CCS, also, displays locations of all emergence response
units in the surrounding area of the incident. The CCS officer
can choose a particular emergency unit(s) to response or move
to the site. To response an incident according to reporting, CCS
allows control center officer to identify the types and the
number of emergency response units to be display on CCS
map. For example, an accident with one elderly person of
minor injury may need only one ambulance, a few polices, but
neither firefighter nor national guards. However, for a better
coverage during searching, control center officers may search a
few ambulances, and many police officers patrolling in the
surrounding area so that they can choose proper response units.
