Adding SOS Core & transactional profiles support to a web thin client

Abstract

In a world where day by day more web applications provide plenty of creative and interesting services, it is important to create similar applications to distribute and spread geographic information easily. In this context, it becomes necessary to develop new web clients capable of connecting with remote geospatial servers, request and retrieve data and allow the user to make a set of operations or just present him or her those results overlaid on a map. Sensor Observation Services (SOS) is a protocol that defines how to interchange geospatial data between a client and a SOS server by using a set of operations classified in three profiles: Core, Enhanced and Transactional. In this document, it is possible to find a description of the software engineering process to create a web client supporting the operations of the Core & Transactional profiles that a user may use without needing additional software.
