Output Spatial Grid 1, 2, 3 (Environment setting)

Tools that honor the Output Spatial Grid 1, 2, and 3 environments will create feature classes that have the specified spatial index grids if those feature classes support spatial index grids.

To learn more about spatial indexes are used and applied, see A quick tour of setting a spatial index and An overview of spatial indexes in the geodatabase.

Usage notes

• One to three grids will be created for output feature classes, depending on the type of geodatabase and geometry storage type.
• The first, or lowest, grid level has the smallest cell size.
• If you only want one grid, set all others to zero (0).
• If more than one grid is used, each successive grid must be set at least three times larger than the previous level.
• Note:

  If you are unfamiliar with creating spatial index grids, use the default value provided, as creating a poorly defined grid will increase the time needed to complete a spatial search.

Dialog syntax

• Output Spatial Grid 1—A numeric value for the grid cell size 1
• Output Spatial Grid 2—A numeric value for the grid cell size 2
• Output Spatial Grid 3—A numeric value for the grid cell size 3

Scripting syntax

arcpy.env.spatialGrid1 = cellsize_value

arcpy.env.spatialGrid2 = cellsize_value

arcpy.env.spatialGrid3 = cellsize_value

Parameter	Explanation
cellsize_value	A numeric value for the grid cell size

spatialGrid1, spatialGrid2, and spatialGrid3 syntax

import arcpy
