Introduction

This document provides information on the following products.

Administrative Divisions

The Administrative Divisions product contains the hierarchy (for example Chicago, Cook County, Illinois, United States) and attributes for each administrative area in the HERE Map.

The following list describes additional information and specifics of the layer:

  • Administrative Areas names in various languages and transliterations.
  • Postal code information.
  • Administrative metadata information like the local currency and language, applicable time zones and daylight-saving time, and more.
  • Disputed Area coding is included in the Administrative Places as an alternate administrative structure.
  • The Administrative Divisions structure is constructed based on admin, zone and postal information in the HERE Map. The Administrative Areas layer is linked to the Places and Navigable Roads layers by the Administrative Context that is included in each Road feature and Place. A complete overview and comprehensive description of attributes is provided in the HERE Map Content catalog data specification.

Buildings

The Buildings layer contains two-dimensional building footprints with the corresponding attributes (like Height and BuildingType), representing man-made building structures.

The following list describes additional information and specifics of the layer:

  • Building footprints can be single or multi-polygons. In case of multi-polygons, the footprints are grouped in the same feature.
  • A building footprint polygon can include holes.
  • Building footprints are provided with a name where available.
  • Categories are provided for each building to identify the general usage of the building, for instance in case of residential building, historical building, and many others.

Cartography

The Cartography product contains the following layers.

Hydrography

The Hydrography layer includes cartographic content representing water features of various types, e.g. Lakes, Rivers, Bays, Oceans and more. The Hydrography content is static and can be represented as polygonal or linear geometry objects for map rendering.

The following list describes some examples and specifics of the layer:

  • Examples: ocean, bay, lake, river
  • Geometry is linear or polygonal
  • Features are Spanning - combined coverage of all hydro features should include all surface water on Earth with no gaps
  • Features are optionally named

Land Cover

The Land Cover product primitive publishes cartographic content related to the physical coverage of the Earth and includes information like woodland, wetlands, grassland, desert, or glacier.

The Land Cover content is relatively static and is provided as polygonal information.

The following list describes some examples and specifics of the layer:

  • Examples: woodland, grassland, desert, glacier
  • Data Type: polygonal
  • Features are spanning - the entire land surface of the Earth can be categorized
  • Features are optionally named - well-known Land Cover (e.g. Sahara Desert) are named
  • Features are not necessarily aligned - Land Cover in not man-made and does not require alignment with man-made features

Land Use

The Land Use product primitive publishes cartographic content related to the functional usage of the land, it classifies areas of land for use by people. The Land Use is more dynamic than Land Cover or Hydrography.

Land Use is classified according the to how the area of land is designated for use by people.

This layer is used to display the map at high zoom levels and to show the spatial extent of places.

The following list describes some examples and specifics of the layer:

  • Examples: shopping centre, airport, amusement park
  • Data Type: polygonal
  • Features are not necessarily Spanning - some land is not dedicated for use by people
  • Features are optionally named
  • Features are aligned - Land Use features should align with each other, as well as hydrography and man-made features (road network, railway).

Destination Signs

The Destination Signs product primitive includes directional signs as published along roads to inform the driver of destinations the road is heading to.

The Destination Signs primitive lists the various destinations visible on a sign shield, and relates such destinations to a specific path in the road network.

The Destination Signs layer publishes textual and graphic information posted on signs along roads. The signpost information can be used for route guidance (both audible and graphical/textual guidance) and map display.

The Navigable Roads layer represents roads with their corresponding attributions. The Roads publishes geometry for the center line of the road, and includes attributions to make the road navigable.

The following list describes some other features included:

  • Street naming with related address range information
  • Administrative referencing
  • The From and To nodes (objects with geometry and attribution) to have the ability to create a Road topology network.

Places

The Places layer contains global, fresh, comprehensive and consolidated places for over 400 categories. Place attributes include location, name, address and phone number.

Rich attribution (where available) provides more details about places, such as hours of operation, food types, brand and more.

Each place has a quality score, providing an indication of its relative accuracy and completeness, allowing you to select places with the quality level that you need for your application.

Traffic Restrictions

The Traffic Restrictions product primitive represents multi-link condition coding applicable to the Navigable Road and is used to model restrictions to specific maneuvres in the road network.

The Traffic Restrictions primitive initially includes Turn Restrictions and Permitted Driving Maneuvres. Over time additional multi-link restrictions can be added to the Relation map primitive. Examples of such restrictions are Gates or Bifurcations.

Traffic Signs

The Traffic Signs product primitive represent signs along the road network used to inform the driver of specific road situations.

The Traffic Signs typically are used to communicate specifics on the road conditions, traffic regulations, safety issues or other traffic-related events to the driver.

Traffic signs includes things like Warning Signs, Priority Signs, Stop Signs, or other types of road infrastructure.
