Applications of Geographic Information System - Part 2

 Assessment of Flood Damage: When necessary, GIS helps in documenting the need for government disaster relief money and can be used by insurance companies to help determine the financial value of property loss. A local authority must map flood-prone areas in order to assess the amount of flood danger in the neighborhood. Digital maps can be used to demonstrate the damage and to accurately assess it.

 

Navigation: Web-based navigational devices promote secure waterway travel. For improved navigation, ferry paths and cargo routes are defined. Accurate topography and hydrographic data are provided by ArcGIS, which also supports safe navigation systems. Recently, the Coastal Resources Division of the DNR started the process of using GIS to find, categorize, and record these non-historical wrecks. To reduce the risk of accident and harm, the web map will be frequently updated to notify boaters of these coastal risks.

Determine changes in land use/land cover: The term "land cover" refers to the features that covers an uninhabited area. Land use is the portion of the surface that is put to a specific use. GIS technology is used in land use and land cover applications so that we can track changes in land use and land cover across various regions. Additionally, it can track and estimate changes in the pattern of land use and land cover over time. It makes it possible to identify unexpected changes in land use and land cover brought on by either natural factors or human activity, such as deforestation.

 

GIS-based Landslide Hazard Zonation: Zoning an area according to the levels of actual or projected landslide risk is known as landslide hazard zonation. It is a difficult undertaking to assess the risk of landslides. It is now possible to effectively gather, modify, and integrate a wide range of spatial data, including geological, structural, surface cover, and slope features of an area, which can be used for hazard zonation. GIS can easily combine the full aforementioned layer, and weighted analysis is useful for identifying areas that are prone to landslides. With the aid of GIS, we can analyze risks and lessen the loss of life and property.

Management and Mitigation of Disasters: A sophisticated GIS system is being employed to safeguard the environment. It has evolved into an effective, well-developed, comprehensive solution for disaster management. By showing which areas are likely to be vulnerable to natural or man-made disasters, GIS can aid in risk management and analysis. Preventive measures can be created whenever such events are discovered.

Applications in Agriculture: GIS may be utilized to develop farming methods that are more productive and efficient. Additionally, it can evaluate soil data to select the best crops to plant and where to plant them. How can nutrient levels be maintained to best benefit plants and crops? It is completely integrated and well-liked for assisting government organizations in running programs that aid farmers and safeguard the environment. This might boost food production in various regions of the world, preventing a global food catastrophe.
