# Node-RED HERE Navigation Routing Dashboard
HERE Navigation Routing API Example on a Node-RED Dashboard
Use the [HERE.com Routing APIs](https://developer.here.com/documentation#routing_and_navigation_section) to build a map navigation dashboard and plot the route on a [Node-RED](https://nodered.org) Dashboard. Use the [Watson Text to Speech](https://cloud.ibm.com/docs/text-to-speech?topic=text-to-speech-about#about) service to narrate the route.
This example flow and Node-RED Dashboard might be useful as part of a [Call for Code](https://developer.ibm.com/callforcode/) solution that uses HERE Technologies APIs. Natural disaster applications could guide someone to safety.
### Prerequistes
- [Install Node-RED](https://nodered.org/docs/getting-started/) on your system or in the cloud
- This flow can be deployed to [IBM Cloud](https://cloud.ibm.com/registration) by creating a [Node-RED Starter Application](https://developer.ibm.com/components/node-red/tutorials/how-to-create-a-node-red-starter-application/)
- This flow requires Node-RED v1.1 or higher
- [Add the following nodes](https://nodered.org/docs/user-guide/runtime/adding-nodes) to your Node-RED palette
- [node-red-dashboard](https://flows.nodered.org/node/node-red-dashboard)
- [node-red-node-ui-table](https://flows.nodered.org/node/node-red-node-ui-table)
- [node-red-contrib-web-worldmap](https://flows.nodered.org/node/node-red-contrib-web-worldmap)
- [node-red-node-watson](https://flows.nodered.org/node/node-red-node-watson)
- Signup for a [HERE Developer account](https://developer.here.com)
- Signup for an [IBM Cloud](https://cloud.ibm.com/registration) account
- Create a (free) instance of [Watson Text to Speech](https://cloud.ibm.com/catalog/services/text-to-speech)
## Node-RED flow in this repository:
---
### A flow that displays a Navigation Route on a map
Get the Code: Node-RED flow for HERE Routing / Navigation
This flow has four sections:
1. The **Starting and Destination Locations / Geocode** section displays a Node-RED Dashboard form which prompts the navigator
to enter their starting location and ending destination. The flow then calls the [HERE Geocode Search API](https://developer.here.com/documentation/geocoding-search-api/dev_guide/index.html) to determine the latitude and longitude of the two waypoints.
1. The **Request Driving Navigation Instructions** section calls the [HERE Routing API](https://developer.here.com/documentation/routing/dev_guide/topics/introduction.html) to calculate the route between the two locations. It builds a table of these driving instructions and displays a summary of the route distance and driving duration.
1. The **Draw Map and Route** section moves the car on the node-red-contrib-web-worldmap as the navigator clicks on the **Navigation Preview** button.
1. The **Read the Driving Instructions** section determines if the mute slider is on / off and uses the Watson Text to Speech service to read the driving instructions aloud. Paste your Watson Text to Speech credentials into the node.
