Are you aware of how you get easily on your mobile or fingertips as closest gas station, institution, petrol pump or nearby cinema and restaurants along with its way to reach.. Yes it is due to GIS. This is only one example of GIS; there are many fields or categories where GIS can be implemented & used. Through this article you will come to know in brief what is GIS, what it can do, it’s relevant projects & implementation and its advantages.

Geographical Information System is the most important factor of Smart City and New India vision implementation. GIS Mapping & its system integration is the base of overall getting ready as Smart City and Digital India. It will also be one of the major prime mover & base in the growth of the country. GIS has significant role to play and has good future growth & prospects for upcoming years.

What is G I S

“Geographic Information Systems is a computer-based tool that analyzes stores, manipulates and visualizes geographic information, usually in a map”.

 

A Dictionary of Geography defines a Geographic Information System (GIS) as an integrated, spatial, data-handling program which collect, store, and retrieve spatial data from the real world. These are powerful tools in decision-making, as they can incorporate coordinated data.

In Geographic Information System, we connect data with geography and we understand what belongs where. Because we don’t entirely understand that data until, we see how it relates to other things in a geographic context.

In simple steps, Geographic Information Systems can be specified down to just 4 simple ideas:

1). Generate geographic data. 2). Manage or Control it. 3). Inspect or Analyze it and…4). Exhibit it on a map.

 

Simply Geographic Information Systems connects what with the where clause.

What Can GIS Do

Geographic Information Systems answer important questions regarding location, patterns and trends. For example:

  • Check land features availability: It includes points, lines, polygons and grids. If anyone needs to find the closest gas station or hospital, GIS can show the way for that. Or if someone wants to find an optimal location, person may need traffic volumes, zoning information and demographics.
  • Tell the geographical patterns exist: Ecologists who want to know suitable habitat for any specific, can gain a better understanding by using GPS collars and land cover.
  • Tell the changes have occurred over a given period of time: Previously never been able to understand climate change, thanks to GIS and remote sensing technology.
  • Communicate the spatial implications: If an electricity company wants to build a transmission line, how will this affect nearby homes, the environment and safety. Or if the government needs efficient & transparent house taxation implementation, or at tourism, most of environmental assessments use GIS to understand the landscape.
  • Help in safety concerns: Also, safety concerns can be better evaluated using GIS or GPS such as understanding terrain slope and the probability an avalanche can occur.

GIS mapping services allows us to capture, store, manipulate and analyze geospatial data to combine database, mapping and statistical methods to integrate geo-referenced data for data collection, processing, and management ensuring accurate solutions that allow us to overcome tough challenges pertaining to our project and focus to deliver accurate quality geospatial products to help manage our mapping goals.

For GIS mapping coordinate of different satellite image and vector data layers should be correct. On every GIS project, implementation of ongoing data quality control should be there to ensure that coordinate databases, foreign source data such as geological and topographic maps, GIS data attributes and layers create a truly seamless GIS mapping environment. One of the primary services should be provided during the implementation of a GIS project is the geo-referencing of various GIS data layers for mapping projection. The planning stage of every GIS project involves the use of satellite image data for geographical information systems mapping include:

Defense Mapping, Mineral Mapping, Agriculture Mapping, Pipeline Corridor Mapping, Urban Development, Airport Mapping, Environmental Impact Studies (EIS), Coastal erosion studies, Land Cover Classification, Pre and post 2D/3D seismic surveys, Topographic Mapping, Cadastre Mapping, Disaster Analysis

Our projections as current and future upcoming projects related to GIS

From our point of view and information (Where GIS scope exists), few of the current & future upcoming GIS related projects in Uttar Pradesh are GIS Based Master Planning under AMRUT scheme, GIS Survey UP, House Taxation, Underground Mapping, Zonal Plans, Town Planner Scheme Varanasi and Auto Detection of Construction Activity through Satellite etc.

Advantages of GIS solution

There are many advantages of GIS solutions, which can’t be specified in brief write up, whereas few of them are as follows: 

  • Increase the revenue generation for the respective department & as an overall
  • Enable efficient decision support in planning & maintenance
  • Clarify all ward boundaries & whole town area boundaries on map. Inventory of all infrastructure in the town
  • Clarify town area all streets such as highway, rcc road, interlocking & other type street on hard sheet of map & digital map also.
  • Proper GIS mark on the map like Electric pole, Solar light, Submersibles pump, Hand pump, Well, Park, Administrative Buildings, Bus Stop, Railway Station, Govt. School, Private School, Mandir, Mazid, Idgah, Imambada, Water Body & drainage, Ward-wise Houses etc.
  • Decrease the tax theft and increase tax efficiency, where house taxation has been implemented based on GIS
  • Bring in transparency in tax collection and other relevant areas.
  • The mapping and survey provide a detailed inventory of infrastructure and current status.

  Overall it is the latest technology that also saves time, effort & money into respective fields. Apart from making efforts to bridge the gap between demand and supply, efficient GIS Services of overall country is one of the most important tasks in the current developing scenario which has to be addressed jointly by town & country planners, engineers, scientists, industrialist, community-citizen and the Government. The latest technology includes & also requires high standard of services, instant access to information, efficient transactions, and support, whenever and wherever required. Additional implementation & utilization for GIS technology systems into all the cities, villages, departments, and offices are the need of the hour for effective & efficient services. The aim & attempts should be made to focus on this mission and to achieve the target of providing uninterrupted wide Graphical Information System, Information Technology & Electronics implementation & utilization for all in a most efficient & effective manner. This increased manifold due to encouraging schemes of Government like Digitization of India or Digital India along with New India vision and utilization of more & more IT & Electronic hardware & software, GIS/GPS mapping integration implementation.

As of now to give you brief idea about shape file in arc GIS; simple steps are as follows: * Open ArcCatalog in GIS software tool. * Navigate to your project folder. * From the menu, click on File>New>Shape file. * Give your shape file a name and select a geometry based on what type of features you are trying to draw. * Use the Edit button to select the coordinate system that you are using in your ArcMap project. * Related Shape File will be created. Thanks

The creation of shape file in arc GIS is related to GIS software tool and it can be explained during explanation of GIS software tool. We will try to explain it in later upcoming parts. Thanks
