GIS Technology to Aid in National Mission of Clean Ganga

Introduction

The river Ganga has been the prime source of water in Northern plains in India. Since time immemorial Ganga has been the home of some major ancient cities in India (E.g. Varanasi and Patna). As the population along the river grew in size, consumption of fresh water for various activities such as drinking, cleaning, washing, industrial, agricultural, etc. increased. This lead to stress on water resources all over Ganges watershed with ground water going down year after year. Post liberalization economic boom has also compounded the problem of population explosion which has exaggerated the problem of water resources. There is an urgent need to analyze and monitor current quality parameters of river Ganga so that corrective measures can be taken for the problems.

GIS in Disaster Management

Keeping the current and future scenario in mind, Government of India has launched various programs for effective abatement of pollution and rejuvenation of river Ganga. As all the resources on earth are connected with spatial information, GIS will play a big role in coming years in effective management of water resources. A push has already started in this direction with the launch of National Mission for Clean Ganga.

Uses of GIS - River Management

• Land Resource Management

  • GIS enables officials of Urban Local Bodies (ULBs) to keep a track of activities happening over the area under their jurisdiction hence preventing polluting industry to grow unchecked in the region near a water source.

• Water Waste Management

  • GIS can help ULBs in managing their waste water by streamlining the process of identifying the source of pollution in an area. The wasted water by means of any industrial process can be routed to a drain leading to recycling plants which can be managed through GIS. Using GIS for these processes has an added advantage of spatial report generation wherein capacity of the plant and the pollution generating industries can be balanced out for optimal use of the resource.

• Solid Waste Management

  • Solid waste in river Ganga increases due to industrial, cultural and social causes. GIS can help in planning ways in which these can be cleaned out in timely and cost effective manner with specific collection points planned along the course of the river. Route planning to nearest recycling plants helps save both time and energy in the process.

• River Front Management

  • Developing a river front leads to decrease in pollution of river due to non-point source of pollution and beautification of the river. GIS can help authorities in effective planning of river front such that its development does not affect the biodiversity and ecology of the local flora and fauna.

• Hydrological Modelling

  • GIS can be integrated with a Hydrological model to assess the minimum amount of flow required to sustain the ecology of watershed while allowing the associated industry to run profitably. These models can also be used for predictive planning to delineate the amount of water that would be available throughout the year hence leading to effective river management.

• Pollution Monitoring

  • GIS can be integrated with a Hydrological model to assess the minimum amount of flow required to sustain the ecology of watershed while allowing the associated industry to run profitably. These models can also be used for predictive planning to delineate the amount of water that would be available throughout the year hence leading to effective river management.

• Irrigation Drainage Network

  • Irrigation network operated in the river watershed can be monitored for leakages and problem area can be resolved by using remote sensing techniques. This leads to quick turnaround time and cost effective solution for problems. The demand for water in agriculture can be met keeping the limited water resource available in mind using GIS. Water level in reservoirs can be monitored with sensors and field water requirement can be met using rotation policy by using decision support tools in GIS.

VizExperts is a technology development firm in the realm of Geospatial intelligence driven decision making. We at VizExperts believe in transforming data to decisions through a highly sophisticated and superior visual computing technology. In line with the objectives of Government of India, to accelerate indigenization of technology, our products have all been developed in-house, setting standards of excellence comparable and beyond what is offered elsewhere. VizExperts corporate philosophy is to provide unique and differentiated value to its clients resulting in interactive engagements and mutual partnership opportunities. Our list of clients includes various reputed Indian Government Organizations with whom we have worked on multiple projects using our 3D GIS technology and Digital Sand Model technology. Our R&D teams based out of Gurgaon and Bangalore have some of the best 3D GIS and visual computing talent in the country.

        One of our principal focus areas has been GeorbIS®, our flagship 3D GIS technology, which enables geospatial intelligence driven decision making at organizations functioning in multiple domains. VizExperts GeorbIS has been certified compliant for WMS, WCS, WFS, WFS(T) services by the OGC® (Open Geospatial Consortium), the GeorbIS® platform now offers a unified platform for 3D geospatial data visualization, GIS analysis and multi-data fusion. GeorbIS comes with options for stand-alone desktop based systems and server based enterprise level systems. The platform also offers modular extensions called CartridGIS that offer advanced functionality and customized features, offering out-of-the-box usability. Custom interfaces are included for enabling real-time sensor data integration from the field.

        GeorbIS Enterprise offers a centralized mechanism for collection and dissemination of data and information. It offers integration of distributed data sources and utilizing information made available through different channels. The entire data resides on the server hosted in-house and can be accessed easily through any web browser within the network and through internet. Enterprise solution is based on GIS framework which follows standard three tier architecture with separate user interface, computation and data management layers. It allows publishing of all standard 2D & 3D GIS data formats and multiple non-spatial data formats, viewing, support for data management and offers a high level of security for user and data access. Enterprise solution offers the liberty of visualizing the action plan from anywhere without physical presence as the plans are updated on the map throughout in near real-time. VizExperts offers functionality to customize end solution as its indigenous and well supported and developed by a local technology provider.

        Digital Sand Model solution has been VizExperts oldest and the most sought after product by various defense, police, paramilitary, forest, disaster management, mining, municipal corporations and etc. establishments. DSM is a cutting-edge 3D GIS based solution for operation planning, briefing and training. The DSM technology is powered by the OGC certified GeorbIS® 3D GIS platform for GIS data ingestion. DSM offers true 3D visualization of all terrains including urban, rural, forest, mountainous and desert areas for operation planning. The Digital Sand Model software integrates organization specific workflows for training and operation planning, and includes built-in tools for creating a 3D geodatabase of an organization’s area of interest.

        Intel is a Business Intelligence Cartridge which enables decision making through MIS data by visualization and analysis on a GIS map with the option to generate reports. It allows connecting and merging of spatial and non-spatial databases to fetch data through a single unified database.
