![]() The upper right corner of the given extent is moved to the nearest output raster cell corner in such a way that the new upper right corner is outside the given extent.įigure (a) shows the extent to be snapped. If the lower left corner of the given extent already coincides with a cell corner of the snap raster, no adjustment will be made. The lower left corner of the given extent is moved to the nearest snap raster cell corner in such a way that the new lower left corner is outside of the given extent. The purpose of the snap raster is to adjust the extent so that the cells in the output raster align with the cells in the snap raster.įor a given snap raster and an extent (extent to be snapped), as shown in figure (a) below, the output extent is determined by adjusting the lower left and upper right corners. This ensures that cells or features along the boundary are included during execution when the output extent is set to the input dataset.Įxtent and Snap Raster environment settings are shown. The output extent after snapping can be the same as the pre-snapped extent, or it can be larger (but never smaller). ![]() ![]() The parameter extent specified as a parameter input to a tool overrides the environment output extent. Note that some tools have a particular behavior with respect to how the extent is handled see the help for the particular tool for more information.Īny non-default setting for the output extent (in other words, Union of Inputs, Current Display Extent, or As Specified Below) overrides the default input dataset extent. For multiple inputs, the extent is the intersection of those inputs. With the default option for the Extent environment setting, for a single input dataset, the extent is the same as that dataset. The extent to be snapped depends on the following: As a result, when the output cell size is the same as the snap raster cell size, the cells in the output raster are aligned with the cells of the snap raster. The lower left corner of the extent is snapped to a cell corner of the snap raster and the upper right corner is adjusted using the output cell size. ![]() The Snap Raster environment is used to snap or align an extent during execution. ![]()
