Learning heightfields Pt 1: Heightfields?

This video is part of a series covering the basics of houdini's heightfield system.
For this series you'll need a basic understanding of houdini.
These videos were made as additional material for first year artists at IGAD nhtv.

This is the first time I'm making these type of videos so feedback is very welcome!
