Rice Inventory Data Update Procedure Based on Remote Sensedimages: a User Interface Improvement Perspective ̆ˇ

To ensure sufficient and balanced supply of rice production, the Council of Agriculture (COA) must monitor any possible change to the land use and cycle for rice productions. Though COA has been carrying out nation-wide rice inventory procedure in every cropping season for more than 20 years, current COA approach still requires a huge amount of works on photo interpretation, field survey, data edition and statistics report from human operators. By analyzing all procedures required, we proposed an integrated interface concept to effectively reduce required operations and consequently improve the efficiency for creating rice inventory result. The interface allows operators to concentrate on interpretation only and leave all other works to computers. Provided the digital orthophoto can be acquired, the proposed procedure will be much more efficient than the current approach. Though mainly designed for rice inventory data, this mechanism can be applied to all kinds of agricultural crops with a slight modification on the attribute domain values.
