DEPARTMENT OF GEOGRAPHY UNIVERSITY OF FLORIDA PHYSICAL GEOGRAPHY LAB. - GEO 2200L Lab 8: Topographic Maps Total: 40 points Primary Objective: As you complete this lab, you will learn how to read topographic maps, learn the symbols and coordinate systems associated with topographic maps, and understand the importance and history of creating topographic maps. Part One: Go to the following website: 1. What is a map (please provide a complete definition)? (1 point) A map is a diagrammatic representation of an area of land or sea showing physical features, cities, roads, etc. 2. What is a topographic map? (1 point) A topographic map is a two-dimensional representation of a portion of the three- dimensional surface of the earth. Topography is the shape of the land surface, and topographic maps exist to represent the land surface. 3. Why is a legend necessary for most maps? (1 point) It gives you the information needed for the map to make sense. Maps often use symbols or colors to represent things, and the legend explains what they mean. In the table of contents on the left hand side, click Using Topo Maps and Map Scale to help with the next couple questions. There are seven rules that topographic maps have to obey (you can enlarge the figure on the right hand side to see examples of each rule). Using the principles of those rules, look at the contour map below and provide answers to the following questions. (Contour intervals are in feet, red numbers represent pointers, while black and brown numbers represent elevation). 1. Look at the slopes, A – B and C – D (represented by dashed [ - - - - ] lines and state which line represents the steeper slope. A -- B

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
