What are the differences between ground based research methods and remote sensing research methods?

Answer 1

In remote sensing, aircraft or satellites provide the platforms for sensing applications. The primary difference is that in the remote sensing methods, a lot more area can becovered in a very short period of time than with ground-based methods. There are details that cannot be resolved by the remote methods that can be determined on the ground, but there are trade offs with the two methods of investigation. More and more sophisticated way of "looking" at the ground from remote platforms continue to be developed. The location of South American temples hidden in the jungle is just one example of the capability of the remote platform.

Answer 2

Ground-based research methods involve collecting data on-site through direct observation, sampling, and measurement. Remote sensing research methods use satellite or aerial sensors to collect data from a distance without direct physical contact. Ground-based methods provide detailed and accurate information but are limited in spatial coverage, while remote sensing methods cover larger areas but may have lower spatial resolution.
