Lab 2 - Maps and Google Earth

Name Lab 2 Maps and Google Earth Required materials Pencil Ruler Topographic map of “Arthur Kill” Computer with Google Earth software loaded Use the following links to learn of how to interpret the information related to topographic maps: http://pubs.usgs.gov/gip/TopographicMapSymbols/topomapsymbols.pdf http://www.britannica.com/science/latitude http://pubs.usgs.gov/fs/2001/0077/report.pdf http://oklahomastationsci. org/images/MapMarginInfo1.pdf http://www.wiley.com/legacy/Australia/61_68737_Atlas8E_018-19.pdf ° In-class lab exercises Part 1 Topographic maps What are the contour intervals in the diagrams below? (Assume the scale is in feet)

Match the following contour maps with the descriptions. 180 170 160 150 600 550 1400 1000 150 100 50 A 100 200 B 600 400 200 C 200 100 D 200 100 E 200 100 F e

1 N ext, you will be working with the “Arthur Kill” topographic map quadrangle. What is the scale of the map, expressed as a ratio? How many inches represent 1 mile? How many feet are represented by 1 inch? What is the contour interval of the map? From which series is the map? When was the map made? When was it photo revised? What is the latitude of the northern boundary of the map? What is the latitude of the southern boundary of the map? ° What is the longitude of the eastern boundary of the map? What is the longitude of the western boundary of the map? Which maps border the Arthur Kill Quadrangle? North South East West Northeast Southeast Northwest Southwest Use the guide to UTM coordinates and the key to symbols on topographic maps that you downloaded during the pre-lab to help you answer the following questions. Using the information, you learned earlier about contour lines, find an example of each of the following features on the Arthur Kill map. Give the UTM coordinates of the feature you have found.

1 ° Part 2 Google Earth Open the Google Earth software on your computer. In the ‘search’ box type ‘Staten Island’. Zoom in and center the image, so that you can clearly see the whole island. For the next part of the exercise, you need Google Earth to display UTM coordinates, rather than lat/long. Select “Tools” then “Options”. In the dialog box, change the “Show lat/long” category to “Universal Transverse Mercator” and save the settings. Find the location of 571224 4486689 on Google Earth and mark it as point 1. What is the land-use of the surface at this location? Find the location of 570367 4490790 on your map and mark it as point 2. What is the land-use of the surface at this location? Using Google Earth to construct "Vertical Profiles" Easting Northing Point 1 571224 4486689 Point 2 570367 4490790 ° Select the “Placemark” tool, and label your first placemark “Point 1”. Type in the Easting and Northing then click OK. Repeat for point 2. Then use the ruler tool to draw a topographic profile. Select the “Ruler” tool, and click on the
