Comparing Lidar base to the old O' map

Here is a comparison of the old orienteering map and the Lidar map I wrote about yesterday. We fieldchecked the old map a long time ago (1988-89, I think). The basemap we used was from the US Corps of Engineers. My memory is that it had 10 foot contour intervals. The quality was good.





For anyone interested in Lidar, I would encourage you to download a couple of the free software tools that let you look at the data (Quickgrid and Global Mapper are the ones I've used), find some data, and see what you can do. I don't know much about finding data, but there is plenty of free data to download at the Kansas geodatabase catalog (look for bare earth data under "elevation" and use it to make contours in Quickgrid).

Here is everything I've written about Lidar.
