These APIs include style elements to request the application of specific styles to data, including vector tiles. The OPF Thread also developed Web APIs that complement and upgrade existing OGC Web Services (e.g., WMTS and WMS) with OGC APIs for Maps, Tiles, and Images. Testbed-15 OPF developed a framework that allows applying styles to maps, raster, and vector tiles. In addition, VTP-1 developed a conceptual model for tiled feature data. The effort also developed a draft WMTS Styles API and a prototype OGC API for Styles. These extensions delivered VTP-1 supported web clients, desktop application clients, and mobile clients with support for offline situations. VTP-1, the first phase 1 of the Vector Tiles Pilot, has successfully developed and delivered Vector Tile (VT) extensions for the OGC API - Features specification (formerly named Web Feature Service 3.0), Web Map Tile Service (WMTS) and GeoPackage in collaboration with industry partners. The VTP-2 initiative built on the previous Vector Tiles Pilot (VTP-1) efforts to visualize geospatial vector data on different client types, and on intermediate results stemming from the Testbed-15 Open Portrayal Framework (OPF) thread. There are seven videos that are on the OGC Youtube Channel for the Vector Tiles Pilot Phase 2: OGC Vector Tiles Pilot 2 Summary Engineering Report - 19-088 Vector Tiles Filtering Language Engineering Report - 19-084 Tile Set Metadata Engineering Report - 19-082 All Reports will be linked here when approved for public release: There are three Engineering Reports that have been generated from the Pilot.

VTP-2 conducted thorough testing of the OGC APIs for Maps and Tiles, as developed in Testbed-15, and further advanced support for vector tiles. The initiative also tested styled vector tiles with multiple data sources, perspective views, opacity, color backgrounds, imagery backgrounds and day/night display conditions.

All APIs and service types further supported the vector tile metadata model and filtering language, the two other essential work items of VTP-2. The feature and tile servers included WMTS, OGC API – Features, and OGC API – Tiles provided support for map projections other than Web Mercator. The objective of Vector Tiles Pilot Phase 2, was to deliver a consistent, interoperable online/offline architecture for vector tiles based on feature and tile servers, and GeoPackage. The Vector Tiles Pilot Phase 2 developed new capabilities to deliver a consistent, interoperable online/offline architecture for vector tiles based on feature and tile servers, and GeoPackage.
