SAGA.grid_tools.3: Mosaicking

The tool allows one to merge multiple grids into one single grid. This involves resampling if the input grids have different cell sizes or are not aligned to each other. Besides different resampling methods, the tool provides several options on how to handle overlapping areas. It is also possible to apply a histogram matching. <br/><br/>In order to be able to also merge a large amount of grids, which, for example, would exceed the maximum command line length, the tools has the option to provide a file list as input (instead of using the input grid list). This is a text file with the full path to an input grid on each line. Please note the limitiations: (i) the target grid system is set automatically in this case (the extent is calculated from all inputs and the cell size is set to the smallest one detected) and (ii) the input grids must still fit into memory, i.e. are all loaded at once.<br/><br/>
