I have a vector based csv file that I want to convert into a grid using gdal_grid, but I want to force null data values strictly around the area where there is data. I can get gdal_grid to work but it is always just smoothing the whole grid rather than giving me null data outside of the shape. Can someone tell me what settings to use to make sure that I get null data inside the grid where there is no data within the original csv.
Many thanks
