Geographic Information System
- GIS stands for Geographic Information System.
- It's a system designed to collect, analyze, manipulate, manage, and display all kinds of geographical and spatial data and information.
- It allows you to perform spatial analysis and manage large data and display the information in maps or graphical form for analysis and presentation.
- These benefits make GIS a valuable tool to see spatial data or to build decision support systems for a corporation.
- A GIS stores data on geographical features and their characteristics. These features are referred to as points, lines, areas, or raster images.
- For ex, In the map of a city, road data are often stored as lines, and boundaries are often stored as areas, and aerial photos are often stored as raster images.
- GIS store information using spatial indices that permits identifying the features located in any arbitrary region on a map.
- For ex, a GIS can quickly identify and map all of the locations within a specified radius of some point, or all of the streets or roads that undergo a territory.
- GIS provides the potential to relate previously unrelated information, through the utilization of location because the "key index variable".
- Locations and extents that are found within the Earth's spacetime, are ready to be recorded through the date and time of occurrence, along side x, y, and z coordinates; representing, longitude (x), latitude (y), and elevation (z). All Earth-based, spatial-temporal, location and extent references, should be relatable to at least one another, and ultimately, to a "real" physical location or extent.
- This key characteristic of GIS, has begun to open new avenues of scientific inquiry and studies.
- Some data are often spatial (locations on the earth), coupled with tabular data (attribute data). Attribute data generally refers to additional information about each of the spatial features.
- For ex, the particular location of the hospitals during a geographic area is spatial data. Additional data like hospital name, level of treatment, and bed capacity are the attribute data. So, GIS may be a combination of those two data types that makes it an efficient problem-solving tool through spatial analysis.
- GIS not only tells the situation of features but also provides additional information associated with a feature such as:
- Relationship of a feature with other features
- Where the most or least of a feature exists
- The density of features during a specific space
- What is happening inside a neighborhood of interest (AOI)
- What is happening nearby some features
- How a neighborhood has changed over the years
- For example, a rare species of a plant is found in three different places, and spatial analysis shows that the plants are only on the south-facing slopes above an elevation of 1,500 feet and obtain quite fifteen inches of rain per annum.
- So, with the help of GIS maps, we will display all locations within the area that have similar conditions and may search for this plant species.
- Similarly, we will determine the locations of farms that are using a specific fertilizer, and therefore the location of streams and rainfall to find out which streams may carry the fertilizer downstream.
