Application Of Geographic Information System in Defense Organisations Essay

Application Of Geographic Information System in Defense Organisations (Army, Navy & Airforce) - Essay Example The future soldiers and powerful army will not be able to survive in information technology environment without any availability of information army and GIS. The advancement in army makes sure that modern maps are also present. In fact, the term ‘modern map’ not only mean an up to date map but also includes transparency (that is, being able to be used simply, from the user’s point of view) along with perfect accuracy. The higher-than-average information content is available in order to support military the special military aspects. There is no doubt that any extra element related to information may be needed in order to execute task, planning and implementation. The old maps will face disadvantage due to chase traditional methods. The old traditional method has changed; it is not applicable to complement standard topographic maps along with special information. Thus, in this manner creating thematic maps that helps to gather useless information of the user’ s. on the other hand, the essential mapping background is currently ‘adjusted’ in order to provide special information. ... In order to implement the defense task for the national security, public administration and society it is important to have all the information regarding artificial objects on surface and geometric information of natural objects. Moreover, we have also demonstrates the semantics related to events associated with the domain of remote sensing and image processing. Likewise, the events were incorporated with estimation of vegetation shield by consuming two indexes i.e. using Normalized Difference Vegetation Index (NDVI) and Ratio Vegetation Index (RVI). Moreover, along with these indexes, supervised and unsupervised classification is also conducted that is related to different information classes illustrated on an image. Moreover, these events also include images and pictures that are captured via satellites that are powered with remote sensing technology. The advantage of remote sensing is that it can detect objects in real time along with providing coverage of an expanded area within a short period of time. However, remote sensing can be divided in to two types i.e. active remote sensing and passive remote sensing. The active remote sensing provides an opportunity to be utilized at any time throughout the day and regardless of any season. Moreover, active remote sensing also facilitates the inspection of wavelengths that are not effectively illustrated by the Sun. In addition, it also takes charge of the illumination on the targeted object. On the other hand, passive remote sensing requires the Sun, in order to brighten the objective or the target. Moreover, this type of remote sensing uses reflected waves to measure the distance. As (Smith 2010) states that remote sensing based on active methodology needs a significant amount of energy source
