Connectivity (Network) Operations:‣Each connectivity function must include the following:‣1. a specification of the ways spatial elements (such as roads) areinterconnected‣2. a set of rules that specify the allowed movement along theseinterconnections‣3. a unit of measurement‣ The widely used connectivity operations are:‣ contiguity measures‣proximity analysis‣ network operations80
Connectivity (Network) Operations:Contiguity measures evaluate the characteristics of spatial units that areconnected A contiguous area consists of a group of spatial units that are connectedForexample seach a land unit to be used as a park might be specified as a contiguous land unit offorest having minimum area of 1000 square km.81
