PolSARpro v4.0 SOFTWARE

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

CONTEXT

The Polarimetric SAR Data Processingand 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 PhDstudents to experts in the field of Polarimetry.

PolSARpro v4.0 TEAM

In collaboration with :

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 andPOL-InSAR.


MODULAR STRUCTURE

Each element of the Software (a function) can be extracted and incorporatedindividually 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.


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

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.


OPEN SOURCE DEVELOPMENT

The Tool is free download on the Internetfrom the ESA Web Portal (Earthnet) at :
