4.2 Satellite Applications in Cartography

Satellites have redefined the standards of cartography by providing high-resolution, up-to-date imageryLanguage appealing to the senses (sight, sound, smell, touch, taste). that support topographic mapping with digital elevation models that use satellite data to present detailed terrain. They also support thematic mapping, displaying vegetation cover, urban sprawl, and natural resourcesThe inputs used to produce goods and services, including the factors of production. (Denègre, 2013).

Application of Satellites

The integration of satellite data into Geographic Information Systems (GIS) has enabled comprehensive spatial analysis. By combining multiple data layers, GIS platforms support decision-making in fields such as urban planningThe process of preparing ideas, structure, and possible answers before delivering the spoken presentation., agriculture, and disaster management.

The Ordnance Survey (UK) employs satellite-derived data to maintain accurate and dynamic maps, ensuring reliable geographic information for governmentThe public authority that provides services, collects taxes, sets laws and regulations, and helps manage the economy. and public use (Ridley, 1997).
