Dynamic Holland Shading
Thanks to the joys of Open Data and web-apps, Geodan created what Sander Oude-Elberink and myself had a last year as a project for some Minor students:
Dynamic Holland Shading: An interactive viewer to see hillshading in the Netherlands. Based on the newly released 0.5m open data height model for the entire Netherlands.
Use the sliders to see the shade change during the year and during the day.
