The recommended tiling level in this case will be such that at most 10,000 tiles will be required to completely cover the extent of San Francisco block groups. 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.
