WebGIS is an advanced form of geospatial Information System.
The web has revolutionized every aspect of information distribution, be it news, video, the encyclopedia or how we communicate.
A webGIS is computer software and hardware configuration that allows the sharing of maps, spatial data, and geographic processing operations throughout one’s own network and beyond using common web communications protocols such as HTTP (Dragićević, 2004)
The exchange of information takes place between a server and a client, where the server is a Geospatial Information System (GIS) server and the client is a web browser, mobile application and desktop application.
The server has a unique Uniform Resource Locator (URL) so that clients can find it on the web. WebGIS brings GIS into the hands of the people.
Web GIS isn’t about outperforming desktop GIS or even competing with it. It’s about making the power of GIS available to everyone.
Web GIS reduces the need for end-users to install sophisticated software to work with geographic information, as most operations can be performed in web browsers or mobile apps.
A web service is a piece of code that runs on the server and can perform some action in response to a client request.
With the help of the Internet, clients can access the geospatial information over the web regardless of the fact how far the server and client might be from each other.
The geographic data and maps can be presented to the world through WebGIS.
