摘要: | 林務局農林航空測量所自1956年成立至今,為全國唯一之航遙測專責機構,除協助政府進行過三次森林資源調查外,所轄眾多業務中尚包含航空攝影,至今累積數量龐大之航攝資料,包含全台灣地區逾70萬張航攝底片。另為因應數值業務需要,自2001年起開始進行數位掃瞄工作,至2004年底完成約28萬幅航攝數位影像。
航攝資料可取代大量實地調查,獲取資料可作為土地利用調查、變遷分析等進一步分析的基礎。因航攝資料數量龐大,在查詢應用上亦不方便,須建立一完整之航攝數位影像管理系統,藉助詮釋資料促進航攝資料的管理及流通共享,有其必要性。 本研究整合大型儲存設備及網路架構,並利用詮釋資料提供查詢,應用現有電腦及網路技術,建立航攝數位影像管理系統,以應管理及應用之需。 研究結果顯示,航攝數位影像管理系統可減少管理流程及人力,並提升航攝資料的查詢應用速度,達到航攝資料的流通共享目的。 The Aerial Survey Office of the Forestry Bureau, Council of Agriculture established in 1956 which is the only relevant agency in Taiwan. It has engaged extensive survey of forest resources for three times. Aerial photography is one of its major services which has already collected over seven hundreds thousands films of image data over the whole Taiwan areas. Since 2001, this office started scanning and digitalizing its treasures. It was estimated that this office will produce over 280,000 digital images in the end of 2004. Aerial photograph is alternative of comprehensive on-site survey which can collect more data on land use and engage further analysis of transition with less manpower. However, due to the vast amount of information of aerial photography, there is a need to develop a holistic database management system for digital imagines derived from aerial photographs. Metadata can play a key role within this management system which will enhance management effectiveness, circulating and exchange of information. Integrating with large memory equipments and an internet framework, this study tried to adopt metadata as the basis of searching service and to apply computer and internet techniques in order to develop a management system of digital aerial images. The result shows that the management system can shorten the management processes, reduce labor cost, and improve searching efficiency. This has made considerable contributions to distribution and sharing of aerial information. |
