Start using []( or read on for more documentation! ## Exporting Once you're map is complete, you can download it as a single image in JPG and other formats. Read about the new Cloud exporter here: Learn more about [exporting maps in MapKnitter here](/mapknitter-exporting). ## Activities [activities:mapknitter] **** ## Questions [questions:mapknitter] **** ### Advanced * [Decisions with distortions](!) - Learn about the design process of stitching maps when images are highly distorted or include tall buildings.
