| Popis: | The European Union Initiative “Infrastructure for Spatial Information in the European Community” (INSPIRE), aims to ensure that spatial data infrastructures (SDI) of the members states follow common Implementing Rules (IR) for specific areas such as interoperability. SDI are considered as strategic infrastructures to develop environmental policies through the use of Geographic Information Systems (GIS). This team suggests connectivity as a crucial condition to allow network analysis with GIS.Vector GIS have their operational fundamentals based on Graphs Theory and this fact makes them suitable for networks analysis. In this paper, various methodologies, techniques and tools are proposed within the scope of the GIS, in order to be taken into account in the previous design of a network layer, in the proposal for rules of connectivity and in considerations about topology. Simple networks are logically a primary level when the goal is analyzing multimodal networks, where complexity of connectivity increases dramatically. As far as intermodality is a strategical issue in UE policies, this paper aims to highlight the importance of assessing the quality of connectivity and how to solve inconveniences about a lack of it. Several GIS software platforms have been chosen using a common language based in the Graphs Theory, in order to ease the use of the proposed methodology with other tools. The Spatial Data Infrastructure of Andalusia (IDEA) is used as an example, as it is one of the most advanced and experienced public SDI in Europe. However, this SDI has presented connectivity faults in a roads network layer not allowing an efficient use by users and researchers from this region. |
