Geospatial Science is a discipline that focuses on using information technology to understand people, places, and processes of the earth. Spatial analysis of human and physically variables is fundamental to the discipline. Remote Sensing, Geographic Information Systems, and Global Positioning Systems technologies are commonly used as measurement, observation, and analysis tools for this (Radford University, 2014 AU44: The in-text citation "Radford University, 2014" is not in the reference list.

Abstract
The first human footprints dated more than 1.9 million years ago; the Homo erectus era, “upright man,” marks the beginning of man's socio-economic historical development. It culminated in the Bronze Age, Iron Age, Industrial Revolution, and currently the Information Age. The current era has allowed rapid global communications and networking to shape modern society. Individuals are able to transfer information freely, with instant access to knowledge that would have been difficult or impossible previously. This chapter elaborates upon GIS/remote sensing: the highest echelon in ICT. It compares and contrasts the four globally used GIS systems of GOES, the Geosynchronous Orbiting Environmental Satellite; LANDSAT; SPOT, Satellite Pour l'Observation de la Terre; and the WorldView. Their temporal resolution, spatial resolution, spectral resolution, radiometric resolution, and their DEM characteristics are reviewed. The human side of information reference services in the form of TEK is alluded to.
