b) 5 inches on the map is equivalent to how many miles on the ground? 2.64
c) one mile on the ground is equivalent to how many inches on the map? 30
d) 3 kilometers on the ground is equivalent to how many centimeters on the map? 1.25
7. What is the contour interval on your map? 20 Feet
8. What are the approximate geographic coordinates in both degrees/minutes/seconds and decimal degrees of:
a) the tip of the Santa Monica pier   34°N 118°30'W

b) The Upper Franklin Canyon Reservoir 34°7'10"N 118° 24' 35"W
9. What is the approximate elevation in both feet and meters of:

a) Greystone Mansion in Greystone Park  650ft, 198m

b) Woodlawn Cemetery 140ft, 43m

c) Crestwood Hills Park 600ft, 183m

10) What is the UTM zone of the map? 11
11) What are the UTM coordinates for the lower left corner of your map? -Skip-
12) How many square meters are contained within each cell (square) of the UTM gridlines? -Skip-
13) Obtain elevation measurements, from west to east along the UTM northing 3771000, where the eastings of the UTM grid intersect the northing. Create an elevation profile using these measurements in Excel (hint: create a line chart). Figure out how to label the elevation values to the two measurements on campus. -Skip-
14. What is the magnetic declination of the map? 14°
15. In which direction does water flow in the intermittent stream between the 405 freeway and Stone Canyon Reservoir? South

Week 1 Lab: 3 Maps

This map of Seattle from the turn of  last century, has a really interesting, almost aerial view- as one would have imagined the city looked from above.  It contains what would have been considered the most important locations at a time when tourism wasn't the major industry, but shipping was.  This one is located in files originating from the University of Washington and was created in 1891.  It shows the familiar grids of downtown before the advent of the Alaska Way Viaduct and the freeway system.  It's interesting to think about the similarities that still exist along with the obvious changes.

 

 In this fantastic topographic map of the moon, we get to see the low-points and high-points as they would be colored for any Terran location, which gives us an impression of what the moon would look like if it were a green planet, where it's oceans, if there were such things, would be located, and so also what those coast lines would potentially look like.  In addition to that, the craters add such interest to the landscape. This map comes from an online astronomy site, http://cseligman.com/text/moons/moonnear.htm, where maps of many other views of our moon are also available.

The above map of Nashville TN shows details of a Cholera outbreak, defining where the illness sprang up and illustrating quite handily the source of the water-born disease.  It also shows that the wells and still water were more contaminated, than the moving waters of the river and streams.  Maps like this are so incredibly useful- and this is an early example of finding the correlations between geography and public health.  This map is from a cholera specific website, http://www.nlm.nih.gov/exhibition/cholera/images.html, and was created in 1873.
