Description

Returns min, max, and mean point spacing estimates based on the LAS files whose extents intersect the passed envelope. If only one file is within the extent then min, max, and mean will be the same. If multiple files are intersected the min is set to the file with the smallest spacing, max to the one with the largest, and mean is based on estimating the total points within the envelope.

Point spacing estimates at this level (i.e., the dataset) are based on estimates made per LAS file. They'll be more reliable if statistics for the LAS dataset have been calculated (see ILasDatasetEdit.CalculateStatistics and ILasFile.HasStatistics).
