![]() 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.But I need to set 1-5 as a class, and 2-3 as another class, and 4-4 NA values. In this third module, were going to start off with. Earth Data Science - Earth Lab Dhonatan Pessi 3 years ago Hello, In my case I have a k-means classification in R and the class were classification in values into 1 to 5. Only its origin and cell size are used to adjust the output extent. Video created by University of California, Davis for the course Geospatial and Environmental Analysis. 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.
