The traditional sampling method for environmental monitoring of aerosols is time consuming and expensive. Remote sensing data have been widely used in environmental studies like land cover change, flood observation, environmental pollution monitoring. This study is dealing with obtaining water pollution using Landsat TM data over Penang Strait, Malaysia.(More)
The use of traditional ship sampling method of for environmental monitoring is time consuming, requires a high survey cost, and exert great efforts. In this study we classify one of the water pollutants which is the Total Suspended Solids (TSS) of polluted water in Penang strait, Malaysia by applying Modified Hopfield Neural Network Algorithm (MHNNA) on(More)
A study was carried out to assess the capability of a personal digital camera to provide useful remotely sensed images for land cover mapping. A Kodak DC290 digital camera was employed to capture images of several test sites. The airborne platform used in this study was a light aircraft, Cessna172Q, flown at an average altitude of 8000 ft above sea level(More)
Environmental monitoring through the method of traditional ship sampling is time consuming and requires a high survey cost. This study uses an empirical model, based on actual water quality of total suspended solids (TSS) measurements from the Penang Strait, Malaysia to predict TSS based on optical properties of (Thailand Earth Observation System) THEOS(More)
Results from the analysis of the retrieved carbon dioxide (CO2) columns in the free troposphere are presented for one year (2005) obtained by the Atmospheric Infrared Sounder (AIRS) included on the EOS Aqua satellite launched on May 4, 2002. Providing information for several greenhouse gases, CO2, CH4, CO and O3 is one goal of the AIRS instrument as well as(More)
In this study, modern ICT and digital technology allow captured images to be transferred over Internet protocol to central monitoring centre. Internet protocol (IP) camera provides remotely and cost effectively monitor system. IP cameras also are flexible, powerful and wide ranging system applications. The objective of this study is to test the feasibility(More)
Air pollution is an important issue being monitored and regulated in industrial and developing cities. In this study, we explored the relationship between particulate matters of size less than 2.5 micron (PM 2.5) derived from the SPOT using regression technique. The aim of this study was to evaluate the high spatial resolution satellite data for air quality(More)
Nowadays application of webcam becomes more and more popular. Thus webcams are being developed to have better resolution but lower cost. This has motivated us to evaluate the suitability of using webcam for indoor air quality monitoring. This monitoring involved determining the concentration of particulate matter with diameter less than 10 micron (PM10). An(More)
