The purpose of this study is to develop cultivated field estimation system of agricultural district for effective water management. We found some errors when we estimated cultivated field area in SI-GUN unit by using cultivated field estimation model(Chang, 2008). Those were some surplus of structure and local allocation effects. To solving these problems, we adopted damping constant to structure and local allocation effects. KREI-ASMO model estimates the cultivated field area in DO unit with parameters calculated in numerical minimization of standard deviation errors. cultivated field estimation model estimate cultivated area of SI-GUN unit with damping constant. Finally, cultivated field area of agricultural district was calculated with area ratio of related SI-GUN. For improving convenience, computer program and user interface were programmed with visual basic 2005. Result of developed program show the same estimation of the modified model. |
