It offers a wealth of GIS data including RADARSAT, AVHRR, Aerial Photo Images, Census Data, Watershed Maps and many other data sets besides Landsat.
Instrumentation aboard various Earth observing and weather satellites such as Landsat, the Nimbus and more recent missions such as RADARSAT and UARS provided global measurements of various data for civil, research, and military purposes.
In addition to the SAR instrument, RADARSAT will include a scatterometer and two optical instruments. The scatterometer is a microwave sensor that collects data on wind speed and direction for a 600-km swath.
The control stations use precise RADAR equipment to determine each satellite's location, altitude, and velocity. The monitor stations also measure signals from the satellites which are incorporated into orbital models for each satellites.
Major advancements were made during World War II with the development of RADAR (Radio Amplified Detection and Ranging) and SONAR (SOund NAvigation and Ranging).

Remote Sensing and Image Processing ...
Most common mediums include satellite imaging, Global Positioning Systems, RADAR, SONAR, aerial photography, etc. Before the advent of photography, remote sensing was accomplished in such ways as information collection from air balloons.
remote sensing : Any of the technical disciplines for observing and measuring the Earth from a distance, including satellite imaging, Global Positioning Systems, RADAR, SONAR, aerial photography, etc.
The daily ice edge is constructed by NIC ice analysts using various imagery products with resolutions ranging from 100m to 12.6km. These imagery sources include but are not limited to RADARSAT, ENVISAT, DMSP OLS, AVHRR, and QUIKSCAT.
with the launching of a number of satellites called TIROS. Over time sensors became more sophisticated and some of them were used to monitor the Earth's surface for a number of applications outside of weather forecasting (LANDSAT, SPOT, and RADARSAT).
RADAR RAdio Detection And Ranging: an active remote sensing system that generates energy in the microwave wavelengths to map the earth's surface. It is not affected by weather or night.
