Description

The input index is the terrain data source index of the embedded feature class. Valid values range from 0 to ITerrain.DataSourceCount-1.

The pAOI argument is the area of interest envelope that's used to indicate where measurements are to be replaced.

pInFC is a pointer to the input feature class from which measurements will be taken. The feature class shape type must be point or multipoint.

pTrackCancel is a pointer to a CancelTracker object.

Notes

• Replacing data source data will create dirty tiles in the terrain. You will need to (re)build the terrain afterward. See ITerrainEdit.Build.
• If the target embedded feature class has attributes (e.g., LIDAR intensity, class codes) the input feature class is expected to have them also. Matching fields, from source to target, is based on field name. If the input feature class shape type is point then the values of attributes need to fall in a range compatible with the BLOB type they will be written to. If the input feature class shape type is multipoint then the attribute values need to be stored in BLOBs compatible with TerrainBlobReader and TerrainBlobWriter objects and the BLOB data types (see ITerrainBlobReader.GetDataType) need to be the same.
