Using a Dynamic GIS to Visualize and Analyze Mobile Source Emissions

摘要

The paper discusses research that involves implementing a dynamic geographicinformation system (GIS) used in mobile emissions research. In a cooperative research effort with the U.S. EPA, Georgia Tech is currently developing a mobile emissions model that will reside in a GIS environment. The major objective of this model is to more accurately estimate mobile source data. While a brief overview of this model is included, the major emphasis of the paper is using a customized GIS with sophisticated dynamic graphics capabilities to visualize and analyze emission data collected from instrumented vehicles. Each instrumented vehicle in this project is equipped with on-board emission monitoring equipment to record second-by-second emissions and a global positioning system (GPS) receiver that monitors the instantaneous position, speed, and acceleration characteristics of the vehicle.
