Open the below file in ArcGIS. Add a basemap or layer with worldwide data. Use this form to answer questions about the data. You will win an entry in the prize drawing for every correct answer.
Use the following list of coordinates and projection information to find the target points and perform the indicated actions to obtain photos or tokens that you can exchange to enter the prize drawings at the Friday closing event.
Take a photograph of the view to the east while standing on this iconic symbol:
38 degrees, 38 minutes, 52.8 seconds N; 90 deg, 18 min, 17.5 sec W (Datum = WGS 1984)
Snap a photo of yourself in front of the building that lies to the west of these coordinates:
873819 Easting 1025182 Northing (NAD 1983 StatePlane Missouri East FIPS 2401)
There is a nice view to the north of this point, bring us a photo, get an entry into the prize drawing:
873320 Easting 1024610 Northing (NAD 1983 StatePlane Missouri East FIPS 2401)
Datum is important, see what you find at this point...and don't forget to snap a photo:
552870 Easting 1023480 Northing (NAD 1927 StatePlane Missouri East FIPS 2401)
Maps allow us to visually locate features but many of them also enable us to identify exact locations based on a pair of coordinates. Other devices such as GPS or cell phones allow you to use satellites or cell tower triangulation to obtain a set of coordinates describing your current position with varying levels of accuracy. These coordinates can be given in a number of different formats. Geographic Coordinate Systems utilize various spherical datums to describe the irregular shape of the earth and latitude and longitude values to exactly reference a particular spot on the planet. Projected Coordinate Systems are used to convert spherical coordinates into a system that can be easily displayed on a flat screen or map. Sometimes converting between these systems is required to obtain coordinate pairs that can be plotted on a map for navigation.
Geocaching involves using a GPS unit to navigate to a hidden "cache" that can include a written log or some kind of "treasure" for those skilled enough to find the locations. Today's challenge is similar to geocaching and involves using coordinate pairs (and sometimes clues) to find locations on the Danforth campus. See if you can navigate to the indicated targets to take photos or obtain tokens that you can exchange for entries into the prize drawings at the closing event on Friday.
