interessante novita'; forse nel prossimo futuro una drastica rivoluzione potrebbe cambiare radicalmente le modalita' di georeferenziazione delle informazioni.
nei giorni scorsi OGC (Open Geospatial Consortium) ha ufficialmente approvato la specifica DGGS (Discrete Global Grid System) [1], [2] [1] http://www.opengeospatial.org/pressroom/pressreleases/2656 [2] http://docs.opengeospatial.org/as/15-104r5/15-104r5.html ----- "The goal of DGGS is to enable rapid assembly of spatial data without the difficulties of working with projected coordinate reference systems. The OGC DGGS Abstract Specification standard defines the conceptual model and a set of rules for building highly efficient architectures for spatial data storage, integration and analytics." "DGGS will provide the capability to properly integrate global geospatial, social, and economic information. It also allows communities with data attributed to fundamentally different geographies to integrate this information in a single consistent framework" "DGGS will revolutionise the way we perceive, work with, and visualise spatial information." "DGGS are a technology that allow the harmonisation of raster, vector, and point cloud data in a common, globally consistent framework – enabling the spatial industry to overcome some key challenges presented by traditional GIS approaches; namely, the ‘raster-vector divide’, as well as the use of map projections" "DGGSs represent the Earth as hierarchical sequences of equal area tessellations on the surface of the Earth, each with global coverage and with progressively finer spatial resolution. Individual observations can be assigned to a cell corresponding to both the position and size of the phenomenon being observed. DGGS come with a standard set of functional algorithms that enable rapid data analysis of very large numbers of cells and, by their very nature, are well suited to parallel processing applications at multiple spatial resolutions." "DGGS represents the paradigm shift that will allow us to overcome some of the critical barriers preventing us from realising the true potential that Big Data promises to deliver” ciao Sandro _______________________________________________ Gfoss@lists.gfoss.it http://lists.gfoss.it/cgi-bin/mailman/listinfo/gfoss Questa e' una lista di discussione pubblica aperta a tutti.
