Back to LiDAR peak analysis, and in particular the vertical accuracy of the results... More people over at 14ers.com have gotten involved. A recent post examines in detail how and why two different sets of data might yield different elevation readings for saddles and especially peaks.
"Moral of the story: the determination of summit elevations by airborne LiDAR data has several feet of uncertainty in sharp/rocky areas due to the unknowable effects of the laser footprint on each point's reported Z coordinate. Highly technical aspects of LiDAR data (like the point density and the laser footprint) can make or break a peak's ranked status in some cases..."
