GIS for Modeling and monitoringEnvironmental pollution


2/11

Major Pollutions

Air pollution

Causes-combustion of fossil fuels,in Automobiles, factories, powerplant Deforestation and use of nuclear weapons.

Effects- Diseases for human being like Asthma,heart

attack,vascular dysfunction. Global warming etc.

Water Pollution

Causes-domestic ,industrial and agricultural wastes, oil spills,marine dumping, radioactive waste.

Effects-unfit for drinking. Waterborne diseases unusable for

agricultural and industrial use

Soil Pollution

Causes-Industrial wastes, agricultural pesticides, fertilizers.

Effects-Decrease in soil fertility and yield. Increase in salinity of thesoil

How GIS helps in Monitoring and

modeling of pollutions

GIS integrates hardware, software, anddata for capturing, managing,

analyzing, and displaying all forms ofgeographically referenced information

GIS allows us to view understand,question, interpret, and visualize

data in many ways in the form ofmaps, globes, reports, and charts

How GIS helps in Monitoring and

modeling of pollutionsEfficient pollutions monitoring and modelingwith Decision Support System (DSS).

GIS can be utilized for

Preparing Environmental Atlas

Mapping of environmental sensitive

zones/ areas

Locating monitoring stations,

Zonal Mapping of pollution,

Mapping of Air and water polluting

Industries .

How GIS helps in Monitoring andmodeling of pollutions

Developing Water Quality

Index(WQI) maps.

Pollution Density Maps.

Spatial geo-positioning of polluters

Tracking the Effects of Pollutants

Analysis Industrial Populations

Management System For Industrial,

Domestic and Municipal Waste

Spatial Data For GIS modelling

Location map of area.

Transport network map(Road network,Type, trafficvolume)

Water bodies of area(river,lake,pond, canal, drainage)

Major Settlement of area(city, town, villages).

Altitude(contour bench mark)

Soil map of area(with soil type,fertility etc)

Industrial maps with their attribute (what they are

using as fuel, what is the waste product)

Location maps of monitoring stations (X,Y

coordinate with their real time data)

Real time Pollution data of Air Water and soil

INPUT GIS Process

Methedology for projects

Selection of Area of Interest (AOI)

Geometric correction of Image of AOI

Digital supervised and unsupervised classification

Ground Survey with GPS Unit for precise ground location

Preparation of digital maps on basis of digital image, GPS data andother Resource

Attach attribute data/tabular information with these maps

Integrate monitoring station data with our spatial maps

Generate output as high polluted, medium polluted and less pollutedarea

Identified buffer zone from central pollution point and analyze theaffected area

Zonal Mapping for Air Quality

Air Quality IndexThe Air Quality Index, or AQI, much like an air quality "thermometer",translates daily air pollution concentrations into a number on a scalebetween 0 and 500. The numbers in this scale are divided into sixcolor-coded ranges, with numbers 0-300 as seen below.

(0-50) GoodNo health impacts are expected when air quality is in this range.

(51-100) ModerateUnusually sensitive people should consider limiting prolongedoutdoor exertion.

(101-150) Unhealthy for Sensitive GroupsActive children and adults, and people with respiratory disease, suchas asthma, should limit outdoor exertion.

(151-200) UnhealthyActive children and adults, and people with respiratory disease, suchas asthma, should avoid prolonged outdoor exertion; everyone else,especially children, should limit prolonged outdoor exertion.

(201-300) Very UnhealthyActive children and adults, and people with respiratory disease, suchas asthma, should avoid all outdoor exertion; everyone else,especially children, should limit outdoor exertion.
