and discussed. 
With impressive precision the satellite camera was aimed at the 
small target area, "S:t Lawrence Bay", and exposure carried out 
by order from the ground station. 
In many of the satellite pictures, it has been possible to identify 
features which are theoretically impossible to resolve with the 
current camera systems. The methods described appeared to be: the 
most promising means for ice analysis and for the development of 
a routine operational satellite ice reconnaissance and surveillance 
program. 
Popham was right, and his judging far-sighted (see below). 
When using special reconnaissance satellites, far better results 
may be expected according to the above-mentioned 1964 report. As 
an example the author pointed to the operational reconnaissance 
satellite SAMOS with photo intelligence equipment by Eastman 
Kodak. Photos were reported to be of the same quality as high- 
altitude aircraft capability. 
The Sovietic equivalent to the American SAMOS the author then 
supposed to be special satellites of the COSMOS type. 
4.5.1 The First Canadian ERTS-Picture 
  
At the XIIth International Congress in Ottawa, July-August, 1972, 
there was a great interest in satellite-carried instruments, and 
the Canadians showed their sincere satisfaction at the fact that 
the first Canadian ERTS-picture (ERTS = Earth Resources Technology 
Satellite) could be demonstrated at this Photogrammetric World 
Congress. It was taken on July 27, 1972, from the US National 
Aeronautics and Space Administration's first satellite of ERTS- 
type, ERTS-1, at an altitude of 920 km. 
The satellite was equipped with two systems for remote sensing, 
1:0 a multispectral scanner, scanning within four different
