Overview of Mapping-Contouring System (PDF; 85 KB)
Workshop Description
Compare and contrast various methods of contouring, by hand or by computer, single surface or multi surface, nonintersecting or intersecting surfaces, faulted or nonfaulted. You will spend about half of your time contouring single surface, multi surface and faulted problems. You will learn new and helpful methods of hand contouring.
Who Should Attend
Exploration or production geologists, geophysicists, and engineers who want to:
Gain new insight into techniques of hand contouring
  How to get started on a new project
  Tools to help you quickly position 'geologic' contours
Be able to generate contour maps by hand
  Single surface
  Multi surface
  Intersecting surfaces
  Faulted surfaces
Learn the methods used by computers to generate contours
  Direct (Gridding)
  Indirect (Triangulation)
Learn how to assess the veracity of computer contoured maps
  Single surface
  Multi surface
