Practical Uses of Geographical Information Systems
Today’s world has a lot of new inventions. One of these inventions is the Geographic Information System or GIS. Geographic wise, this system compiles huge amounts of data. Before the last step of displaying the info, the system initially gathers, scrutinizes, interprets, sorts and distributes the said data. The display is done digitally. This system is specifically for the geographical features that include all sorts of terrain and elevations. This data is so important and its use is invaluable.
There are so many applications of GIS. The most obvious one is the generation of real-time maps. However, this is not the only use of the system even if it is the only one known by many. On the other hand, maps have numerous applications as well. Plans are used in construction, allocation of land, searching, planning, and so much more. Mapping takes different forms like aerial imagery.
In scientific investigations, GIS is still applicable. Geographical info of the area in question must be studied before any exploration or excavation is done. Urban planning, forestry, oil and gas mining, agriculture, and environmental assessments are just some of these activities.
Land planning is also another area where the information from the system is useful. As land planning is a broad field, what is entailed here is all sorts of survey, construction, and land reclamation. Before any step can be taken, the engineers on the ground must first assess the geographic info of the are. This involves getting the prevailing data from the GIS.
Any changes present on the surface of the earth are easily detected via the thermal imaging of the GIS. Earthquakes are easily detected and mapped due to this feature. Any sort of tectonic shift that is significant enough can be detected as well. This way, settlements can be warned of impending danger. The thermal imaging also notes any fissures that might open near volcanic mountains and help observers make the necessary steps.
GIS is also used to study climate. Shifts in winds, temperature and other weather patterns affect the surrounding area tremendously. The system gathers all this data and helps predict any climatic change. For instance, the melting of ice in the Arctic has been studied for a long time via GIS.
When security comes into play, GIS is still applicable. The environment is the first in line to be secured. All projects that involve the land like construction need to be done where they cause less harm to the environment. On the same note, the geographical information is phenomenal in tracking any kind of natural disaster. Before forest fires, volcano eruptions, earthquakes, tsunamis and the like can happen, they can be detected. When need arises, this info will see response teams well prepared.
