I created top surface of a coal seam by DTM-Create Surfce and also by GRID Create (IDW2)
as seen below,
and a section view;
it is said that, gridding is the better method for creating surfaces of features such as coal seams, weathering surfaces etc.Also,surface can be extented till boundary, which is good. However; IDW method creates dips and humps at every drillhole. These dips and humps looks unrealistic. In section view, there is a big elevetion diffrence, between two surfaces.According to which model, underground design will be done is a another issue.
any ideas to eliminate these humps and dips?
