Places (Search) API Developer's Guide

Tiles Entrypoint

The tiles feature allows you to request place recommendations for areas of the map that are displayed to the user by requesting place tiles covering individual map tiles, in the same way that visual map data can be be requested a tile at a time. As the user moves the map, you request place tiles covering newly displayed areas. Place tiles requests are more cacheable than requests to the explore endpoint, resulting in better response times and the user experience in applications that allow map panning, and enabling us to serve them through a CDN, which can improve load times for all users. A place tile looks like a normal explore result only that the area is defined by a map tile.

The Tiles Entrypoint retrieves a list of base URLs which encode the criteria specified in the request, and which can be used to construct URLs for individual place tiles. A list of base URLs is provided so that you can overcome typical web browser restrictions that limit the number of parallel requests to a single domain, e.g. by random or round-robin selection of a base URL when requesting individual tiles.

To request an actual tile, the tile address (zoom, column and row) has to be appended to the base URL. Zoom, column and row parameters follow the tile addressing schema of the HERE Map Tile API.

The Tiles Entrypoint is a Places (Search) API Premium entrypoint.

Note:

This is a premium feature. Contact your HERE representative or contact us through developer.here.com to request the appropriate license if this feature is not already covered by your agreement.
