GIS APPLICATIONS IN AIR MONITORING
[attachment=16846]
INTRODUCTION:
Air pollution has significant effects on public health. It is believed to be responsible for many respiratory andcardiovascular diseases. So it is necessary to implement legislations to protect public health from adverse effects of pollution. However,proper policies can be set only when the pollution change trends are correctly monitored and adequately understood.
GIS IN AIR QUALITY MANAGEMENT:
By doing air quality modeling in a GIS environment, the output of the pollutant records can be obtained in the form of spatial records. GIS science and technology is capable of supporting the development of geospatial air quality models. For modeling in GIS environment, AQMS may consider as be thought of comprising three phases namely, monitoring, development of DSS and execution.
TEMPORAL GIS:
We live in a dynamic world. Every thing around us changes at different rates. Most of the phenomena change over time so spatio-temporal GIS have been developed. Traditional GIS applications deal with sets of static objects, many spatial referenced objects change with time and more and more applications referred to location and time are considered;
METHODOLOGY:
Internet GIS is a relationship between GIS and Internet. Users will be able to access GIS applications without purchasing GIS software by using a web browser. Detailed maps can be generated from huge databases of spatial information and distributed all over the world.
. CONCLUSION:
The air pollution problem originating from the various sources can be controlled by the development of air quality management system. The seasonal air pollution surfaces are useful for wide range of purposes: for health risk assessment of the population within the study area, to assist in establishing and monitoring air quality standards, and to evaluate transport policies.
