The map layout also contains information that helps users orient themselves to the location and context of the information being presented 1 5 1 Rules for constructing map layouts Regardless of content or style all map layouts require certain features to contextualize the information presented The following are minimum features that should be included on all final maps 1 5 2 Legend defines the symbols or colors used on a map The legend should clearly define what each marker line type color or pattern represents Title easily identifiable descriptive text that indicates location and purpose of the map The title is the largest text on the layout but does not dominate the map itself Border a thick line drawn around the map that identifies exactly where the mapped area stops The border should be thick and the map should be centered within the border Scale a graphic bar that indicates the relative size of the map may not be necessary for all audiences Orientation graphic indication of which way is north This is commonly done through a north arrow Creating a map layout in Print Composer The print composer is a QGIS module separate from the map design window that allows users to design a map layout and export as an image or PDF In this scenario we will export the map as a jpeg image that can be pasted into a word document a powerpoint presentation or shared online 1 To open the Print Composer click
