Dogleg Bar, Profile Example 2

Made with Global Mapper. Same conditions apply as previous. Note that I do know how to correct the no-data areas in the LiDAR with ArcGIS...learned at the Users Conference in San Diego last week. Just have not yet had a chance to apply the correction.

Once the missing data are smoothed/averaged, it will be easier to draw a profile. The final one should also be smoothed with a moving average function to eliminate the effect of bushes, etc.

Dogleg Bar, Profile Example 1

This was made with Global Mapper. Couldn't block out the no-data areas, but will use hillshade from prior post. It was made in Arc.

Draft cross section example using LiDAR

From near Bogus point across the kipuka, etc. Shockingly simple to extract in GlobalMaper or ArcGIS. Smoothed in Grapher. Mocked-up in Illustrator. Will work on another that brings in other members of the family.
