Question

5 which technology is essential for gathering data about the earth’s surface in gis?

a. geo-referencing to align data

b. the art of cartography for manual maps

c. barometric sensors to measure air pressure changes

d. remote sensing from satellites and aircraft

Explanation:

To determine the essential technology for gathering Earth's surface data in GIS:

• Option a: Geo - referencing aligns data, not gather it. Eliminate.
• Option b: Cartography for manual maps is not for data gathering in GIS. Eliminate.
• Option c: Barometric sensors measure air pressure, not Earth's surface data. Eliminate.
• Option d: Remote sensing from satellites and aircraft is used to gather data about Earth's surface for GIS.

Answer:

d. Remote sensing from satellites and aircraft
