Accuracy aspects of bundle adjustment application of cadastre and network densification.

Due to the successful compensation of systematic image erros by self-calibrating bundle adjustment, photogrammetric point determination has reached an accuracy level which opens new fields of application. Based on empirical accuracy studies of three different test blocks (Jamijarvi, Willunga, Kapunda), this paper shows that an accuracy expectation of photogrammatically determined coordinates of mu.x, y 2.5 micrometre in planimetry and mu.z = 4.5 micrometre in height is realistic, if farily densce control is used. Hence, analytical photogrammetry becomes an interesting tool for point determination purposes in cadastre, land consolidation and network densification. A further investigation is performed with respect to the applicability of modern analytical plotters to such problems. It is demonstrated, that the loss of accuracy is only about 10-20%, if Zeiss PLANICOMP C 100 data are used instead of PSK I data. -Authors
