摘要:In recent decades, photogrammetrists have been exploring the georeferencing approaches that can improve consistency, completeness, and reliability of referenced spatial information. In this paper, an economic feasible georeferencing method is presented. The research data is from Finnish Jabal Haroun Project (FJHP). The primary objectives of the photogrammetric documentation in FJHP have been to provide the archaeological survey group with local topographic maps and the excavation group with 3-D models and drawings. The data are often given in various different coordinate systems because there is no network of control points which existed originally. The differences in coordinate systems have been problematic for archaeological analysis and yielded inaccurate results. It would be important for the archaeologists that all the multi-temporal and multi-scale imagery (multi-image) as well as other data could be integrated into one coordinate system. This paper presents recursive georeferencing method which is performed by using bundle block adjustment in multi-temporal and multi-scale imagery blocks. New points can be obtained from block adjustment of images and can be used as control points in the block adjustment of the next scale. After the implementation of this approach, ten points are derived from different scale imagery– 1:30000 aerial images, 1:15000 aerial images and terrestrial images, respectively. Consequently, coordinate difference is within 2m tolerance. It turns out that the blocks are stable and reliable. As a result, all images are referenced to consistent coordinate system with desired accuracy. Consistency, completeness, and reliability of referenced spatial information are simultaneously improved
