What is a geographic information system (GIS)? What purpose does it server? Name the two major elements that are combined to make up a GIS.

Answer 1

   GEOGRAPHIC INFORMATION SYSTEM

Now-a-days we are mostly depending on technologies.If we have a smartphone we can do most of the things without help of anyone.Now we are discussing about one of the major technology.4

Geographic information system is a kind of computesr system for analyzing,keeping,examine the things and show the data referring to places on earth.It is mainly used for analyzing the data.GIS data used in business day to day life.For suppose irrigation and water department uses the GIS data to find the most productive crops using less water usage and diary industries for distributing ang locationg purposes.Before GIS we use some manual methods and only few people had those skills,it also takes so much of time but after using these technology it reduces the time usage and makes analyze the things faster.

Geographic information system is used in different sectors or fields,The main purpose for using geographic information system we can easily analyze the geographical related data for a particular location.It is mostly stores the data in layers and that each layer keeps the data about each feature like transportation,land use,rainfall,farm locations and buildings locations.It also addresses the people about health concerns and also finds the locations for specific matchings.

Other than software and hardware the two major elements that are combined to make up a GIS are

1)Relative Loations of characterstics that means longitudes,latitudes

2)Data about locations and also relations

These two mainly important because if we want to know the geographical information we need to know the relative locations by using these locations we can easily know the land using,agricultural crops production,rainfall for the particular place and they can easily relate all these data and start analyzing.For all thses data we can also know the things that happen on earth.
