  1. Evergreen Valley College Civil Engineering Technology Program (Surveying) “Traditional Surveying Classes”

  2. Introduction • Gwen Gee, PLS • Adjunct Professor at EVC • ENGR 60 and 61 (Plane Surveying) • CET 141 (Boundary Control & Legal Principles) • County Surveyor for Santa Clara County, California • Graduate of California State University, Fresno • Surveying & Photogrammetry – School of Engineering (Geomatics Engineering)

  3. Traditional Surveying Classes • Purpose • It’s the “Why” in “Why we do it that way” • (Procedures) • It’s the “Understanding” in “Understanding what pressing that button does” • (Theories)

  4. Technology “Fall Out” • “Surveyors” have become “button pushers” • Instruments more advanced • Robotics, on-board computer etc. • Software is easier to use • “Just press a button…” • “It does it for you…” • Lack the knowledge of what happens when pressing buttons • Don’t really know what “pressing the button” really does • Going back to the basics…..

  5. The Traditional Classes • Core Subjects • Plane Surveying (Engr 60, 61) • Land Boundaries (CET 141) • Specialized Areas • Photogrammetry • Construction • Astronomy • GPS • Mapping • GIS

  6. Core Subjects • Plane Surveying • Typically covered in two semesters • Lecture • Traversing, leveling, horizontal and vertical curves, control surveys, etc. • Lab • Hands-on experience using surveying instruments • Computation • Take field notes, record data, set up the field process, reduce data • Field measurements • Work in groups, communicate with lab members Good math and communication skills!

  7. Core Subjects (cont.) • Land Boundaries • Boundary Control • Property surveys, process used to determine land boundaries • Exposed to legal descriptions of properties and their conflicts • Hierarchy of boundary control principles • Legal Principles • Laws that define land boundaries • Laws that govern the practice of surveying (State & Federal laws) Good reading comprehension!

  8. Specialized Areas • Photogrammetry • Aerial photographs • Topographic maps • Infrared, remote sensing • Digital and computerized trends • LIDAR – laser scanning Uses computer skills, physics, and math to understand how it works! • Construction Surveys • Interpreting construction plans • Perform calculations for • Layout (staking) • Checks (control) Involves complex calculations and good math skills!

  9. Specialized Areas (cont.) • GPS – Global Positioning System • Satellites • Survey grade GPS equipment • Easy to use • Becoming affordable Understanding theories requires higher math and science ! (statistics, physics) • Astronomy • Using the stars constellation for positioning • Latitude, longitude, azimuth • Doesn’t need batteries like GPS • Can use survey instruments that don’t require electronics Uses higher math for spherical trigonometric computation!

  10. Specialized Areas (cont.) • Mapping • Topographic maps (used for designing) • Boundary maps, plats, i.e. Subdivision Maps and Parcel Maps (used in land development) • Construction plans • Survey control mapping • As-Built drawings Uses CAD skills and math related to survey computations! • GIS – Geographical Information System • Graphical database • Base layer involves theories of control surveys and map projections • Has multiple uses and users Involves complex computer skills and organizational skills!

  11. Traditional Survey Classes Benefits • An understanding of how it all works (so when “pressing” a button….) • Leads to being able to make it work better • Allows you to know when you get a wrong answer • Allows you to know why you get these answers • Enables you to explain your results with authority

  12. Traditional Surveying Classes • Provides a solid foundation of surveying knowledge • Enables students to branch off into related subjects • Avoid having to unlearn incorrect procedures • Able to analyze and solve problems • Interactive learning environment

  13. How do many surveyors learn now? • Self taught from • books • OTJ = On The Job • co-workers (“that’s the way it’s always been done” syndrome) • Union apprenticeship (construction) • Company procedures (manuals) • Surveying Classes
