How accurate is satellite imagery?

How accurate is satellite imagery for mapping purposes?

Satellite imagery can be highly accurate, often within a few meters, depending on the satellite and its sensors.

What factors affect the accuracy of satellite images?

Factors include the resolution of the satellite, atmospheric conditions, and the processing techniques used.

Can satellite imagery be used for real-time monitoring?

Yes, some satellites provide near real-time imagery, which is useful for monitoring changes like deforestation or urban development.

How do different satellites compare in terms of accuracy?

Different satellites have varying resolutions and capabilities; for example, commercial satellites often provide higher resolution than government ones.

Are there any limitations to using satellite imagery?

Yes, limitations include cloud cover, resolution constraints, and the need for ground truth data to validate accuracy.
