This document lists and describes several open source GIS and remote sensing software packages. It discusses desktop GIS programs like GRASS GIS and gvSIG that provide tools for spatial data analysis. It also outlines remote sensing software for processing satellite imagery, including SAGA GIS, Opticks, GRASS, PolSARPro, ORFEO, OSSIM, and ILWIS, that support functions like image classification, filtering, and change detection. Many of these programs offer large libraries of processing modules and capabilities for handling different data formats and projections.

1. Commercially Available
Remote Sensing and GIS
Software
Presented by :
Anuj Kumar

2. Description
GIS software encompasses a broad range of
applications, all of which involves the use of
some combination of digital maps
georeferenced data.
 Below is a list of notable GIS software
applications.

3. The following open source desktop GIS
projects are :-
GRASS GIS – Originally
developed by the U.S.
Army Corps of
Engineers, open
source: a complete GIS

4. SAGA GIS – System for
Automated
Geoscientific Analysis- a
hybrid GIS software.
• SAGA has a unique
Application
Programming Interface
(API) and a fast growing
set of geoscientific
methods, bundled in
exchangeable Module
Libraries.

5. gvSIG – Open source
GIS written in Java.
• It is a Geographic
Information System
(GIS), that is, a desktop
application designed
for capturing, storing,
handling, analyzing
and deploying any kind
of referenced
geographic
information in order to
solve complex
management and
planning problems.

6. Whitebox GAT – Open
source and transparent
GIS software
• Whitebox possesses a
new process for
accessing spatial data
that allows for the
processing of much
larger (massive) spatial
datasets.

7. Capaware – Capaware is
also an Open Source GIS,
an incredible fast C++ 3D
GIS Framework with a
multiple plugin
architecture for
geographic graphical
analysis and visualization.

8. IDRISI – GIS and Image
Processing product
developed by Clark Labs
at Clark University.
• Affordable and robust, it
is used for both
operations and
education.

9. FalconView –
FalconView is a
mapping system
created by the Georgia
Tech Research Institute
for the Windows family
of operating systems.
• A free, open source
version is available.

10. Satellite and aerial imagery provides
answers for environmental change,
weather forecasting, disaster
management, food security and more.
Remote sensing software processes
images and provides solutions to local
or global issues.

11. • THESE SOFTWARES ARE FOR PUBLIC
USE AT NO COST.
•Here is the list of open source remote
sensing software packages :-

12. 1. SAGA GIS: System for Automated
Geoscientific Analyses
 SAGA GIS is on the top of the list and for
good reason. The main reason being: SAGA
GIS is ideal for most GIS and remote sensing
needs.
 A rich library of modules gives SAGA GIS a
big advantage. These modules come in the
form of raster analyses and manipulation.

13. 2. Opticks
Opticks might be that magic bullet that you’re
looking for in open source remote sensing
software.
The neat part about this software is the long
list of extensions you can add. There are
plugins for raster math, radar processing and
hyper/multispectral.

14. 3. GRASS: Geographic Resources
Analysis Support System
GRASS is full of functionality: image
classification, PCA, edge detection,
radiometric corrections, 3D, geostatistics
analysis and filtering options.
Another key feature of GRASS is the LiDAR
processing and analysis. You can filter LiDAR
points, create contours and generate DEMs.

15. 4. PolSARPro
This software can handle dual and full
polarization SAR data. The SAR data can come
from ENVISAT-ASAR, ALOS-PALSAR,
RADARSAT-2 and TerraSAR-X.
 There’s a wide range of tools like importing,
conversion, filtering, decompositions,
inSAR processing and calibration.
The important part of this software is
the graph processing framework where users
can automate workflow.

16. 5. ORFEO: Optical and Radar
Federated Earth Observation
It is a library of remote sensing image
processing specifically aimed at high spatial
resolution.
 ORFEO provides a wide range of remote sensing
functions: radiometry, PCA, change detection,
pan sharpening, image segmentation,
classification and filtering.
The most important aspect of this software is the
capability to do object based image analysis.

17. 6. OSSIM: Open Source Software
Image Map
OSSIM is a high performance open source
remote sensing software application.
Some of the key features is compatibility
with more than 100 raster and vector
formats and over 4000 different projections
and datums.

18. 7. ILWIS: Integrated Land and Water
Information System
ILWIS was originally built for researchers and
students. For this reason, effort was
concentrated on developing a user-friendly
environment.
The other main focus was compatibility with
raster and vector formats.
