In this context, the French research program “GEOBS: Spatial Data Infrastructure in the informational governance for environment” (2015-2018) led by the French National Centre for Scientific Research (CNRS) considers SDI as a real object of study for a better understanding of the flows of environmental information. For this purpose, we are developing a prototype observatory based on content and...

Shock ripples and shock–discontinuity interactions (SDIs) have long been proposed to explain the frequent occurrence of high-speed jets (HSJs) in magnetosheath; however, there is no direct observational evidence for either them occurring near a shock. Herein, we report large-scale, long-duration undulated quasi-perpendicular shock surface that capable generating HSJs. Based on curvatures estima...

In this paper, we consider the problem of allocation Emergency Vehicles (EVs) to Rescue Centers (RCs). The objective is improve operational response Fire and Services (SDIS) in France. More precisely, focus on mid-term management, process redeployment EVs RCs according evolution requirements. At level decision, do not have information accidents. We only used available simultaneity Based Hurwicz...

Abstract. Clearinghouse is a major component of Spatial Data Infrastructures (SDIs), and plays key role in the discovery, access, exchange geospatial data via distributed network. Traditionally, main emphasis Geospatial Networks (GCNs) are availability accessibility data. Such approaches, however, have failed to address real-world problem solving decision-making. The lack general solution for k...
