We assume that the sensor data along with the map are transmitted to a nearby location perhaps to a vehicle that will be travelling through the area of interest. We would like to use the maximum available information content to generate first a model of the chemical particle distribution, and then locate the source of the particles based on the model. Abstract—This paper addresses the challenge of mapping the paths of particles originating from a chemical source using interpolation and extrapolation methods. Odor localization is the problem of identifying the source of an odor or another volatile chemical in an uncontrolled environment. Most localization methods require following an odor plume along its path by a mobile detector, that is time consuming and difficult in a cluttered environment. In this paper, physically separated multiple sensors and the dynamical behavior of fluids are used to predict the airflow pattern. A model of a particle path using an interpolation and extrapolation method, a framework of the reasoning systems, and results of odor source location process are presented. The method also demonstrates that an interpolation and extrapolation approach can be used to assist the odor localization search and shows that it is successful in reasoning about the surroundings in unstructured environments.
