Geographic Information Systems: Revolutionizing the World of Maps

What is the most significant technological development of the late 20th century in the field of geography?

a) Geocoded data
b) Geographic Information Systems (GIS)
c) Spatial grids

Answer:

The most significant technological development of the late 20th century in the field of geography is Geographic Information Systems (GIS).

Geographic Information Systems (GIS) have revolutionized the world of maps and spatial data analysis. These systems allow geographers, planners, and analysts to capture, store, manipulate, and analyze geospatial data efficiently.

By integrating hardware and software, GIS applications can accept data input and display it as two- or three-dimensional maps and other diagrammatic formats. This technology plays a crucial role in various fields, including urban planning, natural resource management, disaster response, and many more.

The ability of GIS to overlay different maps, combine spatial grids, and perform spatial analysis has made it an indispensable tool for geographers and other professionals working with geographical data.

Overall, Geographic Information Systems have opened up new possibilities and insights in the world of geography, shaping the way we visualize and analyze spatial information.
