Hi

I am trying to create a raster of the shape of a depression wetland. I managed to do it a while back getting the results I wanted (see: [ATTACH=CONFIG]26192[/ATTACH]). However, I cannot seem to remember what tool I used!! I have tried various interpolation techniques (spline. idw, kirgging etc), at various cell sizes and powers, but none of them return the result i want/ need. THe closest I could get was using spline: [ATTACH=CONFIG]26193[/ATTACH]), but it doesn't represent the shape of the feature nearly as well. The input data are points taken during surveying.

If anyone could help that would be great!
