Tool Description
COVE The CEOS Visualization Environment (COVE) is a browser-based suite of tools for searching, analyzing and visualizing actual and potential satellite sensor coverage.

The Database for Imaging Multi-spectral Instruments and Tools for Radiometric Intercomparison (DIMITRI) manages L1 data from various medium resolution imagers over terrestrial targets chosen for their radiometric properties and/or the availability of in-situ radiometric measurements. DIMITRI comes with a suite of tools that allow comparison of the L1 data originating from various sensors in the database at Top Of the Atmosphere (TOA) level

ESOV NG ESOV - the Earth Observation Swath and Orbit Visualisation tool - provides users with the means to visualise the instrument swaths of all ESA Earth Observation Satellites and assist in understanding where and when satellite measurements are made and ground contact is possible.
libRadtran libRadtran - library for radiative transfer - is a collection of C and Fortran functions and programs for calculation of solar and thermal radiation in the Earth's atmosphere. libRadtran is freely available under the GNU General Public License.
LPCS The USGS Land Product Characterization System (LPCS): The LPCS facilitates the application of multi-satellite and in-situ data for characterization and validation of satellite-derived land-related products.
MODTRAN The MODTRAN® (MODerate resolution atmospheric TRANsmission)  was developed and continues to be maintained by Spectral Sciences, Inc. (SSI) and the Air Force Research Laboratory (AFRL). The code is embedded in many operational and research sensor and data processing systems, particularly those involving the removal of atmospheric effects, commonly referred to as atmospheric correction, in remotely sensed multi- and hyperspectral imaging (MSI and HSI)
OLIVE The OLIVE (On Line Interactive Validation Exercise) platform is dedicated to the validation of global biophysical products such as LAI (Leaf Area Index) and FAPAR (Fraction of Absorbed Photosynthetically Active Radiation). It was developed under the framework of the CEOS (Committee on Earth Observation Satellites) Land Product Validation (LPV) sub-group.

A common architecture for all Sentinel Toolboxes is being jointly developed by Brockmann Consult, Array Systems Computing and C-S called the Sentinel Application Platform (SNAP). The SNAP architecture is ideal for Earth Observation processing and analysis due to the following technological innovations: Extensibility, Portability, Modular Rich Client Platform, Generic EO Data Abstraction, Tiled Memory Management, and a Graph Processing Framework.

Streamer Streamer is a radiative transfer model that can be used for computing either radiances (intensities) or irradiances (fluxes) for a wide variety of atmospheric and surface conditions.
TELIMAGO Software development platform includes various libraries and standard image processing applications by GAEL System
THE CEOS  DATABASE CEOS Mission, Instruments and Measurements database.
USGS APPEEARS The Application for Extracting and Exploring Analysis Ready Samples (AρρEEARS) offers a simple and efficient way to access and transform geospatial data from a variety of federal data archives. AρρEEARS enables users to subset geospatial datasets using spatial, temporal, and band/layer parameters.
WOPP The Water Optical Properties Processor (WOPP) allows calculation of the inherent optical properties of pure water at atmospheric pressure and at a specific water temperature and salinity, namely absorption (absorption coefficient), scattering (scattering coefficient for any angle, for back -, forward-, and total scattering) and real part of the index of refraction. It was developed by GKSS.
