Unit 39 - The TIN Model
This unit introduces the Triangulated Irregular Network (TIN) model for representing a surface as an alternative to the regular raster of a digital elevation model (DEM). The TIN concept is described, and several alternative methods for creating a TIN—including point selection and triangulation—are presented. The unit concludes with sections considering storage of TINs and several algorithms on TINs
