摘要：Automatic Digital Aerial Triangulation has been implemented at the Institute of Geodesy and Cartography in 1997 on theImageStation 6487 INTERGRAPH. Several blocks of B/W aerial photographs in the scale 1:15 000 taken with RC-10WILD camera and color photographs taken with RC-20 and LMK 1000 cameras in the framework of PHARE LIS Projecthave been adjusted by semi-automatic Digital Aerotriangulation method. The Digital AT has been done as the secondstep (after scanning) of the generation of DTM and orthophotomap digitally.Value of sigma naught (• o) for double diapositives copied from original aerial photographs taken by RC-20 WILDcamera is 8.9 μm. Value of • o for double diapositives taken by LMK-1000 ZEISS Jena is 7.6 μm and 7.9 μm.Standard error in the block adjustment is • o =6.8 μm for the B/W original aerial negatives in the scale 1:15 000.Value of • o=4.1 μm has been achieved for scanned of original aerial photographs of the test block “ECHALLENS”supplied by EPFL, Lausanne.Besides the results of Digital AT, a few examples of the hard copies of the orthophoto maps in the scale of 1:5000elaborated in the framework of the PHARE Project will be presented
