Extent
サマリ
An extent is a rectangle specified by providing the coordinate of the lower left corner and the coordinate of the upper right corner in map units.
説明
When used as input to the Spatial Analyst tools, Create Constant Raster, Create Normal Raster, Create Random Raster, Extract By Rectangle and Topo To Raster only the XMin, YMin, XMax and YMax values are used by these tools.
