Various remote sensing technologies are presently used to derive land surface and sub surface information. Each individual system (sensor) has its own advantages and disadvantages. The new airborne interferometric RADAR system OrbiSAR-1, developed, manufactured and operated by Orbisat da Amazonia's Remote Sensing Division, created a new way of automated mapping. Due to the use of microwaves as sending and receiving impulses of the sensor, the system is independent of day light and can therefore even map at night. As the microwaves are not influenced by the presence of clouds, the system can even map in bad weather situations, like rain or closed cloud coverage.
