Understanding the steps involved in HD map-making and seeing them come alive by visualizing them using a 3D-map rendering engine is like hitting two targets with one arrow.
Walk away with visualization of LiDAR point-clouds collected by HERE cars, raw features extracted from LiDAR (Light Detection & Ranging) imagery and the final HD-map.
This will be achieved using an open-source 3D web-map rendering engine – harp.gl

Download and install Node on your machine: https://nodejs.org/en/download/ Use the latest LTS Version: 12.18.3
Add the NPM registry to your config with the following command:
npm config set registry http://registry.npmjs.org
URL: https://github.com/heremaps/devrel-workshops/tree/master/
The repository we would be working on is placed within the folder structure harp.gl/grace-hopper-2020. Follow the instructions to set up the application after navigating to this path.
The initial app set up for all three steps has already been done for you. The workshop is divided into three steps under the folders:
- point-clouds
- intermediate
- hdmap
You will be working off of the 'initial' folder during the workshop.
Go to https://developer.here.com/sign-up?create=Freemium-Basic&keepState=true&step=account
- Create an account using your details
- Generate an app under the 'REST' section
- Create an API Key
- Replace the new api key in the file: ./apikey.ts
Run this command in each of the three sub-folders mentioned below
npm install
- ./point-clouds/initial
- ./intermediate/initial
- ./hdmap/initial
Go to ./point-clouds/initial folder and run the app using the command below:
npm start
You should be able to see a map as shown below:
