基 金:DGGS are supported by both the Open Geospatial Consortium (OGC) and the International Organization for Standardization (ISO) TC211 standards (OGC Abstract Specification – Topic 21 ISO 19170-1). These published specifications support 2D equal-area DGGS of the Earth’s surface. Current work led through both OGC and ISO/TC-211 is drafting standards to specify 3D (3D & equi-volume) 4D (spatio-temporal) and axis-aligned DGGS as well as OGC API DGGS interface encodings for DGGS infrastructures. The continued effort to develop international standards for DGGS will support the implementation of standardised interoperable Global Reference Grid Infrastructures that can support efficient and scalable integration of Big Earth Data across multiple organisations around the world
主 题:operations simplified partition
摘 要:The emerging field of Discrete Global Grid Systems(DGGS)provides a way to organise,store and analyse spatio-temporal data at multiple resolutions and scales(from near global scales down to microns).DGGS partition the entire planet into a discrete hierarchy of global tessellations of progressively finer resolution zones(or cells).Data integration,decomposition and aggregation are optimised by assigning a unique spatio-temporal identifier to each *** identifiers are encodings of both the zone’s location and its *** a result,complex multi-dimensional,multi-resolution spatio-temporal operations are simplified into sets of 1D array and filter operations.
