Map Layouts
Map Layouts Includes all of the elements of a stand alone map • Make the map the largest and most prominent element of the layout • Put a rectangular boundary around the map (called a neat line by cartographers) to help draw attention to it as the central element • Include a map title -The title needs to include information minimally answering the three questions what, where, and when. GIS 14
Map Layouts (Continued) • Include a legend for symbols placed in the lower-right or left of the layout -No need to label it Legend. Everyone will know what it is (this eliminates “chart junk”) • Include data sources • Ensure legibility • Include a graphic map scale if your audience is not familiar with the area shown • Do not include a north arrow unless the top of your map is not north GIS 15
Map Layouts (Continued) • Occasionally include other components as needed such as a data table listing, a frequency bar chart for the attribute of a choropleth map, or a photograph GIS 16

Map Scales
Dimensionless Map Scales • ratio that relates a unit of measure on a map to some number of the same units of measure on the earth's surface • 1: 25, 000 • tells us that 1 unit of measure = 25, 000 of the same units on the earth's surface • 1” on the map = 25, 000 inches on the earth's surface • one meter or one yard or one kilometer or one mile would represent 25, 000 meters or yards or kilometers or miles, respectively, on the earth's surface. GIS 23
Large and Small Scale Maps 1: 5, 000 is large scale Large Scale Map 1: 50, 000 is small scale Small Scale Map GIS 24
