On the Kingdom Come: Deliverance subreddit, a user named rogerhnn has been diligently working to create an interactive map for the medieval RPG. The map is now live and viewable in your browser. It's zoomable, and you can add your own map markers that will be saved in your browser history (if you clear your cache, your custom markers will be removed).

You can toggle on and off the various icons: city names, camps, baths, caves, grindstones, taverns, millers, herbalists, etc. To add your own local marker, just click on the map, then click Add Marker. Choose the icon you want (which include a few general, all-purpose icons like arrows, stars, and exclamation marks) and label it. It's a good way to keep track of interesting or useful locations you come across that might not appear on your in-game map (for instance, places you spot certain herbs for alchemy, or a shop selling something you can't afford but want to buy later, or an area you plan to explore further for treasure).
