A FUZZY TOPOLOGY FOR OPERATOR IN SPATIAL OBJECT QUANTITATIVELY IN FLOOD PREDICTION

Abstract

For the time being in GIS application fuzzy spatial objects have become extremely important. There have been many research developments on the conceptual description of the topological relation between spatial objects. In this paper a formal definition of the computational fuzzy topology is shown which is based on the interior operator and closure operators. In spatial object modeling the interior and exterior boundary are computed based on computational fuzzy topology. An example for determining interior boundary and exterior boundary of the flood affected area of Chennai based on data collected from Integrated Multi-Satellite Retrievals for GPM, a Global Precipitation Measurement Mission.
