Taiwan is densely populated with limited land, making natural resources precious. Social issues such as urban-rural disparity, population aging, housing justice, and sustainable environmental development are key topics in modern life. By utilizing MIS, GIS, AI technologies, and Apps, we assist multiple counties and cities across Taiwan in implementing smart management, optimizing various business processes within the city. We introduce GIS 3D and 2D technologies to provide visual and spatial decision-making information, integrating resources of people, events, and objects to create a more humanized smart city management.
