Re: Contouring Station Data

Hi Carl,
I notice that you are using the AreaFill contour fill mode. You might get slightly better coverage of the edges if you use RasterFill instead. The areafill algorithm is more likely to leave out areas that are adjacent to fill values. You can use cell fill or raster fill with smoothing off to see the exact locations of the data you do have. Otherwise, I don't know of any solutions other than what you are proposing.
