![]() The raster to be used as the snap raster. ![]() Snap Raster-Sets a raster that is used to define the cell alignment of an output raster. The Snap Raster environment is independent of the Extent environment.A small raster located outside of your analysis area can be used for snapping. The extent of the snap raster does not need to overlap with the output extent.Only its origin and cell size are used to adjust the output extent. The size (the number of rows or columns) of a snap raster is not important.Since the extent can be snapped to a larger extent, the output raster may contain an additional row and column of NoData cells.In that case, only the left and bottom boundaries will align with the snap raster cells, and the upper right corner of the output extent may not coincide with a cell corner of the snap raster. However, it is possible to have the snap raster cell size differ from the output raster cell size. It is recommended that you use the same cell size for the snap and output rasters.You do not need to specify an extent explicitly in the environment to use a snap raster. A snap raster can be used with the default output extent.The extent is not snapped when the output is a feature class, table, or file. In general, the snap raster is applied to tools that output a raster.Output dataType (by default it is the same as the input datatype). 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. One of 'near', 'in', or 'out', for use with alignExtent datatype Character. To maintain cell positions, you can use the option Snap Raster in the. 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. I need this to perform a ecological niche model using a package in R.Specifying a snap raster does not change the values in the output extent control immediately however, the extent is adjusted during execution. ![]() Learn more about how Snap Raster works Usage notes Tools that honor the Snap Raster environment will adjust the extent of output rasters so that they match the cell alignment of the specified snap raster.Ī snap raster is typically used when inputs to tools:
