Software is used to make, examine, and envision geographic data, i.e., data regarding a place on earth is typically indicated by the term ‘GIS software.’

Various GIS capabilities are required for multiple applications, and various classifications of GIS software exist, giving a specific arrangement of capacities expected to satisfy particular data tasks.


Various types of GIS software exist with various usefulness. Most GIS software is categorized into the following classes:

  1. Web GIS
  2. Spatial Data Base Management System (SDBMS)
  3. Mobile GIS
  4. Libraries & Extensions
  5. Desktop GIS


WebGIS is an advanced type of Geospatial Information System (most regularly known as Geographic Information System) accessible on the web platforms. Web GIS is a distributed data framework, counting a client and a server, where GIS is a server, and a client is a web program, Desktop application, or Mobile application. In its most un-complex structure, to make communication between server and client, web GIS can be portrayed as any GIS that utilizes web innovation.

Web GIS empowers a non-master GIS clients to helpfully team up with map representations and answer their requests without including a GIS community. WebGIS conveys GIS heavily influenced by the people. It diminishes the need to make a custom application. Presently web maps can be made for a low cost, utilizing a point and snap interface very quickly utilizing just an internet browser. It gives a stage to coordinating GIS with different business frameworks and empowers cross-authoritative cooperation. WebGIS permits associations to deal with all their geographic information appropriately.

2. Spatial Database Management Systems (DBMS)

Spatial Database Management Systems (DBMS) are chiefly used to store the information, yet frequently give (restricted) analysis and information manipulation facility.

3. Libraries and Extensions 

Libraries and Extensions give extra (investigation) usefulness that isn’t essential for the fundamental GIS programming, for example, functions for the landscape analysis, or capacities to peruse detailed information designs.

4. Mobile GIS

Mobile GIS is frequently utilized for field data gathering.



Desktop GIS typically serves all GIS tasks and is once in a while arranged into three usefulness classifications:GIS Viewer, GIS Editor, and GIS Analyst.

Desktop GIS can give essential GIS functions, for example, information input, map presentation, spatial inquiry, attribute question, and spatial investigation. Most open-source desktopGIS applications can be installed on various working structures (Windows, MacOS, Linux, etc.). Desktop Gis software is complex; the ideal approach to learning is through an issue/arrangement approach. Instead of attempting to pick up everything, it’s prepared to do, and it’s the best beginning with sorting out the parts relevant to the issues that needed to solve. Such as,

  • Making representations, category maps/ quantity maps/heat maps, etc
  • Queries solving and picturing the outcomes
  • Linking Spreadsheets to map data
  • Geocoding addresses
  • Altering the feature’s attribute information and geometry


The two most popular and frequently used Desktop GIS Software by a wide margin are ArcGIS and QGIS. Both offer comparative usefulness, yet some significant dissimilarities exist regarding how they are distributed and their encompassing environments.

  • ArcGIS

ArcGIS for Desktop developed by Esri is a commercially available set-up of programs incorporating three desktop variants, including ArcMap, ArcCatalog, and ArcToolbox. By using these applications and interfaces incorporated, one can play out any GIS task, simple to the front line, including arranging, geographic assessment, data adjustment and collection, information management, visualization, and geoprocessing.

  • QGIS

QGIS is the only free GIS software that is practically identical to ArcGIS. It is used for basic GIS activities like map-making and geospatial examination, just as more explicit assignments like catastrophe hazard prevention, territory investigation, and natural resource planning. QGIS is created as a paid center of engineers yet, also depends partially on volunteers.

The Functionality of Basic Desktop GIS Software

all Desktop GIS frameworks have similar usefulness, which is usually needed for new GIS user’s requirement; some of the standard functions of map-making include:

  • Stacking and Styling Layers

Most maps comprise different layers piled up on top of one another containing graphics recognizing the map’s shadings, fills, and strokes to visualize what each feature represents.


    •  Stroke

The stroke is used for lines, points, or polygons’ boundary lines to control the lines’ shading, thickness, and style. Similarly, stacking various lines styles on top of each other makes some charming composite styles. The strokes can similarly be changed reliant on the attribute data. For example, a layer called “Streets” and the data tied may be a Highway, Major Road, Minor Road, Residential Road, or Track. Accordingly, one can adjust the style contingent upon the prerequisite.

    •  Fill

A fill can be used for either a polygon or a point. Fill styles are incredibly fascinating as they impart two sets of data simultaneously by stacking layers.

    • Labels

Lines, points, and polygons are named in a GIS. The text style, size, and diagram, and color can also be adjusted.

  • Attribute and Spatial Query

An attribute query is a way of searching and recovering data of features in an information base system dependent on the required characteristic qualities. For instance, extract the pixel of 200 values indicating snow. In contrast, Spatial query alludes to recovering an information subset from a map layer by working directly with the map features.

  • Editing and Creating Features

A GIS offers to add, alter, and delete features.

    •  Altering Features

GIS can be utilized to alter and remove geometry. The positions of points can be changed, the state of lines and polygons can be altered by clicking and moving vertices. Features can also be parted and joined inside a layer.

    • Making New Features

A source or base map is required to make new features, such as a satellite image that allows GIS-user to draw point or follow a line or polygon. This technique is known as digitization.\
