Summary
By introducing the model used throughout the remainder of the work, this section has also attempted to clarify for the reader the impact of various design choices in the model and to highlight uncertainties and gaps in the data set from which the model was produced. While the choices made during individual 3D monument and terrain construction are discussed more thoroughly in Sections 6 and 8, more important to the use of the model for analysis is this overall framework, as it structures the types of questions that can be asked, the scale at which analysis can take place, and the limitations of the model in general.
