module is to create multiple output maps containing the results of
hierarchical segmentation. So why would one need one single output map
name ?
Actually I wrote this module to have a single segmented output map! :-)
The idea of the module was to parallelize the i.segment module into cores
and nodes in a cluster on single tiles, once the segmentation per tile is
done then patch the tiles in a unique map and apply i.segment using the
segmented map as seed to obtain as output a large segmented map.
I put also the option outputs_prefix, that probably should be change in
"basename" to define the name of the "temporary" segmented tiles.
