Map Essentials• Direction Indicator (True, Magnetic, Grid)• Scale (Miles, Meters, Feet)• Legend– Title, Purpose– Explain Symbols– Follow Convention
• Graticule (Latitude-Longitude, UTM)• Index map

Map Design
• Landscape or Portrait?• Legibility– Symbol and text size– Avoid clutter– Color Scheme

Good Idea, Bad Design
![Page 29: Maps at Varying Resolutions and Scales](https://reader036.fdocuments.us/reader036/viewer/2022062323/56816149550346895dd0c7ed/html5/thumbnails/29.jpg)
Why It’s a Bad Map
• Poor Color Scheme– Okay, it’s putrid
• Does not distinguish between low incidence and no data
• No information on number or location of data points
