Occassional thoughts about orienteering

More tests with laser scan/lidar data for mappingI've been experimenting with laser scan data and the latest version of OL-Laser. I've been learning more and more about how to use the data and what sort of information I can get.
Here's an image that combines the laser scan contours and cliffs generated by the OL-Laser software. You can tweak the contours and cliff settings, but the image is just to give you an idea of the basic information that is easy to pull out of the data with OL Laser.
The next image shows the results of some quick field checking. You can see some adjustments to the contours (and, in fact, the contours in the field checked image were derived from the same data but created with QuickGrid rather than OL Laser).
The snapshot shows the lone cliff that is a bit east of the pair of boulders.
The below snapshot shows some of the area that OL Laser picked out as a cliff but that I've mapped with the boulder field symbol
