How does remote sensing help in environmental studies?

What is remote sensing and how is it used in environmental studies?

Remote sensing is the acquisition of information about an object or area from a distance, typically using satellites or aircraft. In environmental studies, it's used to monitor changes in land use, vegetation, and climate.

Can you give examples of how remote sensing has been applied in real-world environmental issues?

Sure! Remote sensing has been used to track deforestation in the Amazon, monitor water quality in lakes, and assess the impact of urbanization on local ecosystems.

What are the benefits of using remote sensing over traditional methods?

Remote sensing allows for large-scale data collection over vast areas, providing timely and accurate information that can be difficult to obtain through ground surveys alone.

Are there any limitations to remote sensing in environmental studies?

Yes, limitations include issues with data resolution, atmospheric interference, and the need for ground truthing to validate the data collected.
