Elasticsearch 7.15 introduces a vector tile search API that enhances the efficiency of rendering geospatial data by generating vector tiles from data stored in Elasticsearch. This API addresses previous challenges in visualizing high volumes of geospatial data by implementing vector tiles and improving map tiling through a fixed grid system, simplifying geometries according to scale, and reducing data transfer. Vector tiles, encoded using Google protobuffers, provide a more efficient file format than GeoJSON and can represent aggregated views of data for easy rendering in map applications. The API allows users to define query parameters to control the information encoded in vector tiles and supports integration with Elastic Maps, as well as third-party applications like OpenLayers and Mapbox. The API also facilitates the building of a tile map service (TMS) and custom applications, ensuring secure deployment practices and enabling the use of vector tiles in web and mobile applications.
