@here/harp-omv-datasource

Overview

This module provides the implementation of HERE's Optimized Map for Visualization (OMV) Datasource.

This format follows the Vector Tile Specification. This JSON format contains geometries, such as points and lines that define polygons, labels, such as road names or city names, and other kinds of data that are typically passed to a renderer to draw a map.

Each tile is encoded using Protobuf.

REST Clients

HERE Vector Tiles

REST service implemented with APIFormat.HereV1 in OmvRestClient.ts if you want to use AuthenticationTypeBearer by default, if you want to use APIKey you can use APIFormat.XYZOMV.

You can find more about the different access methods here.

The HERE Vector Tile Service allows you to request tiles containing vector data using content from the HERE Open Location Platform.

HERE provides global coverage and updates the data continuously. For more information about our map content, see the HERE Map Content Guidelines.

HERE XYZ

REST services implemented with APIFormat.XYZMVT, APIFormat.XYZJson and APIFormat.XYZOMV in OmvRestClient.ts.

The HERE XYZ Services offer three variants:

• MVT: offer Open Street Map Data tiles in MVT Format.
• JSON: offer Open Street Map Data tiles in JSON Format.
• OMV: offer HERE Data tiles in OMV Format. The data source is the same as in the HERE Vector Tiles.

You can find more about the HERE XYZ Services here.
