“…However, if the weight is> 0.10, an inconsistent assessment has occurred or the sensitivity value is poor, meaning that the MCDM calculation must be repeated before proceeding to the spatial analysis, (5) Spatial analysis is the aggregation of relative weights that have been produced in the previous stage to produce composite weights as the final score in spatial decision making. The geographic information system method go through stages, namely: (1) creating conceptual model using matrix which presenting linkages between the resulting feature, users and resolution, (2) structuring functional model using matrix which presenting the relationship between resulting feature and graphical information entity, (3) collecting data which is consisting of graphical and attribute data,(4) data categorization based on the type and level of accuracy of the data, (5) digitizing base map refers to the conceptual and functional models, (6) entering attribute data with data structures refers to the conceptual and functional models, (7) operating spatial analysis of several thematic layers with arithmetic operations, namely boundary intersection, union, inverse, area, perimeter, abscissa center, ordinate center, etc, (8) programming to build systems of interaction with users, (9) trials to stakeholders, (10) revision, (11) implementation.…”
