GY301 Geomorphology Lab 5 Total Station Project Introduction For this lab you will use the Total Station to survey a topographic map of the campus area corresponding to the area outlined in Figure 5 Your project can begin by choosing any convenient location in Figure 5 STO1 ST16 however make sure that you can resection to 3 mirror targets established on benchmarks when setting up your instrument If you can t resection to 3 target benchmarks backsight by coordinate to a benchmark after setting up the instrument on another benchmark Shoot back to that benchmark or another visible benchmark to verify accuracy The mapping will use the UTM NAD27 zone 16 coordinate system therefore you must make sure that your total station instrument is set to use meters You can download a list of the benchmark UTM coordinates and elevations at http www usouthal edu geography allison GY 301 TotalStationLabBenchmarks xls Use include the following on the ArcGIS contour final map 1 Scale of 1 2 000 2 Contour Interval of 0 2m labeled index contours every 1 0m 3 Post map of data points red crosses 4 Title Total Station Project 5 Name and date due in lower right corner 6 The corners of the Library LSCB LSCB Biology Lecture and new Administration Building Meisler should be identified as points on the survey In ArcGIS draw polygons that connect these points 7 Survey the trees 1 9 that are the white course used in the pa
