Thread: High Accuracy Contours?

LINZ have high accuracy LIDAR surface over much of the country. For the computer geeks out there there is the ability to create accurate contour maps for sussing out new hunting areas, especially in steep terrain. I have had a crash through using some CAD software and have been able to create maps to print along with routes for upload onto GPS apps. My way was too slow to offer up doing it for others. LINZ have more detail on a way of doing it:

Photo attached showing an example of 1m contours generated from LIDAR vs same area zoomed in on Topo50. I was looking to find flatter areas in the bush and routes that avoided steep terrain on a short time budget. I slapped some letters and numbers on there to help with coms etc.

Is it something anyone has mucked around with?
