Analysis and design of web-geographic information system for tropical diseases-prone areas: A case study of East Java Province, Indonesia

Analysis and design system in this paper is used to model Web-Geographical Information System (Web-GIS). The results can be used to create Web-GIS applications that are able to identify prone-areas to tropical diseases in East Java of Indonesia, using Multi-Attribute Utility Theory (MAUT). This Web-GIS information system includes the distribution of the affected areas, endemic areas, epidemiological inquiry and tropical diseases-free areas. Web-GIS analysis process consists of: describing requirements system, outlining the need of spatial data (layers) and attribute data tables, create a process model with tiered diagram and data flow diagram that describe the process flow of a Web-GIS system. System design process by making Conceptual Data Model (CDM) serves to describe the needs of spatial data and attribute data in a database system. CDM is generated and produces Physical Data Model (PDM). PDM contains the metadata structures of the spatial data and attribute data that will be processed and stored in the Web-GIS application program. Geoprocessing Layers are implementation of the analysis process and design system, processing layer by buffering, union, and intersection layer techniques. The layer is generated from geoprocessing and processed by entering parameters in MAUT method to result the identification of tropical diseases prone areas.
