ON THE DEVELOPMENT OF A SUITABLE NUMBER CODING SYSTEM FOR POINTS IN A PHOTOGRAMMETRIC BLOCK

Abstract

In block triangulation one has to deal with a large volume of experimental data involving hundreds of observation points. Relevant information pertaining to each observation point must also be recorded along with image/model eoorciinatm. A code system for photogrammetric points condenses the infor- mation in a small space and is very convenient for reference at all stages of the work, and later. Almost all organizations who deal with block trian. gulation use, of necessity, a code system developed by them-selves. These codes are understandably suitable for particul-ar jobs and lack general applicability. In this thesis an attempt has been made to study the problem in generality and to develop code systems found usable by the majority of orga-r nizationa. Three code systems have been proposed. The number coding system and alpha-numeric system have been proposed for a block covered with spatial aerial triangulation while the alphabetic coding system is meant for block covered by radial triangulation method. The three code systems developed donut present any difficulty in computer programming.
