Working with projects

A project in MapTiler Engine is a work-in-progress process of turning an image into a map tile. This article demonstrates how to work with projects, it explains saving and loading project files in the MapTiler Engine.

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.

New project

With “New project” action, you’ll be taken to the very beginning (workflow selection page) from any place in the application. Keep in mind, unlike the “Edit project” button available on the bottom panel after processing, this will clear the settings you performed within the project preparation (on different pages, not application settings), as well as your input data.

If there are changes detected, you’ll be prompted to save your unsaved work.

Save/Load project

To save your work, click on “File -> Save project” in the main menu. Loading is similar: “File -> Load project”. You can set the default project file location in the application settings.

This functionality is limited to the rendering workflow due to interoperability of the project files with the command line interface. That means, you won’t be able to load or save projects while being in uploading or merging workflow. 

By loading the project, your current work will be dropped and new input data \& settings will be loaded. 

File format and interoperability

The default save format is MapTiler Engine Project file with .mtp extension. It consists of a set of commands for MapTiler Engine. 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 Engine. 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.

Using shortcuts

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.
