- **************************** SPHINX 3.44 ***************************
-
- Sphinx is a user-friendly, state-of-the-art image processing
- and analysis package that runs across a spectrum of high performance
- computer platforms operating UNIX and the X-Window System.
-
- It was created to meet to the daily research needs of scientists
- conducting climate investigations using satellite data and remote
- sensing techniques.
-
- Intuitive Graphic Interface
-
- Sphinx features an interactive interface with pop-up menus and
- point-and-click dialog boxes which makes image processing and
- analysis simple and fast.
- This accessible menuing enables you to build attractive image
- layouts quickly while also providing you the flexibility of returning
- to the main menu to conduct other image analysis and processing operations.
-
- Image Format Compatibility
-
- Using smart read/write functions, Sphinx allows you to easily open
- and save image files in a variety of formats using bit, integer or real
- data values. Sphinx also reads and writes the common TIFF and GIF formats
- as well as compresses and decompresses image formats to save disk space.
-
- Image Analysis & Processing
-
- For image and pixel analysis, the Sphinx package includes an
- assortment of processing tools that perform useful statistical and
- mathematical filtering operations, such as Fourier transforms, convolution
- product or principal component analyses.
- An interactive interpreter for both algebraic equations and images allows
- the user to manipulate and combine individual data channels interactively.
- Standard FORTRAN notation is used for formula entry and for trig
- onometric and transcendental functions.
-
- Satellite Spectra & Orbit Analysis
-
- Sphinx possesses functions to simulate satellite signal sensitivity
- for various meteorological satellites (e.g., GOES, METEOSAT, NOAA, Spot etc.).
- The simulations are conducted for a selection of standard atmospheric and
- surface conditions and instrument spectral bands.
- A geometry model computes the solar zenith angles, warping, orbit simulation,
- and 3-D image projection.
-
- Easy External Program Interfacing
-
- Sphinx allows users the flexibility to integrate externally
- developed software algorithms for processing and converting satellite
- observations. Sphinx exports and imports image files and image parameters
- to external programs using special interface functions.
-
- Quick Quality Presentation
-
- Sphinx rapidly displays, manipulates, and enhances high-resolution
- multispectral images and color tables. Using six 8-bit 1024x1024 image
- planes and one graphics plane, the package conveniently combines color images,
- graphics and text to generate sharp digital images for articles and reports.
- Sphinx's 2-D and 3-D graphics editor provides complete flexibility for modifying
- and integrating vector graphics and analysis plots with images, such as
- histograms and radial graphs. The package supplies color and gray scale
- output for standard inkjet and laser printers.
- Other Capabilities Sphinx also performs image animation, external
- graphics importing, mosaic fitting... what else?
-
- Software Support & Development
-
- Sphinx was developed at the Laboratoire d'Optique Atmospherique (LOA)
- of the Universite de Lille, France.
- The package has received critical feedback and support from scientists at
- the French national laboratory, Centre National de Recherche Scientifique (CNRS),
- and the French space agency, Centre National d'Etudes Spatiales (CNES).
- At LOA, Sphinx undergoes continued refinement and development to meet changing
- research needs and advances in computer technology. The package, which features
- on-line help, is supported by an Internet address
-
- sphinx@loasil.citilille.fr through which questions can be answered and
- version updates provided without delay.
-
- Performance Tested
-
- CNES has selected Sphinx to analyze and process the satellite data
- collected during the upcoming ADEOS/POLDER satellite mission. Today,
- the Sphinx package is in use at the NASA - Goddard Space Flight Center
- and is widely used in many French laboratories, including
- the Centre de Recherche en Physique de l'Environnement, Ecole Normale Superieure ,
- Laboratoire d' Etudes et de Recherches en Teledetection Spatiale, Laboratoire
- de Meteorologie Dynamique.
-
-
- A TEST VERSION OF SPHINX IS AVAILABLE AT loasil.citilille.fr
- (134.206.50.4) anonymous (bin : cd SPHINX : get ALL_SPHINX3.44.tar.Z)
-
- IN THE TEST VERSION THE OUTPUT FILES ARE DISABLE. HOWEVER THE
- VISUALISATION AND GRAPHIC FUNCTIONS ARE AVAILABLE. THIS IS
- SUFFICIENT TO WORK WITH.
