The legal amendments for setting the zone to levy the impact fees for infrastructure provision has been made in August, 2008. One of the criteria provided by the law to designate the zone for impact fee requires that the local population increase rate should exceed that of the entire locality by more than twenty percent. Since the population survey by the localities are gathered by the basic administrative units like townships and municipalities, however, it truly renders significant difficulties in accurately figuring out the finite areas that exceed the legal population criteria. This study, in this context, tries to suggest an alternative technique to narrow down the target zone even with such limited population data. For the purpose, the study first tries to join the individual parcel information from the Korea Land Information System (KLIS) and the corresponding building information from the Electronic Architectural System (eAIS) to estimate the number of population in each cell of the 50m by 50m grid system cast over the entire locality. Through the operation of these attribute database on the GIS platform, the grid analysis accurately pinpoints only those cells that exceed the legal criteria on a spatial context. Taking an area located in Hwasung City as the case, the study has successfully shown that the technique could effectively pinpoint the accurate shape of the target zone. |
