Polygon connecting network
Polygon connecting network is defined as a figure connect-
ing the two adjacent shapes by at least 3 common points.
So this network at
least needs 4 receivers. It is better than side
connecting network in accu
racy but not working time. So it is
only suggested for high precision control surveying.

Because every type of network has its own disadvantage, so we can use Mixed connecting
network which can combine the advantages of these types to achieve higher efficiency
working but lower investment both in time and money.
Mixed connecting network is also the common type in doing the surveying job.
