Voronoi Diagram: How can GIS Help you Identify the Distance Between Places and the Closest Point?
Voronoi Diagram is one of the most crucial components of the geographic information system. The tool is used for identifying the nearest location to the target. Let’s say you are calling someone. Your network provider service is connected to a couple of cell towers in your location. Now, how do you know which tower your network will connect to? If there is no difference between these towers, your mobile will most likely connect to the one located close to it.
Coming to the important question, “how do you figure out which tower is located close to your mobile phone”? That’s where the Voronoi Diagram comes into the picture. It helps in the identification of the tower located closest to your mobile. Let’s check out how the Voronoi Diagram is used.
How can it Be Used for Tracking the Airport?
Now that you know what a Voronoi Diagram is and how it can be used for locating the cell tower, let's take a look at how it works for locating the airport.
With the help of the polygon, you can get a clear picture of the airports located close to you. For example, if you need to find the airport located close to where you are now, you can use Voronoi Diagram. Voronoi diagrams are not colorful pictures, but they are pretty useful. As mentioned earlier, these diagrams are extensively used for identifying the proximity of things and measuring the distance of certain features.
This GIS-based remote sensing tool was developed by Georgy Voronoi. Not only does it help you track the distance between the airport and your current location, but Voronoi Diagram is widely used in the fields like Biology, geoscience, and networking.
How is GIS Used in Voronoi Diagram?
It may look like a new tool, but the Voronoi Diagram has been in the industry since the 19th century. These are basically the convex polygons. The most popular approaches for defining the Voronoi diagrams are raster and vector. Because of the complexity of the vector method, most researchers and scientists using Voronoi Diagrams have started implementing the raster-based approaches.
A few of the challenges concerning these polygons that researchers have recently addressed include the complex Voronoi diagram for Earth’s surface. It is also possible to calculate the distance between land surfaces with the help of these Voronoi shapes. While these approaches are widely used in today’s times when the distance between airports is calculated, they may or may not always work. In fact, the results generated from these distance measurement tools are most often inaccurate.
As mentioned earlier, Voronoi Diagram has a plethora of uses in nearly every industry. 3D GIS, for example, can help you identify the camera positioning for security reasons. In addition to that, this remote sensing tool has been recently used in identifying the socio-economic relationships between educational institutions in China. Voronoi diagrams have also gained popularity in visualizing spatial data in other fields.
