Abstract: To analyze the attribute characteristic and geo-spatial feature of atmospheric Environmental Impact Assessment(EIA), this paper presents a processing method of self-adaptive graphic for visualization of GIS-based point source atmospheric EIA. A self-adaptively grid partition algorithm based on the spreading attribute of the point source atmospheric pollutant, and a new contour, area filling algorithm and proposed. It visualizes and analyzes the result of GIS-based EIA fleetly.
