Lab 2: USGS Topographic Maps

1. Beverly Hills Quadrangle
2. The adjacent quadrangles are Canoga Park, Van Nuys, Burbank, Topanga, Hollywood, Venice and Inglewood.
3. The quadrangle was first compiled in 1966.
4. There are three sets of datum used to create the map. For horizontal datum, the North American Datum of 1927 was used; this was later revised using North American Datum of 1983.  Finally, contour line datum were taken from the National Geodetic Vertical Datum of 1929.
5. The scale of the map is 1:24000. This ratio indicates that one unit shown on the map are equivalent to 24,000 of the same units in the real world. This scale is typical of USGS quadrangles, which include 7.5 minutes of longitude and latitude.
6. a. 5 centimeters on the map is equivalent to 1200 meters on the ground.
    b. 5 inches on the map is equivalent to 1.89 miles on the ground.
    c. 1 mile on the ground is equivalent to 2.64 inches on the map
    d. 3 kilometers on the ground is equivalent to 12.5 centimeters on the map.
7. The contour interval of the map is 20 ft.
