Foundation And Application Of GCP Database

Ground control point data is essential datum for geometry processing in the remote sensing .It expense much time in inquiring control point and use manual method to select the same point which influences the precision on the man's techniques level and man's eye by the classic method to have control points. It influence mass quality and efficiency of remote sensing's industrialization on different level to procure data, manage result and share communion partakepool.by the remote sensing's development, The paper introduce the model of database creating, managing. The management of data of the grouping usually adopts the way of system or database and method of image matching. Accordingly the proposed the scheme that the signed and use of access database and VB language and realized an experimental system of the image control point management and appellations .In order to improve the matching speed, make use of pyramid image method. By the analysis thinks, building up control point portrait a database is the valid path which makes use of a control point resources again. According to that is can avoid the long cycle, low efficiency of application and re-use. The foundations of map and image database is the base of rectifying with high efficient and accuracy.
