Description

Populates the input raster dataset with values that reflect statistical information about measurements from LAS files referenced by a las dataset.

pTrackCancel is a reference to a Cancel Tracker object that can be used to monitor progress and/or cancel the process. This can be set to a NULL pointer ('Nothing' in VB) if desired.

pFilter is a reference to an ILasPointFilter. If set, only points that match the criteria set on the filter are considered while computing statistics. The exception is when the statistics Type property is set to esriLasPointStatsPulseCount. See notes below.

pDataset is the raster dataset to which the point statistics information will be written to. The raster must already exist.

Type is the statistic type computed about the points in each cell of the raster dataset. 

Attribute is the point attribute using which the statistics are computed on a cell by cell basis.

Notes:

For the pulse count stats type, only the filter's AOI is honored, and only points of last-return are counted. The reason is that pulse counts are not well defined when classification codes and flags are used to filter points. A pulse may have multiple returns and each of which may have different a classification code.
