This estimate type requires the most computation of the three because the bounding box of every geometry is used in calculating the average extent. This procedure determines the extent of all geometries in a layer. Keywords and Parameters layername Specifies the name of the dataset layer. The layername is used to construct the name of the geometry and spatial index tables. Data type is number.
Data type is number.
Data type is number. Data type is number. This procedure returns the coordinates of the minimum-bounding rectangle for all geometric data in a layer. All Rights Reserved.
