Lab Write-up for Group Purple

Introduction

Our task was use three different methods to find the Latitude and Longitude of the Greenwich Theater. We were also tasked to find the elevation and distance to the Prime Meridian using two different methods and what was due south and North of the location. to find the various pieces of information we used the following methods

• Latitude
  • Google Earth
  • Reasonable Guess
    • Using a picture taken off Google Earth with two known degrees of latitude, then estimating where our location lies between them
  • GPS

• Longitude
  • Google Earth
  • Reasonable Guess
    • Figure out the distance to the PM, convert the linear measurement to degrees longitude, then add or subtract that from the 0 degrees (The PM)
  • GPS

• Elevation
  • GPS
  • Google Earth

• Distance to Prime Meridian
  • Counted the steps between the site and the PM, then figured out how many steps were in 100 feet, and used that to figure out the distance to the site.
  • GPS track feature

• Due South
  • Compass

• Due North
  • Compass

The Greenwich Theater was located several hundred meters from the Thames and had its back to the Royal Naval College. While the theater itself is fairly large, we were only concerned with the entrance which was a small awning overlooking a fairly quiet street. The Rose and Crown Pub was next door, which happened to be due North of the entrance. The Fan Museum was due South of our location.
