| Definitionskos:definition | This OGC Testbed 12 Engineering Report (ER) discusses the topic of implementing vector tiles in an OGC GeoPackage. This report builds on the general topic of vector tiling discussed in OGC Testbed 12 Engineering Report [OGC 16-068r4]. Since its public release in 2012, OGC GeoPackage has been getting increasingly popular within the geospatial industry for a variety of use cases, such as a means to package geospatial data for use on a mobile device and as a means to exchange geospatial data between two systems. The OGC GeoPackage standard currently specifies requirements (rules) for storing raster tiles and vector (simple) features. This Engineering Report proposes an extension to the supported data types by introducing an implementation for vector tiles. While tiling and the use of multiple levels of details are a proven technique for accessing and visualizing raster data, it is less commonly applied for vector data. This is due to the increased complexity compared to raster tiling and lack of standardization on the topic. Yet, implementing vector tiles can provide the same benefits as for using raster tiles. Services can easily cache tiles and return them instantly upon request, without the need for any additional pre/post processing. Consequently, clients can get tiles very fast, ensuring fast and responsive maps. Using tiled, multileveled data representations, clients can always access the data most suitable for their current map location and scale. This avoids the need to load too much data, which can cause excessive memory usage and reduce overall performance. The goal is to enable systems to use OGC GeoPackage as a means to store and access vector tiles in an efficient way, similar to raster tiles. |
