GIS is the abbreviated form of Geographical Information System. This is controlled by computerized technology and helps to find out the details of a geographical location. This task covered by GIS is to collaborating new data with existing one, and analyzing human usage of physical environment, which primarily relates to ecology, geology, demography, transportation, land use, etc. In this a process called geo-coding which enables to digitized data converted into possible geographical images over the map. The main techniques used in GIS are as follows:-

• Data Creation
• Relaying Information
• Data Representation
• Data Capture
• Graphic Conversion ~ From Raster to Vector
• Data Modeling
• Data Binding
• Cartography
• Geo-statistics
• Geo-encoding
• Geo-software

and many more.

GIS is practically a promising and developing field, which, in time, will be beneficial for the development of many other disciplines, including, business, criminology, national defense, public health, natural resource etc.

It is the short-form of Geographic Information System, where this system captures, records, stores, analyzes and presents data that are linked to different locations across the globe. It is the merging of geographical processes like cartography, statistical analysis and data management. This system can be used in geology, geography, navigation, aviation, urban planning, land surveying and remote sensing etc.

GIS stands for Geographic Information Systems.  It handles geographic vectors consisting of points, lines and polygons.  It is also made up of raster images which could come from satellites, UAV and aerial photography.

Using this data, a Geographic Information System also consists of GIS software that can do 4 simple ideas:

1) Create geographic data.

2) Manage it.

3) Analyze

it and…

4) Display it on a map.

These are the 4 primordial functions of a GIS. 

This type of system is a rapidly emerging field for decision-support in a range of fields from mining to agriculture.  The output of a GIS is typically a map or type of statistical analysis.

If pictures are worth a thousand words, then maps are worth a lot more.
