Topological Relations between Rivers in Updating Increments
Abstract:
Topological relations between rivers (TRR) are sophisticated for rivers are shown as various patterns in Geographical Information Sciences (GIS). In this paper, basic models which were simplified into directed lines (DL) and directed bandings (DB) were used to represent TRR. Based on the nine-intersection model (NIM), topological relations (TR) were represented into 3 types of DL-DL TR, 7 types of DL-DB TR, and 8 types of DB-DB TR. Otherwise, the four-intersection model (FIM) and common region-region topological relations were testified not suitable to represent TRR in updating increments (UI).
