However, analytical stereoplotters are quite expensive, they require a certain space, and there can only be one operator working at the same time. Normally, a university or institute does not have access to more than a few analytical stereoplotters, while the students may be numerous - especially in the earlier courses. The Department of Geodesy and Photogrammetry at the Royal Institute of Technology, Stockholm, Sweden, has developed an educational aid in this field, called PC-TAS (PC-Tooled Analytical Stereo-modelling). PC-TAS is a concept which uses simple hardware and software available at almost any university: A cheap digitising table and an ordinary PC with MS Windows, MS Excel 5.0 (or higher) and Software Wedge (a TAL Enterprises software for linking the digitising table output to the Excel sheet. Similar softwares may be equally good to serve this linking purpose). However, the real tool in the PC-TAS concept is the 350 kb Excel sheet where all input, calculations and output are done. With this relatively simple and inexpensive equipment the students can sit down at the PCs and explore the basic principles of analytical photogrammetry in their own pace and with their own hands. The number of exercises on the analytical stereoplotter can be reduced drastically (normally there are more PCs and digitising tables available than there are stereoplotters). In addition, the PC-TAS Excel sheet is designed for beginners and is easy to use with its different colour codes indicating where to digitise and where to look for different kinds of results. 1. THE DEVELOPMENT OF PC-TAS the time for program development was sparse and it would be easier to use an existing software than to develop a new one. Another important factor was that the students were already familiar with this software from Faced with the fact that 100 students were to be given a other applications. It is also an advantage that it is fairly basic course in photogrammetry, the Department of easy to get an overview of the calculations on an Excel Geodesy and Photogrammetry at the Royal Institute of — sheet, to see how the equations are built up and to trace Technology realised that a single analytical stereoplotter the dependants of a variable. would not be sufficient for their needs. The thought of developing an easy-to-use analytical software for educational purposes arose. It should be noted that the idea of using a digitising table 2.1 Hardware requirements together with some software for analytical photo- grammetry is not new - there have been commercial PC-TAS uses an ordinary PC capable of running MS Systems available since 1983 at the very least.

THE PARTS OF PC-TAS Apart from the PC-TAS 350 kb Excel sheet, you will need MS Windows 3.1 (or higher versions), MS Excel 5.0 (or higher) and some software to analyse and link the There were several reasons behind the decision to use digitising table output data to MS Excel.
