The inputs must contain exactly one object of class SOmap.
SOmerge(..., reproject = TRUE): one or more objects of class SOmap, SOmap_management, or SOmap_legend, or a list of such objects
logical: if TRUE (the default), and any of the input objects are in a different projection to the input SOmap object, an attempt will be made to reproject them. If you run into problems with SOmerge, try setting this to FALSE
A single object of class SOmap.
Note that objects of class SOmap_auto are not yet supported.
