1.11 Vector Tiles

Oracle Spatial provides support for generating vector tiles from spatial data in database tables. The vector tile format is designed for highly efficient streaming of spatial data to map visualization clients.

Vector tiles contain geometry and attribute data in a compressed binary format covering square areas defined by a tiling scheme. In a tiling scheme, the world is divided into square tiles identified by X and Y ordinates at each of a predefined set of zoom levels. Modern mapping clients are designed to consume spatial data from vector tiles and style information from style sheets. This affords tremendous flexibility and agility by allowing a single vector tile dataset to be leveraged for numerous map styles.

Oracle Spatial supports the generation of vector tiles from spatial data in tables with the SDO_UTIL.GET_VECTORTILE function. Vector tiles may be generated based on either the Google or TMS tiling scheme.
