Which of the following is NOT an example of 3D GIS data?

Raster data is primarily a 2D representation, consisting of a grid of cells where each cell has a value representing the characteristics of that area. While it can contain elevation values to represent terrain surfaces, it does not inherently provide the three-dimensional relationships or spatial features that are typical of 3D GIS data.

In contrast, point cloud data, lines and polygons with Z values, and multipatch data are all specifically structured to convey three-dimensional information. Point clouds represent 3D points in space, often derived from LIDAR scans or similar technologies that capture the physical structure of environments in detail. Lines and polygons with Z values represent structures that have both horizontal and vertical components, essential for 3D visualization. Multipatch formats are used to represent complex 3D shapes and surfaces, allowing for the detailed modeling of objects in three dimensions.

Understanding the differences in data formats is crucial for utilizing GIS effectively, as each type of data serves specific needs and applications in the realm of spatial analysis and environmental modeling.
