Isoline Retrieval uses supervised statistical classification to retrieve isolines from cross-track scanning or similar satellites. It contains software to generate training data using collocation or radiative transfer simulations, as well as routines to interpolate the final fields using a variation of multi-linear interpolation or kernel estimation. The currently-supported satellites are the Advance Microwave Sounding Unit (AMSU) series and, to a lesser extent, the Global Ozone Measurement Experiment (GOME). An ambitious researcher, however, could easily adapt the codes to a similar satellite.
Sea Ice is software for modeling the microwave emissivity of sea ice. It includes two plane-parallel radiative transfer models: a Monte Carlo ray tracing simulation that models ridged ice, and thermodynamic models that can be used to generate input to the emissivity models in the form of temperature and salinity profiles. It is written in C++ and Interactive Data Language (IDL). It has been used to generate results for several papers on sea ice emissivity.
HEALPix is a set of scientific tools implementing the Hierarchical Equal Area isoLatitude Pixelation of the sphere. As suggested in the name, this pixelation produces a subdivision of a spherical surface in which every single pixel covers the same surface area. HEALPix provides various programs and libraries in C, C++, Fortran, GDL/IDL, Java, and Python which facilitate discretization, simulation, processing, analysis, and visualization of data on the sphere up to very high resolution. It is the state-of-the-art program used in astronomy and cosmology to deal with massive full-sky data sets.
GetData is a library that provides an API to interface with dirfile databases. The dirfile database format is designed to provide a fast, scalable format for storing and reading binary, synchronously-sampled, time-ordered data. GetData was originally written for the BOOMERanG and BLAST experiments as a data format suitable for use for both quick-look and data reduction. It is now used by many other cosmological and astrophysical experiments including ACT, Planck, Spider, Keck, as well as other projects.
Opticks is similar to commercial tools like ERDAS IMAGINE, RemoteView, ENVI, or SOCET GXP. Unlike other competing tools, you can add capability to Opticks by creating extensions. It supports the following file formats: NITF 2.0/2.1, GeoTIFF, ENVI, ASPAM/PAR, CGM, DTED, Generic RAW, ESRI Shapefile, HDF5, AVI, MPEG, JPEG, GIF, PNG, and BMP. It can zoom, pan, or rotate spatially large datasets. It can quickly layer GIS features, annotations, results, and other information over your data to provide context. It has many image display controls such as colormap, histogram, transparency, etc. Support for datasets larger than four gigabytes. Analysts can quickly combine steps using graphical wizards. Support for processing data in its native interleave of BIP, BSQ, or BIL. Extensions can add new processing algorithms, file formats, visualizations of the data, or data types.
Opticks Extras is a set of official extensions for the Opticks application. The Spectral Processing extension adds multi-spectral and hyper-spectral processing capability to Opticks. The IDL Scripting extension integrates an IDL interpreter directly into the Opticks application. The Python Scripting Extension integrates a Python interpreter directly into the Opticks application.
MyRPC is a remote procedure call framework designed to easily connect heterogeneous systems. It features IDL-based client and server stub generation, cross-platform capability, binary protocol (no need for escaping of binary data, less overhead), support for various data types (like string, binary, signed and unsigned integers, floating point, list, structure, and enumeration), and exception support. It has no external dependencies.
