Are you sure you mean topological data science? I know that there are topological methods for classifying high-dimensional data structures, but this discussion is mostly geographical/topographical. Yes, it does describe a surface, but there's a fundamental assumption that all objects are either on a plane or a sphere.

edit: If you mean GIS (geographical information systems/science), there are plenty of undergraduate courses strewn over github. IMO, the R geospatial ecosystem is more mature than its Python counterpart, but both are very usable.
