During the W.G. VII-6 Committee meeting held on Thursday, 16 september, 
attention was drawn to the priority which needs to be accorded to : 
(ij SPOT: 
(ii) SIMULATION MODELS 
(iii) ENVIRONMENTAL STANDARDS 
the technique of monitoring urban environmental structure ; 
the application of, and the tráining of manpower for, these tech- 
niques for urban settlement analysis, and further urban planning 
requirements ; i 
the further development of the application of SPOT imagery to 
Regional Ecological Analysis, including regional, environmental 
mapping ; 
the analysis of the 'dynamics of ecological changes' 
with a quanti- 
fication and economic values attached. 
: with the scale and complexity of environmental degrada- —— 
tion and the erosion of natural resources, and the 
continually increasing demands from an increasing 
number of human beings, more attention should be 
given by W.G. VII-6 to the application of systems 
engineering to environmental monitoring, and modelling 
of the quantitative interaction of ecological environ- 
mental components with the needs of human settlements.

: on the one hand to develop further the use of 
remote sensing for quantifying environmental 
Standards, and on the other hand, to establish 
acceptable standards of the environment which 
can be given statutory support for control 
purposes.
