Mappen is a free, open-source map editor for Windows and Mac. It’s easy to use, and can be used to create maps of your own neighborhoods or cities. To start Mappen, open the program and click on the “New Map” button. You’ll be asked to choose a location to start from. You can either choose a location you’ve already created or you can create a new one. Once you’ve chosen your location, click on the “Create Map” button. Mappen will start creating your map. You can change the size of your map and add features such as streets, squares, and other public places. If you want to share your map with others, you can do so by clicking on the “Share Map” button. This will open up a dialog box in which you can select how many people should be able to see your map at once and how long they should have to wait for their turn.
