Site and heightmap

Over the last week or so, we began to look at site analysis of our given site to build on. Here’s the aerial view of the Chamberlain Golf Course which I obtained from the Auckland GIS Viewer.

We typically tend to use contour lines to contour lines to express the shape of the land as they are remarkably easy to find and are a great visualisation tool, but this time I wanted to try something a little bit different and I created a heightmap in grasshopper. In the image below, the darker regions denote the lowest area of the site, while the white areas are the peaks/crests on the site.

This image is based off of contours we obtained from the site, but to me it works better as a visualisation tool for the shape of the land. The trouble I have with contours is that although they might adequately describe the shape of the land, without height values, it’s difficult to tell whether the site slopes up or down (or both). When we overlay this on top of the site, we get a clearer understanding (in my opinion) of the shape.

The trouble with this method however is that it is far more time consuming than contours as I needed to render this image out in high resolution to be able to print it, whereas contour data, being vectors already, is quite easy to work with. I think this image, paired with the matching contours would provide the best result though.
