Remote sensing satellite and data overview

overview table
For a summary of major remote sensing satellite systems see the overview table.
A variety of remote sensing systems exist, for which the specification is distributed among a variety of websites from data providers, satellite operators and manufacturers.


RADARSAT International
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.


Polarimetry is used in remote sensing applications, such as planetary science, astronomy, and weather radar.

Digital elevation model

Mappers may prepare digital elevation models in a number of ways, but they frequently use remote sensing rather than direct survey data.

Ruth DeFries

Ruth DeFries (born 1957) is an environmental geographer who specializes in the use of remote sensing to study Earth's habitability under the influence of human activities, such as deforestation, that influence regulating biophysical and biogeochemical processes.

Geometric remote sensing includes position and deformation imaging using InSAR, LIDAR, etc.
Interferometric synthetic aperture radar, abbreviated InSAR (or deprecated IfSAR), is a radar technique used in geodesy and remote sensing.


photographerphotographicstill photography
Examples of passive remote sensors include film photography, infrared, charge-coupled devices, and radiometers.
Uses of full spectrum photography are for fine art photography, geology, forensics and law enforcement.

Topographic map

Digital elevation models (DEM) were also compiled, initially from topographic maps and stereographic interpretation of aerial photographs and then from satellite photography and radar data.


In airborne and space-based remote sensing such photon counters are used at the upper reaches of the electromagnetic spectrum such as the X-ray to far ultraviolet.

Inverse problem

inverse problemsinverse theoryinversion
Generally speaking, remote sensing works on the principle of the inverse problem: while the object or phenomenon of interest (the state) may not be directly measured, there exists some other variable that can be detected and measured (the observation) which may be related to the object of interest through a calculation.
They have wide application in system identification, optics, radar, acoustics, communication theory, signal processing, medical imaging, computer vision, geophysics, oceanography, astronomy, remote sensing, natural language processing, machine learning, nondestructive testing, and many other fields.


The design later became known as the LM-900 satellite bus and was optimized to carry remote sensing payloads.

Other uses include different areas of the earth sciences such as natural resource management, agricultural fields such as land usage and conservation, and national security and overhead, ground-based and stand-off collection on border areas.

PCI Geomatica

GeomaticaPCI Geomatics
PCI Geomatica is a remote sensing desktop software package for processing earth observation data, designed by PCI Geomatics.


It represents a key technology as part of the aerospace industry and bears increasing economic relevance – new sensors e.g. TerraSAR-X and RapidEye are developed constantly and the demand for skilled labour is increasing steadily.
1996: The RapidEye business concept was designed by Kayser-Threde GmbH, based on a call for ideas from the DLR (German Aerospace Agency), on how to commercialize remote sensing in Germany.
