What Is Open Source Remote Sensing ?

Open Source Remote Sensing

Remote sensing is defined as a technology which provides information about the environment or the phenomenon on the earth's surface which is far away or remotely sensed. A person can get information about the things without any direct as well as physical contact with an object.

Open source remote sensing is a software with a source code which is available for all as a source to learn, to explore and to make use of it. Open sources are the licensed softwares made by many people which are freely available and can be easily used and further modified by anyone for the credits.

SOME SOURCES OF REMOTE SENSING:

IDRISI

Erdas

ENVI

ILWIS

QGIS

Orfeo Toolbox

R

GRASS

SAGA GIS

The above given sources of remote sensing some are free whereas few are not.

ILWI,QGIS for GIS, Orfeo toolbar, R,GRASS,SAGA are some of the free or open sources for remote sensing whereas IDRISI,Erdas,ENVI are not free.

Ques. How open source software is useful?

Ans.  It is enourmously useful to the people who even have a little          knowledge about this. It is available free of cost with license that means it avoids expense. It can be used by anyone and can also be further modified for the credits.

Ques. What are the objectives of open source?

Ans.  There are many objectives like:

1. People who are new to this field can gain knowledge about this and is also theoretically   beneficial to them. 
2. Through this open source lectures can be delivered to the students in the lab.
3. The changes can be made in the software and can be generated further.
4. It can be very helpful for the research scholars to carry out their research in a good and technical manner. 

Ques. What are the best open source for remote sensing?

Ans.  The best open source for remote sensing are QGIS 2.0.1 "Dufour",GDAL 1.9.2, GRASS GIS 6.4.3,Orfeo Toolbox 3.18, R 3.0.2 and SAGA 2.1.

Ques. What are the microsoft windows in which open source can run? 

Ans.  Linux, windows, windows Vista, windows Azure, etc are some of the microsoft windows that support open sources and the applications like JAVA and C++ makes the software easily run.
