INSTRUMENT SYSTEMS FÜR ULTRA WIDE ANGLE MAPPING 
By Donald Kennedy, 
Wild Heerbrugg Ltd. 
Introduction 
At the 196G Congress of the International Society for Photo- 
grammetry in London, the first complete instrumentation for 
mapping from ultra uide angle (120°) photography uas introduced 
to the public by Wild Heerbrugg. The development of this instru 
mentation up to 196G has already been described in the published 
technical papers (l) (2) (3) (4) (5) (6) (7). The instruments 
had been designed in tuo groups as integrated instrument systems 
catering fully for mapping based on photogrammetric control de 
rived by analog and by analytical methods. 
Briefly, the basic instruments in the Wild ultra uide angle pro 
gramme are as follous: 
- for photography, the RC9 Camera 
- for diapositive printing and correction, one of the U3 or U4 
Printers 
- for analog triangulation and subsequent compilation, the A9 
Autograph and the B9 Aviograph, both using reduced diapositives 
- for analytical triangulation and subsequent compilation, the 
STK1 Btereocomparator and the B8 Aviograph, both accepting 
full-size diapositives. 
In addition, Wild manufacture several auxiliary .instruments for 
use uith the basic ultra uide angle equipment; tuo neu air 
borne instruments have been developed since 196G and many impro 
vements have been made to the original products in the course 
of normal development. 
In vieu of the neu equipment and the modifications made to 
existing instruments since 196B, a list of the current Wild 
airborne equipment for ultra uide angle mapping is given,
