Geographic Information Systems (GIS) is a system that created to “capture, store, manipulate, analyze, manage, and present all types of geographical data” (Research Guides, n.d.). The nature of the data used in the GIS system is that it possesses a spatial dimension. GIS is used to analyze remotely sensed data, and assist in solving problems as well as effective decision-making. Geographers can analyze HIS information to establish the exact location of certain features and their density.
Cartography is simply the practice of designing or making maps. The main purpose of cartography is formulating an agenda as well as choose the features of the object to be mapped (Britannica Encyclopedia, n.d.). It is also intended to represent the terrain of the mapped area. Whenever there are elements in the object that do not suit the agenda of the map, they are removed. In geography, cartography is used to create maps to locate certain physical features such as water bodies, mountains, rivers, etc.
Remote sensing is a process of using radiation emitted or reflected by an object to determine, monitor, or detect its physical traits. The exercise is achieved using a special camera that can take pictures using emitted radiation (USGS, n.d.). Geographers utilize remote sensing in assessing the features of a certain area, such as forest, from a distance. This is useful in determining the density of trees across the forest.
