For this reason, it is necessary to have a Geographic Information System (GIS) that is able to display the web-based agglomeration of industry and trade to ensure the quality and smooth flow of information about the existing potential. For this reason, the research that will be carried out uses the Research and Development (R&D) method, while the system development model used is Waterfall.
