Classification of Korean Export Gateways based on Geovisual Analytics

The purposes of this study are to analyse the transformation of Korean export gateways between 1991 and 2010 and to categorize them according to its attribute type. The analytical cycle is every 5 years(1991, 1995, 2000, 2005, 2010) during last 2 decades and the subjects of analysis are 25 trade gateways(21 seaports and 4 airports) in Korea. This study has developed 7 models to analyse gateways's category based on 5 indexes(amount of export, export freight weight, export freight value, number of export countries, export item numbers). These models using geovisual analysis could categorize 25 Korean export gateways into 5~6 types. The outcome of this study gives us a good understanding of Korean trade gateway system and will help many gateway's operators to establish their own developing strategies corresponding to it's attribute type.
