Professor Eduard Doležal was born in Budwitz, Moravia, in 1862. In 1876 his family moved to Vienna and he chose teacher's education for his studies. He became a teacher at the Secondary Technical School in Sarajewo in 1889. Eventually, on 1 October 1905 he was offered a position as Ordinary Public Professor of Practical Geometry at the Vienna University of Technology and was elected president of the university only three years later. On 4 July 1910 Professor Doležal founded the International Society for Photogrammetry and organized the first International Congress for Photogrammetry held in Vienna on 24-26 September 1913. From 1908-1923 he was editor of the International Archives of Photogrammetry. Showered with honors, he died on 7th July 1955.

47-55 Automatic Relative Orientation of Aerial Images
Tang Liang and Christian Heipke

Relative orientation of two aerial images is cast into an operational automatic procedure which runs faster than a human operator can measure conjugate points and yields the same level of accuracy.

57-66 A Recursive Approach to Space Resection Using Straight Line
Antonio Maria Garcia Tommaselli and Clsio Luis Tozzi

A recursive procedure using Kalman Filtering and straight lines is proposed in order to solve the space resection problem.

67-72 Precision Rectification of SPOT Imagery Using the Direct Linear Transformation Model
Yasser El-Manadili and Kurt Novak

After correcting for distortions caused by Earth rotation and off-nadir viewing, sub-pixel accuracy can be achieved with as few as six control points.

73-77 Relative Accuracy of Rectifications Using Coordinates Determined from Maps and the Global Positioning System
Allen E. Cook and John E. Pinder III

A comparison of the accuracy of 1:24,000-scale USGS maps and code phase GPS receivers for measuring the UTM coordinates of ground control points indicated that the greater accuracy of GPS significantly affected the rectification of Thematic Mapper and SPOT data.

79-83 Initial Approximations for the Three-Dimensional Conformal Coordinate Transformation
Bon A. Dewitt

The method enables accurate determination of initial approximations for all parameters, thus ensuring convergence of the iterative solution.

85-88 Design and Implementation of a Photogrammetric Geo-Calculator in a Windows Environment
Rongxing Li

Geometric entities such as coordinates, distances, differences of elevation, azimuths, areas, and profiles can be calculated through the measurement of objects appearing in stereo images.

89-92 A Photogrammetric Simulator for Close-Range Applications
Tian-Yuan Shih

The simulator, intended for project design utilizing hand-held cameras, has been implemented on a CAD system.

93-99 Shape Reconstruction from Multiple Images of the Ocean Surface
Howard Schultz

To analyze the fine scale structure of the ocean surface, a new technique (known as Specular Surface Stereo) is proposed that makes use of the unique optical properties of water.
