Abstract Air contaminant density must be inferred exactly to manage
air pollution. Each land use
of r plution source is duplicated in the existing r contaminant
distribution because the resltion of
the land use map is low. The purpose of this study is to understand
how the land use map is used to
deterrnine effectively in the distribution calculation of the
emlSSlon volume and the inference of air
contaminant density, as it is made in a high resolution. The major
findings are as follows In this
study, as to making a high resolution(28.5m X 28.5m) map of land
use with GIS, each r pollution
source is not duplicated spatially and land use can be reflected
effectively. In Seoul, each air
contaminant density was inferred with the existing distribution map
of emission volume, whose resolution
is lkm X lkm, and the new distribution map of emion volume, whose
resolution is 28.5 km X
28.5km. According to the result, the inference value of the new
distribution map was more similar to
the actual value of an automatic survey network. The suitable scale
of resolution was also selected for
the inference of the air contaminant density of Seω1 using a TCM-2
model.
