construction/ Civil Engineering: AutoCADD drawing (Elevation and contour lines using the method of interpolation) This is the assignment description. You only need to do the drawing section on the back see "Results" go to this link to find (collected data from GPS) https://www.sendspace.com/file/psxisn Florida Institute of Technology . CVE 2080 Construction Measurements Lab Fall 2015 Page1 WELAB #6: TOPOGRAPHIC SURVEY USING THE GPS DEVICE BOBJECTIVES 1. Gain an understanding of using the GPS device. 2. Take elevation readings using the GPS device. 3. Draw a contour map based on the elevations obtained. TEXTBOOK REFERENCES. Section 17.5 - Contours on page 471 Section 18.9 - Contour Interval on page 514 Section 18.10 - Plotting Contours on page 514 JNTRODUCTION Using the GPS device and other methods used in previous labs, determine elevations at points within a given transect. The readings shall be taken as a grid with no reading less than 15 feet from the previous reading. After the elevations of the transect are known a contour map of the transect shall be developed and compared to the results of previous labs. EQUIPMENT NEEDED 1. GPS Rover 2. Scepter PDA 3. Rod 4. Rod level 5. 50-meter tape PROCEDURE A five-sided closed traverse has been staked off by the Olin Physical Science Building. No Benchmark is provided for the purposes of this lab. Establish a grid using the 50-meter tape and marker pins by using the following procedure. The grid should enclose the entire traverse. It should consist of points no further than 15 feet from the previous point. 1. ’Place the battery in the GPS rover. 2. Turn on both the PDA and the GPS rover. Ensure that the GPS states that it is in ‘fTSM Rover” mode. 3. Ensure that the PDA is connected to the T-Mobile data service plan. 4. Open the SuerE program in the start menu of the PDA. 5. Create a new folder with your group name and a new file for your group to begin taking the readings. 6. Connect the GPS Rover to the PDA by entering the equipment menu and selecting rover. Then click the check mark to initialize the connection. 7. Choose the survey option and begin to take reading ensuring that hsig and vsig are within the allowable tolerances. These procedures are general for the use of the GPS. Procedures included in report should be much more detailed.
