The purpose of this study is to investigate on tideland reclamation projects as a part of situation on farm land improvement measures in north korea. By using satellite image data beyond the national boundaries, it makes possible to analyze tideland reclamation projects, and owing to the developed software and procedure we can analyze data regardless of difference in data acquisition date. Satellite image data LANDSA T TM and JERS-l data are mainly used, and analysing software ER Mapper, ERDAS, IDRISI are used. Reclamation survey result made by the ministry of unification in 1994 were examined by means of remote sensing using satellite image data. The results are ; Completed and/or partly completed project are 24,596ha and planned are about 142,223ha, 166,819ha in total. However, they already reported about 300 thousand ha would be reclaimed from the sea in early 1980.
