gsc-sos.js

gsc-sos.js is a JavaScript library that encapsulates calls to a web service with SOS 2.0 implementation. Communication messages are XML formatted. The code is agnostic JavaScript, with no dependencies on other javascript libraries and it has the same 52North SOS client front-end to facilitate integration and evolutive development.

All functions handled the request to capabilities, so it is not necessary call it before any request like "getOffering", "getFeatureOfInterest" or "getObservation”.
