2. Comparative mapping of Deception Island, Antarctica was 
done in order to study topographic changes due to volcanic eruptions 
in 1967, 1969. and 1970. 
3. A systems approach to calibration of the total aerial 
photogrammetric system rather than individual components is being 
pursued through research efforts (Merchant 1974). 
4. Research has been performed on calibration and mathematical 
modelling of the Scanning Electron Microscope (SEM) (Ghosh 1976), and 
panoramic camera systems. 
S. A multi-dimensional (X,Y,Z plus other dimensions like time, 
type of point, color, etc.) mapping procedure is being developed 
through research efforts. This involves a thorough study of the 
various interpolation methods, the development of an acceptable 
optimization technique (in view of the accuracy requirement, frequency 
of points, nature of terrain, etc.) and adaptation of the data to the 
computer and automated plotters. 
Educational Programs 
1. An under-graduate program for B.Sc. degree in Surveying has 
developed with encouraging enrollment under the auspices of the OSU 
departments of Civil Engineering and Geodetic Science. 
2. A new graduate level course "Non-conventional Photogrammetry" 
is being offered. Developed in 1973, this course involyes the geometry 
and quantitative aspects in systems like Strip Photography, Panoramic 
Photography, Ranger and Lunar Orbiter Photography, Landsat, Mariner, 
Electron Microscopy, Holography, etc. 
3. Courses in Photogrammetry and Remote-sensing are offered 
in various disciplines as follows during an academic year: 
In Architecture....... «ee 5 Quarter Hours, repeatable. 
In Civil Engineering........ 16 Quarter Hours per year 
In Geodetic Science.........58 Quarter Hours per year 
Publications 
l. The second edition of book, THEORY OF STEREOPHOTOGRAMMETRY, 
authored by Sanjib K. Ghosh was published by Edwards Brothers, 
Ann Arbor, Mich. in 1972. 
2. A book, PHOTOTRIANGULATION, authored by Sanjib K. Ghosh 
was published by Lexington Books, Lexington, Mass. in 1975.
