SVGMap is a de-centralized, hyper-document based web mapping standard with open source front-end (webApps) and back-end implementations based on SVG. In particular, it has the good ability to integrate various map contents on the web through client-side inter-operability and the ability to visualize big data on a map.
There are already implementations of SVGMap with over 15 years of practical experience for enterprise. And, as of 2024, continuous improvement is ongoing.
