OGC seeks public comment on Core Tiling Conceptual and Logical Models Abstract Specification Topic
Candidate Abstract Specification Topic defines a conceptual model for tiling space of any number of dimensions, as well as a logical model for tiling 2D space.
21 January 2020: The Open Geospatial Consortium (OGC) is seeking public comment on the Abstract Specification Topic ‘Core Tiling Conceptual and Logical Models.’ The Abstract Specification defines a tiling conceptual model as well as a logical model for tiling 2-D planar space based on the conceptual model.
Numerous OGC standards specify some type of tiling scheme. These standards include Web Map Tiling Service (WMTS), CDB, and GeoPackage. There have also been a number of OGC Innovation Initiatives focused on tiling and tiling schemes. However, a general tiling conceptual model and related logical model for two-dimensional Euclidean (aka planar) space - the most common tiling approach for geospatial technologies - have not been defined.
The general tiling conceptual model described in the Abstract Specification is applicable to space with any number of dimensions. The conceptual model makes no assumptions regarding content, use cases, implementation scenarios, or how the space is to be tiled.
As one or more logical models are required...
