Ferret Live Access Server (LAS), a Web-based Data Visualization and Analysis ToolEntry ID: 01-ferret-00
Abstract: Ferret is an interactive computer visualization and analysis environment designed to meet the needs of oceanographers and meteorologists analyzing large and complex gridded data sets. It runs on recent Unix and Mac systems, using X windows for display. PyFerret, introduced in 2012, is a Python module wrapping Ferret. The pyferret module provides Python functions so Python users can easily take ... advantage of Ferret's abilities to retrieve, manipulate, visualize, and save data.
Ferret and PyFerret can transparently access extensive remote Internet data sources using OPeNDAP; see http://opendap.org and http://www.unidata.ucar.edu/publications/directorspage/UnidataOverv....
Ferret was developed by the Thermal Modeling and Analysis Project (TMAP) at PMEL in Seattle to analyze the outputs of its numerical ocean models and compare them with gridded, observational data. The model data sets are generally multi-gigabyte in size with mixed multi-dimensional variables defined on staggered grids. Ferret offers a Mathematica-like approach to analysis; new variables may be defined interactively as mathematical expressions involving data set variables. Calculations may be applied over arbitrarily shaped regions. Fully documented graphics are produced with a single command.
Many excellent software packages have been developed recently for scientific visualization. The features that make Ferret distinctive among these packages are Mathematica-like flexibility, geophysical formatting, "intelligent" connection to its data base, memory management for very large calculations, and symmetrical processing in 6 dimensions.
