Why go for 3D geospatial data from satellite sensors?

from Geospatial World

Important components of creating a GIS infrastructure that goes beyond two-dimensional space are real 3D vector data, digital terrain models, and information modeling of construction. The creation of three-dimensional GIS was made possible by integrating GIS methods and technologies, photogrammetry and remote sensing data. With the advent of digital photogrammetry, stereo images have become the main source of obtaining three-dimensional geospatial data. more
