LiDAR Shootout! — New Chart, Final Results

Posted by smathermather on July 21, 2011

Comparison of lidar height calculations

In reviewing the final numbers and charts from Etienne and Pierre, above are the results we see.  The only revision is a moderate increase in speed for the PG Raster query.

Final results in speed for lastools– ~350,000 points per second.  In other words– off-the-charts fast.  And the initial RMSE of ~25 feet was a mistake– it is probably closer to 0.2 feet.

Stay tuned for detailed reviews of these techniques (with code).
