WMS Integrator: continuous access to neighboring WMS

Resumen

The INSPIRE Directive, and SDI initiatives, promote that geographic data (GI) is updated and maintained in the most appropriate level or who is responsible. This fact motivates the emergence of many map services (WMS) that offer the same data in different geographical contexts. The atomization of WMS, for geographic domains, difficult the use for users interested in a topic: they must search for WMS, select layers and handle overlapping. This poster presents a facilitator node that manages WMS: URLs, layers, CRS, formats and versions, and offering a seamless WMS that integrate horizontally and vertically layers offered by WMS cascaded. The most important contributions of developed facilitator node (WMS-integrator) are the ability to: carry out some verifications, requests to the different WMS versions, mask spatially responses by boundaries polygons and merge the responses to finally deliver a single image as result that avoid data overlapping
