6.2.3.1 Publications
A. Journals. The following journals are special in their presen
tation of analytical concepts and methods in the English language:
1. Photogrammetria: Journal of the ISPRS; four issues per year.
2. Photogrammetric Engineering and Remote Sensing: Journal of the ASPRS;
twelve issues per year.
3. Photogrammetric Record: Journal of the British Society of Photogram-
metry; two issues per year.
4. CISM Journal: Journal of the Canadian Institute of Surveying and
Mapping; four issues, per year.
5. Australian Surveyor: Journal of the Australian Society of Surveyors;
four issues per year.
6. ITC Journal: Journal of the International Institute of Aerospace
Survey and Earth Sciences (ITC); four issues per year.
Certain other national journals in their respective languages deserve
mentioning here, in particular, the Belgian, French, German, Russian and
Swiss.
B. Conference Proceedings: The following conference proceedings are
regularly published:
1. ISPRS Archives: During or following each ISPRS Congress (quadrennial)
or each Inter-Congress ISPRS Commission Symposia.
2. ASPRS Proceedings: During or following each ASPRS Convention (two per
year, Annual and Fall Conventions).
There are also many national and regional international conferences
publishing their proceedings from time to time.
C. Books : Practically all text books and manuals in photogrammetry
contain analytical concepts to a certain degree. However the following
are the only books (in English) specifically devoted to significant con
tents in analytical photogrammetry:
1. Merritt, Everett (1958): Analytical Photogrammetry; Pitman, N.Y.
2. Ghosh, Sanjib K- (1988): Analytical Photogrammetry (2 nd Ed.);
Pergamon Press.
3. ASPRS (1980): Manual of Photogrammetry (4 th Ed.);
(Chester C. Slama, Editor-in-Chief).
Numerous books published in languages other than English are appearing
on the market.
6.2.3.2 Related to Single Images
The theory and mathematical model for central perspective projec
tion being well established through the pioneering prior works of men like
Pulfrich, von Gruber, or Finsterwalder, the basis of Collinearitv Condition
was already there. This condition implies that the object point, the
perspective center (or the exposure station) and the image point must lie
on the same straight line (Ghosh 1988). However, in its application
through the computational procedures there were two problems. Firstly, the
condition equations are non-linear and, secondly, in usual cases more
observations are made than the minimum necessary for unique solutions.
Therefore, to obtain practical and statistically acceptable solutions, it
was found appropriate and convenient (1) to use linearized forms of the
