s4a.js is a client-side Javascript library for rapid spatial application development based on the SDI4Apps OpenAPI GIS server platform
It extends OpenLayers, d3.js and a few other leading Javascript libraries - and provides users with the parts they need to put spatial functionality into their HTML5 applications
This library is intended for the users who would like to get maps into their applications without the workload of running a server, installing and maintaining software and learning the professional concepts of GIS.
