When you are looking at a map on a website or phone, you are looking at a composite of many different “Data Layers” where each layer has “features” that lets you interpret information on the map. Some layers contain the position of traffic signs while others show boundary lines of a city.
HERE Data Layers are a collection of features organized into a searchable set of data that can be queried and included in business decisions.
Most mapping vendors do not allow data layers to be made publicly available. HERE is releasing a subset of its layer data through the Freemium Developer Program for certain cities.
List of available layers:
The Administrative Divisions layer contains the hierarchy (for example Chicago, Cook County, Illinois, United States) and attributes for each administrative area in the HERE Map.
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 Buildings layer contains 2D building footprints with corresponding attributes ( like Height and BuildingType), representing man-made building structures.
Variety of water features (lakes, rivers, oceans, bays, and so on).
Content related to the physical coverage of the Earth (such as woodland, wetlands, grassland, desert, or glacier).
Content related to land use; it classifies areas of land for use by people.
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.
Places (also known as Points of Interest or POI) with their corresponding locals.
Road Network with topology and Navigable Attributes and Street Naming with Address Ranges.
Signs along the road used to inform the driver of specific road situations (such as warning signs, priority signs, or stop signs).
You can find more information about the available layers by going to this link to documentation. Freemium users are allowed to select one city and cannot be changed after selection. Pro users can select up to 2 cities.
HERE Data Layers is an extension to the HERE Developer Freemium account and provides raw GeoJSON map data that allows you to interpret and display additional context and relevance for your products.
The layers include features useful in modelling road networks such as speed limits, sign boards and enables use cases such as point-to-point routing, turn-by-turn navigation, advanced navigation for cars and trucks, business intelligence, planning and optimization, and much more.
The HERE Data Layer Features allows users to access GeoJSON map data via the HERE Data Hub and HERE Studio. You can utilize standard HERE Studio functionality to visualize GeoJSON map data; the DataHub API and CLI functionality to allow you to store, interact and retrieve the GeoJSON map data.
A HERE Data Layers will give you more control over what you show on a map. You can choose a specific layer or feature within a layer to display. For example, if you want to display only water bodies on a map, then choose
hydrography layer or maybe you just want to show the road signs and speeds.
In this tutorial, you will learn how to access, how to make a map and download the HERE Data Layers using HERE CLI.

If you are not able to see the project, click on the projects link as shown below.
In the image below you’ll see our project is named “Freemium 2020-03-31”. Next, we will select “Freemium 2020-03-31”.
To get the HERE Data Layers. Firstly, you need to select the layer of your choice in HERE Data Layers section as shown:
Then you need to select a desired city as shown below:
Then click on
Save to Data Hub button. It will show a popup box to check the confirm selection to upload data to studio.
Note: It will ask for the credit card information. Proceed for the payment page and add the card details. We will not charge for that when you are a
Freemium user. For more inofrmation about the plans, please check out the link
Yes to upload data to Data Hub. It will display a popup box for the confiramtion.
OK to use the Data Access Options. There are three different ways to access data. Now, I will show how to access data using HERE Studio.
Use HERE Studio, an interactive, visual, web-based application for accessing data in Data Hub and creating maps within minutes - without any code.
The Data Hub CLI is a command line interface which uses an interactive command window to enter instructions. Understand and use Data Hub CLI commands to interact with Data Hub Spaces.
Here is the command to download using DataHub CLI:
here xyz show 'SPACE ID' -r > my.geojson

In this video, I will show you sample data set to upload data to DataHub and create a map using HERE Studio.
HERE Data Layers is continuously updated, and any changes are published biweekly as a new version. Whenever a new update is available, the Latest Version Available column is highlighted.
