Blank paper to basemap in 20 minutes

One of the really cool things about lidar data is that you can create a decent basemap really quickly. It took me about 20 minutes to find and download the data, create the contours and generate the "lutning" image that results in the map below.



The "lutning" image does a great job of identifying buildings, trees and walls. But, it doesn't show roads and parking lots. So, another few minutes and you can get the roads, parking lots and sidewalks. The image below is an intensity image.

    I'm using a beta version of OL Laser. Info is at:

    I've also used QuickGrid as a tool for creating contours from "bare earth" lidar data.
