    ByVal pTargetSpatialReference As ISpatialReference _
) As IEnvelope

[C#]
public IEnvelope GetDataExtent (
    ISpatialReference pTargetSpatialReference
);

[C++]
HRESULT GetDataExtent(
  ISpatialReference* pTargetSpatialReference,
  IEnvelope** ppExt
);

[C++]

Parameters
pTargetSpatialReference [in]

  pTargetSpatialReference is a parameter of type ISpatialReference
ppExt [out, retval]

  ppExt is a parameter of type IEnvelope

Description

Returns the data extent of points in the files referenced by the importer. See AddFile and AddFolder.

LAS format LIDAR files contain the data extent in the header. From them, the extent can be extracted quickly. ASCII files, on the other hand, must be scanned to discover the extent. The time this will take is proportional to the amount of data to scan through.
