Which term is often used to describe a perspective view of a terrain model?

The term that is often used to describe a perspective view of a terrain model is "Pseudo-3D." This term refers to visual representations that create the illusion of three-dimensionality on a two-dimensional surface. In the context of geographic information systems, pseudo-3D visuals often employ techniques such as shading, contouring, and perspective rendering to help users perceive depth and elevation in terrain models, making it easier to interpret spatial relationships.

While "2D View" refers to a flat representation of spatial data without any indication of depth, "3D Projection" typically involves a more technical representation of three-dimensional structures, which may not necessarily provide a perspective view that appears natural or intuitive. "Virtual Terrain" may refer to interactively rendered landscapes in a virtual environment but does not specifically denote the perspective aspect inherent in pseudo-3D displays. Therefore, when discussing perspective views that enhance the visual understanding of terrain, "Pseudo-3D" is the correct term to describe such an effect.
