Global Spatio-Temporal Search: NEH Funded Enhancements to WorldMap
Though millions of geo-service layers exist just a click away, there is no good way to discover most of them. In the early days of the web it was hard to find a web page; this situation holds today for most geo-data.
With a grant from the National Endowment for the Humanities, the CGA is building a platform to create, maintain, and deploy a global public registry of web map services, and has developed a new visual interface to support searches by time and space. The technology can scale to millions, even billions of objects.
The registry will expose an API to enable any mapping system to find and bind to any layer in the registry. The platform is open source.
