Requesting a HERE Map Image With HTTP and Golang

At events, I often get asked about generating map images using server-side technologies, or basically any technology that isn’t client facing like JavaScript, Android, and iOS. For example, a common request is around providing criteria for a map to be generated as part of a script, report, or similar. Let me show you how.
HERE does have a REST API known as the HERE Map Image API and it is consumed through HTTP requests. This API can generate standard map images or map images that include map objects such as polylines, polygons, or similar. Essentially, if you can produce it with the JavaScript SDK on an interactive map, you can produce it on a map image.
