Lab 2 Maps

Lab 2: Maps Instructions Watch the lectures and videos on maps in this module. After you have reviewed the lectures, notes, and the videos, use this document to work through your lab. Once you have finished answering all questions in this lab, submit your answers online in the link titled “Lab 2 – Maps Assessment”. After the due date, you will be able to review your lab and answers. When you first submit your lab, your score may appear low. Keep in mind for this lab and all others this semester that your lab instructor will need to grade your lab, especially the written responses. The computer can automatically grade and score multiple choice, matching, and true/false questions. Any written or essay responses will need to be graded by your instructor. Once your lab instructor grades those questions, your lab grade will be updated to the correct grade. Goals: o Understand maps and concept of scale o Interpret topographic maps and distance using fractional scales o Interpret topography from reading contour lines Key Terms / Concepts: Topographic Maps Physical Maps Thematic Maps Terrain Large-Scale Small-Scale Relief Discrete Data Continuous Data Slope Contour Lines Contour interval Elevation Percent Grade Isoline Types of Maps Maps are graphic and visual representations that illustrate spatial relationships. The word spatial pertains to or occupying space on Earth. There are different types of maps based primarily on their purpose. For example, a map that is good for road navigation would not be useful for traveling a mountain trail and would be less for determining population density. A physical map replicates Earth’s physical features (natural landscape) and provides visual information regarding the terrain (i.e., terra = Earth) in two-dimensional form such as slope, elevation, and orientation. Figure 1 represents a physical map of the United States. Can you locate the Appalachian Mountains, Rocky Mountains, the Great Lakes, and rivers?

When using a map, it is essential to understand its advantages, limitations, and faults. Scale can also be used to describe the detail of a map. Large scale maps show great detail over a small area (Figure 2). Small scale maps show little detail over a large area (Figure 3). Figure 2: Large Scale Map Figure 3: Small Scale Map 1. In what situations would you use a small-scale map? (1 point) 2. In what situation would you use a large scale map? (1 point) Figure 1 . United States Physical Map.

Thematic Maps A thematic map is designed to focus attention on a particular geographic pattern, feature, or phenomena at a location on Earth. The map will illustrate data connected to a place such as a city, a county, a state, a country, and a continent, and can be connected to a particular time. Common thematic map examples include climate types of the world, vegetation distribution in Ohio, earthquake fault lines, and population density in Northeast Ohio. The data on the maps are represented by different colors, shading, and symbols. The two types of data shown on a thematic map are discrete and continuous. Discrete data are represented on a map by a line, area, and a point symbol. Figure 4 shows a map of Hawaii showing the locations of large earthquakes using a point symbol as illustrated by a dot. Continuous data as shown in Figure 5 represents numerical values within the area of interest on a map. The continuous lines shown are often called isolines that connect points of equal value. The lines in Figure 5 show temperature variation in Fahrenheit for northeastern United States (U.S.) 3. Your task is to go online and find a thematic map of your choice and provide an explanation of what the map represents. Answer the two questions below and copy and paste a map in your document. Also, provide documentation of the website you obtained the map. In your online search, type in the words “thematic map” and a map topic of your interest. A. What is the title of your map? (1 point) B. What does the map demonstrate and how are the data illustrated? (3 points) C. Copy and paste your map to a word document and provide a proper citation under the map. If you cannot find an author of the map/website, you can use a line substitution convention for the author. (Map = 2 points) (Citations = 2 points) For example: __________. 2022. Landscape and Urbanism. Available: https://www.landscapeandurbanism.com/2015/07/09/topoview-for-historic-usgs-maps/. Accessed: June 01, 2023. For problem 3, upload your word document to the link titled, “ Question 3 write up – Lab 2 – submit here ” under the Map 2 assessment link in module 3. Once your instructor has graded your map, the points will be added to the lab 2 – Maps Assessment. Figure 4. Major Earthquake Locations in Hawaii .
