It culminated to Bronze Age, Iron Age, Industrial Revolution and currently 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/ impossible previously. This chapter elaborates upon GIS/Remote Sensing; the highest echelon in ICT world. 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 (Figure 6 – WorldView3); spectral resolution (Figure7 Landsat8); radiometric resolution (Figure8 WorldView3) and their DEM characteristics (Figure9 SPOT DEM) are reviewed. The human side of information reference services in the form of TEK is alluded to.
