(Data 
Reduction) 
(a) It is impossible to combine the requirements for high spectral, high spatial and high temporal 
resolution into one satellite system. Therefore several systems must be used to integrate satel- 
lite information in an optimal manner. 
(b) In platform use we depend highly on existing and future advances and failures of launcher 
technology. 
(c) In data reception there is again a technological risk and an optimal choice to be made between 
manned systems, unmanned systems from which data are received by many ground stations 
in various parts of the globe, and between systems like TDRSS which permit global coverage 
passing information directly through a network of satellites to the United States. 
(d) A fourth aspect is the recent commercialization of remote sensing satellite technology started 
by the Landsat Commercialization Act in the U.S. A. 
This step will no doubt make remote sensing more expensive than it has been in the past.
