DEVELOPING WEBGIS FOR BUILDINGS IN NAGARI KOTO GADANG, AGAM REGENCY, WEST SUMATRA PROVINCE

Abstract

Some ASEAN countries, such as Malaysia and Thailand, have taken the initiative to use information technology (IT) to develop villages to realize Smart Village. Likewise, in Indonesia, one village in the province of West Sumatra, Indonesia, namely Nagari Koto Gadang, has begun to use IT in developing its community. This village is located in a strategic area that has the potential to change land use in the future. In the planning and development of a region's spatial layout, it is necessary to collect data on buildings contained in the area. Building data collection in Nagari Koto Gadang is still done using paper notes so that it is vulnerable to duplication or data input errors. Information regarding buildings in Nagari Koto Gadang can only be obtained at the village office during working hours by manually searching excel data. This information should be accessible anywhere and anytime. Therefore, we need a Web Geographic Information System (WebGIS) that can record and map buildings in Nagari Koto Gadang. The building consists of office buildings, health services, schools, mosques, Micro, Small and Medium Enterprises (MSMEs) and residents' settlement. With this WebGIS of buildings, the Nagari Koto Gadang government can display information on the availability or use of land that is useful for village planning and structuring. The WebGIS development of the Nagari Koto Gadang building consists of several stages, namely data collection, application development, and system testing. WebGIS of this building was implemented using PHP and JavaScript. The database used to store data was PostgreSQL/PostGIS. WebGIS of Nagari Koto Gadang building can be used to view, and search for information about office buildings, residential houses, and other buildings in Nagari Koto Gadang. The test results show that the functional of WebGIS of the building is following the needs of the government of Nagari Koto Gadang.
