In recent years, there has been a sudden increase in the utilization and popularity of Free and Open Source Software (FOSS), applications and data sources in the field of Geographic Information System (GIS) and Remote Sensing (RS). The tools and functionalities provided by FOSS are comparable to their proprietary peers. In addition to being free of cost this software has a small learning curve and is customizable. Except for some specialized functionalities, FOSS software provide almost all the tools required by a researcher for a general GIS and RS project. Proprietary software, instruments like Global Positioning System (GPS), camera, etc. and satellite data are usually costly and cover a significant part of the project expenses.
