3D Modeling for Archaeology

This week's assignment involved composing interpolated subsurface soil layers (interpreted as the interfaces between topsoil and cultural layers, then cultural and natural layers) from shovel test data. From a point shapefile of shovel tests with the depths to cutural and natural recorded as attributes, depth lines were composed for each test location in ArcScene. The data was also used to create Inverse Distance Weighted surfaces in ArcGIS that were then transferred into ArcScene and extruded to the correct depths.

Also, a flythrough video was generated through the depth lines of the shovel test points.
