Description

Index is used to indicate which feature class to search and retrieve records from. The index must reference and embedded multipoint feature class.

pAOI is an envelope representing the area of interest. This can be NULL, in which case the full extent of the terrain is used.

resolution is the z-tolerance or windowsize of the pyramid level to query records from. Ideally, the value provided should exactly match an existing pyramid level. If not, the next highest resolution level to the value specified will be used.

pSubFields is an array of field names for desired attributes. Use ITerrain2.GetEmbeddedDataSourceShapeFieldName for the shape field if you're interested in retrieving the geometry.

ppCursor is the output feature cursor.

ppFieldIndices is a LongArray containing the cursor field index values for the requested attributes, listed in the same order as provided in pSubFields.
