suit the project in hand. This DSR15/KRISS-LITES2 interface has 
been very well received by Ordnance Survey in England, the bulk of 
whose work is now map revision rather than new mapping. 
This product range is completed by a number of instruments which 
have been on the market for many years and require no further 
description here: the Wild 0R1 orthophoto projector; the Wild 
PUG5 and Kern PMG2, CPM1 and CPM1+ point marking and transfer 
devices and comparators; and the Kern GP1 plotting table.

Also manufactured in Aarau, as explained in sections 1 and 2 
above, are the ECDS and SPACE systems for industrial measurement. 
ECDS makes use of industrial versions of the E2 electronic 
theodolite, whereas SPACE uses a version in which the telescope is 
replaced by a CCD array. Whether these systems are 
photogrammetric is a nice point for debate, but SPACE has 
certainly been described by some workers as a system for close 
range photogrammetry. Special measurement systems are also 
manufactured to order, some of which use CCD cameras and bundle 
adjustment but fall within the purview of ISPRS Commission V.
