Among the various tasks, control data, including 1-D, 2-D, and 3-D control points for network adjustment or photogrammetric aerial triangulation, control points for image registrations or geometric rectification, and control terrain(surface) for ortho-photo (true ortho-photo) generation are essentially needed. The preparation for the above data may be labor-intensive and costly. Recently the increasing demand of geo-spatial data in civil and national scale is significant, mapping product combined with Geographic Information Systems provide an efficient platform for managing digital images, digital maps, digital terrain models, and other vectorized or rasterized spatial data, consequently offering an ideal database for extracting geo-spatially significant information, such as the afore-mentioned control data. The concept of “Control Entity Database” aims at collecting in the database the features along the production line or via digitalizing and extracting what are needed in the existing maps. For full employment of these data, control entities should be well organized, informative, and accurate so that they are able to be managed and processed in an automatic as well as highly efficient way. In order for that, the attributes of control entities are featured by geometric and radiometric contents, and the derived information. The constitution of control entities database in army mapping agency is then crucial for reducing the labor work and promoting the geo-spatial data process towards the goal of automation. We propose in this study for investigating into the concepts of employing control entities, managing the database, and exploiting the significance of control entities on their related applications. The near goal of this research is aimed at possessing the efficiency in extracting control data for orientation and map revision purposes while with the long-term ultimate for geo-spatial data management and geo-spatial data mining.空間資料特徵資料匹配修測自動化Spatial dataFeature dataMatchingRevisionAutomation
