5. Types of GIS software

Various types of GIS software exist, each with their own strengths and weaknesses. For the purpose of this paper, we will focus on and discuss one commercial off-the-shelf GIS (COTS GIS) software, ArcGIS, and one Free and Open Source GIS (FOSS GIS) software, QGIS. These two software suites were chosen due to their popularity and use in the field of GIS. Throughout the next sections, some basic functions of GIS will be introduced and explained.
