Helllo,
I am currently working on a project that regards a photovoltaic park implementation.I need to create, from a current DEM, a new surface which resembles the existing ground but in a way that the implementation of the panels will be possible. This means that with the least possible earthwork, the new surface will have form able for this application. By filling sinks or cutting ground we must form sections of unique slope across each polygon.
I tried to work with the ''topo to raster' or the ''spline'' interpolation functions in ArcMap, but the new surface that I get does not have a unique slope or at least a constant slope for some distance of each polygon, and so it will be quite impossible to be constructed in the field. I think the best thing would be the new surface to present a form of a multipolygon that in each section, each polygon will have its one (according to the specific ground section) unique slope and these sections will demonstrate the existing ground in a more costruction friendly way.
