Important Announcement! - Since this is a one hour course the University has decreed that the Final Exam be given on the last day of class - Tuesday Dec. 6th. Your Final Exam is to complete the drawing of the campus above and below ground as described under key announcements and to report to Diana and fill out a course evaluation (Diana will determine compliance on this one). It is expected that one problem on the final map is that some people will believe that they should not put their work in until 11:59PM on Dec. 6th. This will mean that everyone else cannot include the work until it is done. To deal with this problem we will check everyones files on the morning of Dec. 7th to see if each team has prepared the files they are responsible for. If not it will reflect in the grade. Then by the close of the Departmental business office on Dec. 7th everyone will need to turn in an electronic version of their completed file including the work of others.

Key Announcements
For your final survey project you will take your own traverse showing all the points you occupied on the surface as measured by regular surveying, GPS, and Brunton Traverse. You will also add all the building corners you measured with lines connecting the corners. You then will take the building corners and lines from all other teams and add them to your own drawing. (Note that you do not have to put in the points that other people occupied and surveyed again with GPS and Brunton - the requirement to include the points your instruments occupied on the surface pertains only to your own work). The result of this work should be the footprints of Engineering, Agriculture, Neckers, two Thompson Point dorms, and the Communications building.
Now add the underground tunnel system. For the portion of the tunnels you surveyed plot the centerline of your survey and using the offsets you measured draw in the walls of the tunnels. Remember to include the locations of grates and manhole covers. Add the tunnel work of other teams to your drawing only for other teams you need only show the centerline of the survey and the locations of manholes and grates.
You may submit your final project as a team (ie - you and your partner need only submit one drawing instead of two). Your drawing should be in MineSight and the project should be saved to a disk or thumb drive (ie- you will submit your drawing electronically - not as paper).
The diagram above reflects the various tunnel surveying assignments. Team 2 (Mike and Matt) shot in the coordinates for points 1 and 2. The coordinates are
#1 E 2,570,455 N 381,970.03 El 454.51
#2 E 2,570,455 N 381,979.03 El 454.96
Obviously the backsight line for an instrument under point 2 is azimuth 180.
This information is needed by teams #3 (Bruce and Sean) and #5 (Anthony and Nick C)
By Thursday team #3 is to have the coordinates of points 3, 4, 5, and 6 computed. This information is needed by team #1 (Larry and Cameron) and team #4 (Nick and Scott).
#3 E 2,569,901 N 381,994.38 El 442.72
#4 E 2,569,889.03 N 381,993.25 El 442.5
(assume points 3 and 4 indicate a foresight azimuth of 274)
#5 E 2,569,918 N 382,325.59 El 445.6
#6 E 2,569,917.68 N 382,332.82 El 445.4
By Tuesday (Nov. 22) Team #4 (Nick and Scott) are to provide the coordinates points 7 and 8. These points are needed by team #7 (Corbin and Donavan). The coordinates will be added when they are available.
#7 E 2,569,844 N 383,160.07 El 446.61
#8 E 2,569,842 N 383,162.14 El 441.74
By Tuesday (Nov. 22) Team #1 (Larry and Cameron) are to provide the coordinates for points 9 and 10. These points are needed by team #6 (Idris and Brandon). The coordinates will be added when they are available.
#9 E 2,569,182 N 381,525.88 El 448.74
#10 E 2,569,180 N 381,531.87 El 448.74
Note! These coordinates have been updated for a previous error.
When you do your underground surveying you will take your first shot using two known points - the point you are under and your backsight. The following spreadsheet can be used for this first shot underground
Traverse Survey Book 2011 with 2 known points.xls
For one group they had their foresight direction shot in by another team rather than their backsight points. For this team the following special purpose spreadsheet will be needed for their initial shot.

You will be required to produce maps of portions of the SIU campus from your surveying work. Your spreadsheets calculating your point coordinates and the maps you draw are to be stored on the S drive of the Mining Lab computers. Each of you have a subdirectory on the S drive. Everyone can see your work, but only you can change it. You will have to "map" your access to the S drive on each computer you work with. The PDF file below shows how this is to be done.
