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 how spatial indexes are used and applied, see An overview of spatial indexes in the geodatabase.
- 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.
- 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
