HERE.GpsSimulator

The example code demonstrates how to use the HERE API to create a route between two points and then simulate GPS pings along the route and a specified interval. The output is written to a JSON file. The code sample is written for truck routing but can be easily adapted for other modes of transportation.

Example command line:

HERE.GpsSimulator generate --origin "600 E Grand Avenue, Chicago IL" --destination "1300 Fox St Denver CO 80204" 
--departuretime "11/21/2021 11:00 AM" --grossweight 75000 --interval 00:15:00 --axlecount 5 --trailercount 1 
--trucktype tractor --routingmode short --regulation true --lastrest 2 
--outputfile "%USERPROFILE%/Desktop/gps-data.json"

Type HERE.GpsSimulator -h for parameter info. You will get the output shown below.

HERE.GpsSimulator

Usage:
HERE.GpsSimulator [options] [command]

Options:
	--version       Show version information
	-?, -h, --help  Show help and usage information

Commands:
	generate  Generates GPS pings from a specified origin point to a destination point.

For specific command help, type HERE.GpsSimulator -h [command]. For example, -h generate gives the output shown below.

generate
  Generates GPS pings from a speified origin point to a destination point.

Usage:
  HERE.GpsSimulator [options] generate

  -r, --regulation <regulation>               Specifies whether US driver regulations should be observed. The default is True.
  -h, --lastrest <lastrest>                   Specifies the number of hours since the driver's last rest before picking up the load. The default is 0.
  -f, --outputfile <outputfile>               Specifies the full path to the JSON output file.
  -?, -h, --help                              Show help and usage information                                 Show help and usage information

HERE.Api and HERE.Api.Example

Example code to Authenticate to the HERE.com REST API in C# using OAuth 1.0 and OAuth 2.0. Also demonstrates a map request and Geo Code request.

using System;
using System.Diagnostics;
using System.IO;
using System.Net.Http;
using System.Net.Http.Headers;
using System.Threading.Tasks;

namespace Here.Api.Example
{
	class Program
	{
		static async Task Main(string[] args)
		{
			//
			// Go to your project at here.com and create OAuth 2.0 (JSON Web Tokens) credentials. This will prompt you
			// to download a file named credentials.properties. Copy it to this project folder.
			//
			HereCredentials credentials = HereCredentials.FromFile("./credentials.properties");
			IHereTokenFactory hereTokenFactory = new HereTokenFactory();
			HereToken token = await hereTokenFactory.CreateTokenAsync(credentials);

			//
			// Get a sample map image.
			//
			using (HttpClient client = hereTokenFactory.CreateHttpClient(token))
			{
				byte[] imageData = await client.GetByteArrayAsync("https://1.base.maps.ls.hereapi.com/maptile/2.1/maptile/newest/normal.day/13/4400/2686/256/png8");

				//
				// Save the image to a temporary file.
				//
				string tempFile = $"{Path.GetTempFileName()}.png";
				await File.WriteAllBytesAsync(tempFile, imageData);

				//
				// Open the image with the default system viewer.
				//
				Process.Start(new ProcessStartInfo(tempFile) { UseShellExecute = true });
			}

			//
			// Use the GeoCode service to find and address.
			//
			IHereGeoCodeService hereGeoCodeService = new HereGeoCodeService();

			(HereGeoCodeList result, HereApiError error) = await hereGeoCodeService.FindAddressAsync(token, new HereAddress()
			{
				Street = "600 E. Grand Avenue",
				City = "Chicago",
				State = "IL"
			});

			if (error == null)
			{
				Console.WriteLine($"Result: {result.Items[0].Title}, {result.Items[0].Id}");
			}
			else
			{
				Console.WriteLine($"Error: {error.Title}");
