TECHNOLOGICAL OPTIONS FOR
SUCCESSFUL POLLUTION CONTROL
PROGRAMS USING
REMOTE SENSING, GPS, GIS AND
OTHER GEOSPATIAL AND SENSING
TECHNOLOGIES
The utilization of various geospatial technologies has
been instrumental to advance the understanding of
environmental factors affecting human health and well-
being.
Extreme weather and related phenomena appear to be
rising in frequency and intensity which pose growing
risks to human populations and the environment.
Earth observing technologies and data are important
elements of a comprehensive and multi-scaled public
health response both at micro and macro levels
identifying immediate and long-term impacts.
Remote sensing and geospatial technologies have been
successfully implemented over the last 50 years
examining the role of environmental factors in air-borne,
vector-borne, soil-borne and water-borne diseases.

FIELDS OF APPLICATIONS OF VARIOUS
GEOSPATIAL AND SENSING
TECHNOLOGIES
•Air, soil and water pollution modeling for health and
environment impact studies
•Study of air-borne, soil-borne and water-borne diseases
•Data analysis in public health research
•Environmental public health surveillance
•Infectious and vector-borne diseases
•Climate variability and health
•Tele-epidemiology
•Surveillance and monitoring of environment

REMOTE SENSING (RS)
Remote sensing (RS) is the process of detecting and
monitoring the physical characteristics of an area by
measuring its reflected and emitted radiation at a distance
(typically from satellite or aircraft).
Some specific uses of remotely sensed images of the Earth
include:
•Environmental pollutions like air, soil and water
pollutions.
•Large forest fires can be mapped from space.
•Tracking clouds to help predict the weather.
•Watching erupting volcanoes, and help watching for
dust storms.
•Tracking the growth of a city and changes in farmland
or forests over several years or decades.
•Discovery and mapping of the rugged topography of
the ocean floor.

GEOGRAPHICAL INFORMATION SYSTEM
(GIS) Geographic information system (GIS) store, analyze, and
visualize data for geographic positions on Earth’s surface.
It is a computer-based tool that examines spatial
relationships, patterns, and trends in geography.
Some specific uses of GIS include:
•Pinpointing various pollution locations
•Zonation of contamination areas
•Mapping and predicting air, soil and water
cobtaminations
•Forecasting and predicting weather
•Routing in car navigation

6. 6
GLOBAL POSITIONING SYSTEM (GPS) Global positioning system (GPS) is a global navigation system using
satellites, a receiver and algorithms to synchronize location, velocity
and time data for air, sea and land travel.
The 3 segments of GPS are:
•Space (Satellites) — The satellites circling the Earth,
transmitting signals to users on geographical position and time
of day.
•Ground control — The Control Segment is made up of Earth-
based monitor stations, master control stations and ground
antenna.
•User equipment — GPS receivers and transmitters including
items like watches, smartphones and telematic devices.
Some specific uses GPS include:
•Location — Determining a position.
•Navigation — Getting from one location to another.
•Tracking — Monitoring object or personal movement.
•Mapping — Creating maps of the world.
•Timing — Making it possible to take precise time
measurements.
