from NMA experience, is used as specification (80 constraints and rules).
The available processes are the ones implemented on CartAGen platform
(Renard et al. 2010): AGENT, CartACom, GAEL, Least Squares, Elastic
Beams and network selection processes. Figure 12 shows the steps of a
rural area generalisation: the rural space is generalised by CartACom and
the road network by the Beams generating a side effect conflict.

ised by the Beams with a side effect on the circled building.
13 shows the registry answer to a rurban space request: three processes
match the pre-condition but CartACom is ranked first as it better matches
the constraints (a 10 constraints caricatural sample is used) a priori (97%
against 59 for Agent and 6% for the Least Squares).

ranked first as it better suits the constraints than Agent or the Least Squares processes.
Figure 14 shows a CollaGen result (without side effect correction) on a
small area with urban, suburban and rural spaces.
