Introduction to Spatial Data Infrastructures and Web Services. The WMS Display Service and the Geographical Information Metadata

Abstract

Nowadays, most of our information and data for consequent treatment comes from Spatial Data Infrastructures and web services. Also, much of the research developed serves to feed those spatial data infrastructures as well as several web services and vice-versa. In this regard, it becomes essential to understand the basic concepts of some of the involved Geographic Information Systems (GIS) and their tools, as is the case of the World Map Services (WMS) and the metadata. This work will briefly explain those concepts and use the open-source GIS software Quantum GIS to exemplify a practical use of such tools.
