasterLayer = new RasterLayer();

pRasterLayer.CreateFromDataset(rasterDataset);

IRaster pRaster = null;

pRaster = pRasterLayer.Raster;

return pRaster;

}

using the return values... i want able to get the field values of passing point values( lat,long).

Regards,

Kans
