In the article, several features of the organization of field thematic survey, as well as its value in contemporary environment are studied. They are followed by a brief overview of methods of obtaining of precise quantitative characteristics and organization of survey objects’ monitoring (system of observation control) on special key sites or stationary proving ground; spatial coordination of observation points (satellite positioning, application of GPS-navigators). Necessity of reorganization of field thematic survey is shown on the basis of geo-informational technologies using satellite pictures, the landscape indication method and basic digital maps.
