Re:Earth is a programming-free Geographic Information System (GIS) platform that enables people to easily create/publish 3D maps with layered information on a web browser. No software downloading is needed. Plug-in tools for easy overlaying/manipulating of location-specific info. As an open-source platform, Re:Earth allows engineers to develop their own service products with it. It’s already used in Japan by clients in IoT, construction, and government.
