The highest generally available resolution is less than 1 m for panchromatic
remote sensing data.
9. When was remote sensing first used?
Most people consider the use of the telescope in the 17th century to be the
first use of remote sensing.
10. How is remote sensing data usually stored?
Remote sensing data is usually stored on computer using a raster format.
