OGC Moving Features Encoding Part I: XML Core is represented by an XML data encoding for moving points and their trajectories. As with GEOMETRY, we recommend that when you have very large polygons, but are doing queries in small areas, you "denormalize" your geometric data into smaller chunks so that the index can effectively subquery parts of the object and so queries don't have to pull out the whole object every time. The OGC Conceptual Model Standard specifies the representation of virtual 3D city and landscape models. Both formats are encoded using JSON and binary ArrayBuffers (ECMAScript 2015).
