1 West Virginia University Department of Civil and Environmental Engineering Course Syllabus Course: CE Introduction to Geomatics Semester: Summer 2012 (6 weeks) May 21 June 29 Course Format And Credit hours: Prerequisite: Instructor: Each week 4 class periods, 100 minutes each 3 credit hours CE 210 or consent Dr. Darrell R. Dean, Jr., P.S. Office = TBD Darrell.Dean@mail.wvu.edu Schedule: MTWR: Location: Office Hours: Course Objectives: Expected Learning Outcomes: G3 ESB TBD or by appointment The objective of this course is to introduce students to the technologies used in the acquisition and processing of geospatial data for mapping, planning, designing, constructing, and managing the built and natural environments. Upon successful completion of this course, students are expected to demonstrate the ability to: Measurement Error Theory Describe two types of surveying measurement errors and three different categorical sources for these errors. List three properties of random errors and explain how random errors propagate or how they influence the end results of measured or calculated quantities. Describe the meaning of accuracy, precision, and resolution. Leveling Measurements Explain the theory of differential leveling by utilizing two equations and a labeled profile view showing a level, a leveling rod, the ground surface, the elevation datum, and other required variables. Conduct leveling operations by using a level to acquire backsights, foresights, intermediate foresights, and perform calculations to determine elevations and make the checks to verify and quantify the measurement results. 1

2 Calculate differences in elevation using backsights, foresights, elevations, and slope distances and slope angles. Describe the concept of stationing as used to define the location of points along a linear feature such as along a center line for profile leveling. Perform a simple level loop adjustment. Total Station Measurements Operate a total station to obtain angles-to-the right, vertical angles, slope distances, horizontal distances, and vertical distances. Describe the checks for horizontal angle measurements Explain the difference between a zenith angle and an angle of elevation or an angle of depression. Calculate horizontal distance given slope distance and a vertical angle. Describe how precision is expressed for distance measurements. List four units used in distance measurement and convert from one unit to the other. Traverse and Surveying Calculations Describe two traversing methods and three types of traverses. Given the bearing of one side of a traverse and any combination of interior angles, exterior angles, deflection angles or angles-to-the-right at the vertexes of a traverse, calculate the bearings and/or azimuths of all other sides of the traverse; or, given the bearings or azimuths of all sides of a traverse, calculate any of the above mentioned angles at each vertex. Perform traverse calculations for angle adjustment, bearing or azimuth, latitude, departure, linear error of closure, relative error of closure, compass-rule corrections, coordinates, area, and the inverse problem. Perform calculations to find the coordinates of line intersections using coordinate geometry (COGO) methods. Perform calculations for horizontal and vertical curves Perform earthwork volume calculations. Coordinate Systems, Projections, and Datums Describe the different coordinate systems used to represent points on the Earth s surface Name two common map projections used in engineering applications Perform calculations to convert geodetic (geographic) coordinates to state plane coordinates and vice versa (the inverse) Describe the components of the National Spatial Reference System and their significance to mapping and design data acquisition. Geospatial Data on the Web Identify the geometric entities used to represent geospatial data Describe the difference between a digital orthophoto quad and a topographic map in digital raster graphic format. Identify sources on the web for acquiring digital orthophoto quads, digital topographic maps, and other surveying and mapping related data. 2

3 Describe metadata. Use a GIS viewer to perform queries to locate geospatial data for a particular geographic location. GPS Measurements Describe the GPS system components Describe conceptually how GPS works Identify different types of GPS receivers Describe potential positional accuracy and factors affecting accuracy when using GPS Describe the different operational modes of using GPS receivers to acquire positions Operate a GPS receiver to acquire data and perform the processing necessary to determine positions for mapping and other engineering design requirements. Terrain Mapping/Modeling List and describe three technologies, other than GPS and total stations, for acquiring terrain data. Describe mass points, break lines, contour lines Use CADD software to create a 3D surface model suitable for creating topographic maps, profiles, and cross sections. Optional Texts: Elementary Surveying: An Introduction to Geomatics, 12 th Edition, by Ghilani and Wolf, Pearson Prentice Hall, 2008, New Jersey. Surveying Fundamentals and Practices, 6 th Edition, by Nathanson, Lanzafama, and Kissam, Pearson Prentice Hall, 2011, New Jersey. Grading: Assignments/Projects 80 % Midterm exam 10 % Portfolio or Exam 10 % 100 % Grade Assignment: A B C D 59 0 F Grading Policy: Late assignments are accepted at the discretion of the instructor. Assignments are due at the beginning of the period on the due date. Some lab assignments are due at the end of the lab. HW Assignments: Assignments/projects will be given for most units in the course. Point values will vary between 50 and 100 points. 3

4 Attendance Policy: Attendance is not counted in the grading system. However, attendance is recommended and encouraged. WVU recognizes the diversity of students, many of whom must be absent from class to participate in religious observances. Students must notify their instructors by the end of the third class meeting regarding religious observances that will affect their attendance. Further, students must abide by the attendance policy of their instructors as stated on their syllabi. Faculty will make reasonable accommodation for tests or field trips that a student misses as a result of a religious observance. Social Justice Statement: West Virginia is committed to social justice. I concur with that commitment and expect to maintain a positive learning environment based upon open communication, mutual respect, and nondiscrimination. Our University does not discriminate on the basis of race, sex, age, disability, veteran status, religion, sexual orientation, color or national origin. Any suggestions as to how to further such a positive and open environment in this class will be appreciated and given serious consideration. If you are a person with a disability and anticipate needing any type of 1accommodation in order to participate in this class. Please advise me and make appropriate arrangement with Disability Services ( ). Academic Integrity/ Honesty Policy: Calculator: Supplies: West Virginia University expects that every member of its academic community shares the historic and traditional commitment to honesty, integrity, and the search for truth. Students and faculty should act to prevent opportunities for academic dishonesty to occur, and act in such a manner to discourage any type of academic dishonesty. Academic dishonesty includes plagiarism; cheating and dishonest practices in connection with examinations, papers, and projects; and forgery, misrepresentation, and fraud. Complete policy statements and definitions on academic integrity/dishonesty can be accessed at: Bring a scientific calculator to each class period. You will need a file storage device to hold files for your computer mapping projects. A 4-inch diameter, circular protractor and engineer s scale are beneficial. 4
