In this year,base on the previous year results, we will continue to apply remote sensing techniques to monitoring illegal fallow fields and try to combine airborne SAR image data, generated by Aerial Survey Office, and optical remote sensing data to interpret rice crop and fallow field crops. The improvements of this year, in optical satellite image part, we will use 4 pair of image data from rice transplantation to harvesting to understand more detail about the spectrum change of crops in fallow fields. In monitoring target part, except obviously illegal fallow fields, we will focus upon illegal fallow fields with garlic. This project will integrate garlic monitoring and reexamine mechanism, compare garlic crop data between generated by township office and monitoring by remote sensing interpretation with ground survey to reexamine the data accuracy and analyze the spectrum feature of illegal fallow fields with garlic. In smart farmland unit detection model part, we will apply pixelbased and regional-based data transfer feature vector analysis to improve the accuracy of farmland unit detection. With integrating optical and SAR image data in rice crop and fallow field crops interpretation, illegal fallow fields with garlic spectrum feature analysis and interpretation, establish garlic crop monitoring and reexamine mechanism, smart farmland unit detection model in this project, we can continuing developing remote sensing interpretation techniques of crops and integrating crops reexamine mechanism to help Agriculture and Food Agency (AFA) monitor farmland more efficient and reliable.影像分割影像分類影像單元化知識庫管理農田耕作狀態轉移偵測休耕田遙測技術機載合成孔徑雷達系統Image SegmentationImage ClassificationImage UnitKnowlage Databased ManagementFarmland cultivation state transition detectionFallow應用高解析度光學衛星及機載雷達遙測影像進行農作物生產調查與複查機制
