CONTEXT

The initiative development of PolSARpro Software is a direct
result of recommendations made during the POLinSAR 2003
Workshop held at ESA-ESRIN in January 2003.

2003 2004 2005 2007

PolSARpro v4.0 SOFTWARE
The Polarimetric SAR Data Processing
and Educational Tool v4.0

Tool specifically designed to handle : Polarimetric data and
Polarimetric Interferometric data.
Educational Software offering a tool for self-education in the
field of POLSAR and POL-InSAR data processing and analysis.
Developed to be accessible to a wide range of users, from PhD
students to experts in the field of Polarimetry.


USER INTERFACE

PolSARpro v4.0 Software is conceived as a
flexible environment, with a friendly and
intuitive Graphical User Interface (GUI)

The graphical user interface (GUI) is written in Tcl-Tk

- 331185 lines managing 189 widget windows

- 1078 C routines (464803 lines) performing well-
established algorithms in the field of POLSAR and
POL-InSAR.

MODULAR STRUCTURE
Each element of the Software (a function)
can be extracted and incorporated
individually into users’ own processing
software.

MODULAR STRUCTURE
Users can easily add their own functions and
components, as PolSARpro v3.0 Software is
conceived as a flexible and open software
environment.

OPEN SOURCE DEVELOPMENT
PolSARpro v4.0 Software is made available
following the:
Open Source Software Development (OSSD)
approach, and follows the:
GNU General Public License v2 – June 1991.

PolSARpro v4.0 Software runs today on:
Windows 98+, Windows 2000, Windows NT 4.0,
Windows XP, Linux I386 and Unix SOLARIS

Macintosh OS:

OPEN SOURCE DEVELOPMENT
The Tool is free download on the Internet
from the ESA Web Portal (Earthnet) at :
