The GIS or the Geographical Information System acts as the database for the geographical data. Unlike the GPS, which sends signals and find information about a particular location, the GIS collect the data, stores and analyze it. Then, it will arrange the data to the way users can easily understand the information or data that was gathered.
The GIS is used for storing, capturing, displaying and checking data that is related to the earth’s surface. It has the ability to show various kinds if data in just one map. People can easily analyze, see and understand the relationships and patterns through this technology.
Using the GIS technology, you can compare the locations of various things ad discover their relationship to each other. A concrete example of using the GIS map is that the same map can be included in the sites that are producing pollution including wetlands. The GIS map can be used in determining which wetlands have more risks.
The use of the GIS can help you in identifying information including location. Locations can be expressed and interpreted in different ways such as longitude, latitude, Zip code or address. A wide range of information can be interpreted, compared and distinguished with the help of the GIS.
The Geographical Information system can include the data about the people, including, population, education level and income. It can also include the information about the land, which includes different kinds of vegetation, location of streams, and, different kinds of soils. The information about the sites of factories, schools, farms, electric power lines and roads are what the GIS can give.
The GIS and DATA—those data with different forms can be entered in the GIS and the data that can be found on the map can be included in the GIS. The computerized or digital data can also be entered into the GIS. This only implies that the GIS is allowing different types of data and information n matter what original or source format it has, it will be included and entered in the GIS.
Data capture is the process of putting the information into the GIS. Those data that are in its digital form like images that are taken by most tables and satellites can be easily uploaded to the GIS.
The GIS MAPS—whenever the desired data and information are already included in the GIS system, it can be combined in order to produce a wide range of individual maps that depends on which the data layers are included. The GIS maps are used in showing the information about the density and number.
Integrating the use of the GIS among researchers will definitely give and provide the best information and data that they need. It will enable the researchers to look at the change over time.
The GIS requires knowledge and skills about the process for it is not as easy as you think collecting and analyzing the data. That is why knowing the important things that the GIS gives and provides will be of great help especially to the Research Centers.
