topic Creating Basin Mask for NetCDF File in Data Management Questions https://community.esri.com/t5/data-management-questions/creating-basin-mask-for-netcdf-file/m-p/551153#M31205 <HTML><HEAD></HEAD><BODY><SPAN>Hello, I have a large rectangular domain (topography) in NetCDF file and I am supposed to create a basin mask for further rainfall processing inside the domain. I have defined the basin borders I will use, but don't know what to do next. I have to assign the value -9999 to every pixel outside my basins , so the model simulator I will use later won't operate on unnecessary land.</SPAN><BR /><BR /><SPAN>The file attached shows the screenshot of my domain and needed basins to give you an idea. As a note: my basin borders are currently imported from CAD file as Polygons.</SPAN><BR /><BR /><SPAN>I will be faithful if someone can offer some step-by-step process that I'm supposed to do.</SPAN><BR /><BR /><SPAN>Thanks in advance,</SPAN><BR /><BR /><SPAN>Al</SPAN></BODY></HTML> Mon, 12 Mar 2012 12:06:43 GMT AlperOnen 2012-03-12T12:06:43Z Creating Basin Mask for NetCDF File https://community.esri.com/t5/data-management-questions/creating-basin-mask-for-netcdf-file/m-p/551153#M31205 <HTML><HEAD></HEAD><BODY><SPAN>Hello, I have a large rectangular domain (topography) in NetCDF file and I am supposed to create a basin mask for further rainfall processing inside the domain.
