I have a large LAS Dataset, consisting of about 25 tiles. I used the LAS Dataset to raster tool in order to create a raster surface from the Lidar data, the DEM itself prior to creation of the raster surface had Z-values. The photo snip attached, snip_example_1, is how I processed the LAS dataset.
Next from the DEM, contour lines were generated. How I ran the tool is below attached, "Snip_example_2". My main question here is what is the easiest way to verify there are Z-values on these contours? They are to be utilized to create 3D surfaces eventually, but searching through the web and other sources I cannot seem to verify any actual methods to pretty much check the data for accuracy/elevation. Any examples, tips?
