Determine the latitude and longitude of the MIT campus using a method of your own choice without using GPS or a map (or any web resources that tell you the latitude and longitude). Your submission should include:

• A discussion of your method and why you choose it.
• The data collected during your measurements.
• Calculation of the latitude and longitude.
• Your assessment of the accuracy of your values. An explanation of how you determined this accuracy should be included. (The assessment should be as quantitative as possible.)

Determine the radius of a circular green. There is a grass inner ring and a concrete outer ring. The radius of the outer edge of the concrete ring should be determined. In the center of the circle is a sprinkler head, use an indirect method (i.e., not by direct distance measurement) to determine the distance from the sprinkler to the outer concrete edge.

Use the EDM (Electronic Distance Measurement) to make the measurements of the radius of the circle. Students must reduce the results by the next class.

From the measurements made you are to determine:

• Estimates of the radius from the main tripod measurements.
• Estimates of the radius for each rod measurements. Plot the radius as a function of angle around the center of the circle.
• The distance from the sprinkler in the center of the circle to the center of the center of circle.
