What are Digital Terrain Models created for?

Digital Terrain Models (DTMs) are specifically created to represent the physical features and characteristics of a geographical landscape. They accurately display terrain elevation and contours, which is crucial for understanding the topography of a site, assessing drainage patterns, and planning for earthwork.

While manipulating and importing surveying points is an essential part of generating DTMs, the primary purpose of these models is to accurately represent the geographical landscape itself. This includes detailing elements like hills, valleys, slopes, and other surface features, which are vital in various fields such as environmental studies, civil engineering, and construction planning.

Thus, the correct response highlights the essence of DTMs as tools for providing an accurate representation of geographical landscapes, which is critical in decision-making and planning stages of construction projects.
