2. GPS Surveying GPS -- how it works GPS -- Garmin 12

3. The Garmin 12 GPS Change windows Confirm Get back to a point Use to scroll and for keying TURN ON

5. Trilateration and a 4 th for timing

6. First page up…. 4 important pieces of data The satillite It’s signal Nav Error

7. Once you have a fix Where you are Your elevation (flaky) Are you late? Are you moving?

8. Getting back to where you started Follow the arrow Monitor Speed Check Distance Hit GOTO Pick a Waypoint

9. Non-corrected 5-30 m Beacon-corrected 1 m Radio-corrected cms Post-processed dm to m GPS Accuracy

10. Differential GPS for precision surveying of river terraces and alluvial fans

11. Crash Course in Surveying With an Auto Level:

12. :( (: 1 First thing first: Gotta level the it

13. CENTER LINE - ELEVATION  BOTTOM = DISTANCE TOP = DISTANCE 1

14. 1 The Auto Level: The Instrument And Tripod The Stadia Rod Or Surveyor’s Staff = l (m) * 100 (m)

15. How to read the Stadia Rod: 11 meters on the dot 10.8 meters on the dot Each Black Rectangle = 1 cm Same for Each white one So what’s this height? 10.66 meters

16. What you’ll see through the eyepiece: Stadia Lines Height = 10.85 m Top Stadia = 10.91 m Bottom Stadia = 10.79 m To Get Distance Away: 1)(Top - Bottom Stadia) = 0.12 m 2) Multiply difference by 100: Distance = 12 meters

17. 1 For your X-section, be sure to get any Major changes in slope Distance Height (X, Y)

18. How to collect the data: NOTE: When shooting features off your line, you will also need a bearing

20. ?

21. Side-Scan LiDAR: GeoArcheology

23. “Project North” is at the white house, And that is BM1 Figure out appropriate scale for x: 1 box = 1 meter? 10 meters? You want your entire survey to fit! Same scale as x-axis BM 1 BM 2 BM 3 BM 4 PN
