1m DEM
Last time, one of the questions was, which digital elevation model (or DEM) should I use. Initially I worked with the relatively low-resolution DEM derived from the 20m contour lines.
Of course, Auckland Council has had a 1m DEM derived from lidar data for a while. There’s also a digital surface model, which doesn’t follow the ground level, but which models the ‘surface’ visible from above. You’ll see the buildings and tree tops on that one.
