Site engineering of landscape architects: outline, form, interpolation and slope

A clear understanding of what the contour represents is the basis of the grading design process. Technically speaking, a contour line is an imaginary line that connects all contour points above or below a fixed reference plane or datum. The datum can be average sea level or a locally established datum. Contours are graphic representations of contours on a plan or map. In order to make wise design decisions and accurately execute construction drawings, landscape architects need terrain data for all site development projects. This course discusses the concept of contour lines and describes the baseline of common contour line features. This course expands on these concepts through explanations of interpolation and slope formulas and examples of their applications. This course also introduces the basic mathematical equations related to drawing and manipulating contour lines. Access the course preview.
