    Introduction book Mastering ArcGIS Pro

    This e-book is an encyclopedia for Mastering ArcGIS Pro, as it contains 12 main topics, these topics are divided into many sub-topics, all in 450 pages, and these some topics are covered in the book Mastering ArcGIS Pro:-

    What is GIS?

    GIS stands for geographic information system. In practical terms, a GIS is a set of computer tools that allows people to work with data that are tied to a particular location on the earth. Although many people think of a GIS as a computer mapping system, its functions are broader and more sophisticated than that. A GIS is a database that is designed to work with map data.

    Consider the accounting department of the local telephone company. They maintain a large computer database of their customers, in which they store the name, address, phone number, type of service, and billing information for each customer. This information is only incidentally tied to where customers live; they can carry out most of the important functions (billing, for example) without needing to know where each house is. Of course, they need to have addresses for mailing bills, but it is the post office that worries about where the houses actually ARE. This type of information is called aspatial data, meaning that it is not tied, or is only incidentally tied, to a location on the earth’s surface.
    Employees of the service department, however, need to work with spatial data to provide the telephone services. When hundreds of people call in after a power outage, the service department must analyze the distribution of the calls and isolate the location where the outage occurred. When a construction company starts work on a street, workers must be informed of the precise location of buried telephone cables. If a developer builds a new neighborhood, the company must be able to determine the best place to tie into the existing network so that the services are efficiently distributed from the main trunk lines. When technicians prepare lists of house calls for the day, they need to plan the order of visits to minimize the amount of driving time. In these tasks, location is a critical aspect of the job, and the information is spatial.

    In this example, two types of software are used. The accounting department uses special software called a database management system, or DBMS, which is optimized to work with large volumes of aspatial data. The service department needs access to a database that is optimized for working with spatial data, a geographic information system. Because these two types of software are related, they often work together, and they may access the same information. However, they do different things with the data.
