Data of aero/space surveys are widely used in our 
country for prospecting and utilization of natural re 
sources, geological mapping, exploration of mineral re 
sources and environmental protection. Three interconnec 
ted and interdependent directions of aero/space investi 
gations appear the most promising: development of theore 
tical and physical foundations for remotely-controlled 
sounding, development and improvement of hardware for 
collection and processing of aero/space information, de 
velopment of methods (technologies) for interpretation 
of the above information for practical purposes. 
Modem technologies are based on recording by pho 
tographical, optoelectronic multispectral (within 0.4 - 
20 range) and radar devices of amplitude, frequency 
and geometrical parameters of electromagnetic self-ra 
diation and back-scattered radiation from natural objects; 
they are also based on integrated processing of the re 
corded parameters with the use of digital and analog 
computing systems. 
'The efficiency of aero/space technologies can be 
enhanced by additional recordingof phase, polarization 
and luminescence parameters of back-scattered electro 
magnetic radiation, also of second-order interaction 
terms for various physical fields. The technologies can 
be improved by optimization of employed parameters cha 
racterizing the properties of natural objects, as well as 
methods for processing of the aoove parameters. 
The M Aerogeologia” association and VrAT IK AM institute 
nave developed efficient technologies for geological and 
nature-protection purposes. These technologies can be 
lisenced out as sets of documentation, or contracts can 
be concluded for particular missions and for training 
of specialists.
