This article demonstrates how to work with projects in MapTiler Desktop. It explains saving and loading project files in the MapTiler Desktop PRO version.
Since some of the application settings get saved with the project, they also get loaded with it. This means some of your settings may be overwritten by loading a project. Read more in the settings article.
A project in MapTiler Desktop is a work in progress process of turning an image into a map tile. You can set the default project files location in the application settings.
To save your work, click on "File -> Save project" in the main menu. Loading is similar: "File -> Load project", or double-click on the saved file in your file browser (make sure MapTiler Desktop is associated with the .mtp files).
The default save format is MapTiler Desktop Project file with .mtp extension. It consists of a set of commands for MapTiler Desktop. The file can be opened in any text editor and particular commands are here visible in a human-readable form, as in the example:
Moreover, it can also be executed by another installation of MapTiler Desktop. This can be used as an optimization method by selecting parameters and visual georeferencing done in a graphical user interface and rendering on a faster machine with more CPUs without a graphical user interface.
If you decide to start over while working on your project, you can start a new project using "File -> New project". If there are changes detected, you'll be prompted to save your unsaved work.
You can as well use shortcuts instead of choosing a command from the menu, "Ctrl + S" (Cmd + S on macOS) for saving a project and "Ctrl + N" (Cmd + N on macOS) for starting a new project.
