Google My maps

https://www.google.com/maps/about/mymaps

Here you can create and store maps created with routes and labels. Also you can store cards created by someone else.

In fact, we store a portion of the Google map with the layer we built.
We'll set point A and point B, Google builds a route, we can change the route with a mouse, and add our tags to it. For example, we can specify the destination of the route and key locations along the route, etc.
