Satellites |
Short revisit time, produced auxiliary records, gave free
of cost information besides data of unreachable places |
Low signal to
noise proportion, demand for geometric as well as atmospheric
amendments, atmospheric absorption affecting with spectral
quantities |
Airborne |
Extraordinary spatial resolution, gave data of unreachable
places, tools available in the range of (1000–2500 nm) |
Extraordinary
working complication, expensive, demand for meteorological environment
for remote sensing usage, official limitations for flight |
Unmanned Aerial Systems (UASs) |
Extraordinary spatial resolution,
designing of flight strategy by taking weather situations into
consideration |
Restricted payloads, restricted flight period, demand
for geometric as well as atmospheric amendments |
