OVERVIEW OF THIS APPLICATION

Calculate total emission form fuel consumption

Thailand fuel consumption data are available at Department of Alternative Energy Development and Efficienccy (www.dede.go.th)

ArcGIS software are available at ArcGIS software are available at www.esri.com. In . In this study use ArcGIS v.9.0this study use ArcGIS v.9.0

Thailand digital map (scale 1: 50,000) of Thailand digital map (scale 1: 50,000) of difference provinces is availible at Land difference provinces is availible at Land Development Department website (Development Department website (www.ldd.go.th))
