Hi Byron: If I understand this correctly, you are concerned with how the contours will be generated at the edge of your raster data.  If I have this correct, I would grid the data that you have based on the attribute you want to contour. Create a vector clip layer for your study area that is

i have a large geologic dataset that i want to grid and contour. There is an irregular zero edge that bounds these data on one side and a straight bounding area edge on the other sides. If i create an irregular polygon that encloses these data, is there a way to grid and contour such that these da
