SUR 3501 : SPATIAL MEASUREMENT SYSTEMS

SPRING 2007

PROJECTS

Project 1: Distance Measurement:

Measure a set distance 20 times using (i) a tape (ii) a total station (iii) pacing, and express the quality of the results in various forms

College Football Rankings – analysis of conference strength

Project 2: EDM Calibration

Calibrate an EDM on an arbitrary baseline and determine the error constant and ppm error.

A. [Distance Lab Report for Projects 1 and 2]

 

Project 3:  GPS –Point Positioning

Determine the coordinate precision and accuracy for different GPS receivers (without differential correction)

Note Corrections to MSE and RMSPE in Project 3 document (2/13/07)

MSEX = S [(xi – ‘true value’)2] / n       RMSPE = SQRT (MSEX 2 +  MSEY2)

(Please use these three receivers for Project 3; you may use the above data or the data that you collected with any of these receivers)

Project 4:  GPS – Assess quality of OPUS solutions

Process GPS observations through OPUS and assess quality

Leica Observation at Natasha (Damon) on Share Folder at: \\ad.ufl.edu\ifas\SFRC\Private\Geomatics\SHARE\SUR 3501

You will need to convert these to RINEX within GeoOffice before sending to OPUS

Project 5: GPS – Assess quality of Differentially Corrected Observations

Compute differentially corrected coordinates for a point relative to three different sets of CORS (SkiPro)

Project 7: Monitoring Survey of Black Hall

a) Field and Office demonstration of Riegl Scanner (Ted Knaak)

Assume Azimuth 1-5 = 340000’00” and X1=100.000  Y1=500.000

 

b) Leveling (Group 2) … need heights by Monday MAR 5 latest

ท        Group 2 1st Level Loop

ท        Group 6 level observation (includes BaseS, BaseN, 6, 7)

ท        Field Sketch – level loop

ท        Final Level Computations

c) TS Survey of 7 ground control points (Groups 1 and 7) … need XYZ cords by Monday MAR 5 latest

ุ      Other Obs are on Share drive (contact John Perry if questions on this)

ุ     Adjusted Coords A (April4) …. Use these for wall points

ุ      Pairing for Computation of Az/Az intersections

ุ      Polars/Inverses Examples in Excel (incl. DMS-DDD and DDD-DMS converter)

e) GPS of 2 Stable Points (Group 6) …. Second base point (BaseN) has been installed – go ahead with GPS survey (1 hour observations – use your own base station over a known point (e.g. Roof) as well as GNV CORS. IN 2nd session collect for 30 mins for the vector between BaseS and BaseN

 

f)  Comparison of scanner and survey control coordinates and analysis of wall points

ท        Control Point Coords used for Scanner
