Lab 2: Holy Pigeon P$#! Batman, it's Penelope Poison!

Green: Krystnell, Johanna, Spencer, McKayla, Gillian

Problem Description and Approach

For this lab, Dr. Obsfucation sent out eleven photographs of various bodies of water around central London. He informed us that Penelope Poison was threatening to release toxic substances at each location; he asked the Green Team to find each location using the photographs and take several readings at each location: longitude, latitude, elevation, wind direction, wind speed, water temperature, and air temperature. More importantly, for every reading it was necessary that we take three readings in order to make an accurate measurement.

Our initial approach dealt with using the geo-coding of each photograph to identify the longitude and latitude and then map out the locations. The photos were downloaded and imported into iPhoto, where the "Places" application created a map of the locations. With a time element involved, we decided to head towards Regents Park first, where two photographs were taken, and make our way back Trafalgar Square, via Hyde Park and then Green Park / St. James Park. The methodology for the collection of necessary data is explained below.

Data Collection

In order to measure the latitude, longitude, and elevation of each site, we took three separate readings using a yellow Etrex GPS unit. At each location, we turned on the unit, waited for it to locate the satellites, and recorded the first set of readings. Then we moved the GPS unit away from the location and back to cause the GPS to take a new reading from the satellites. We recorded this second set of raw data and then moved the GPS a second time to for a final set of readings.

In order to determine wind direction, three group members took turns using a cigarette lighter at the location to determine the direction of the breeze, faced in that direction, and then took an angle reading using the compass. All three readings were recorded. In order to determine wind speed, different group members used the Beaufort scale to estimate a speed without consulting each other, and recorded their decision.

To determine water temperature, we pointed the Mini Infared Thermometer Fluke-62 at the body of water pictured in each photograph, recorded the temperature reading, and repeated this process two more times to come up with three readings. To determine the temperature of the air, we pointed the infared thermometer at the sky, pressed the button to take a reading, and repeated this two more times to produce three readings.

Appendix C: Who Did What

Spencer ~ During the lab I was responsible for recording the data as well as providing one of the three readings for both wind direction and wind speed. Because I downloaded the pictures onto my computer before the lab, and was able to identify their locations with this, I wrote the "Problem Description and Approach". After McKayla calculated the measurements and entered the raw data onto the wiki, I edited it with the proper notations. I also created the table with all of our measurements.

Johanna ~ During the lab I used the GPS unit to take readings for latitude, longitude, and elevation, as well as helping determine wind direction with the lighter. I wrote the data collection section of the lab write-up.
