The last thirty years of environment monitoring witnessed a rapid development of the active remote sensing technology. Therefore, it is appropriate to consider this period as an advent of the active remote sensing. This paper offers a quick outline of the basics terms, approaches and typical applications of the technology which includes radar, synthetic aperture radar, synthetic aperture radar interferometry and methods which are derived from the synthetic aperture radar interferometry including the differential synthetic aperture radar interferometry and permanent scatterers. The polarimetric synthetic aperture radar interferometry and LiDAR were omitted from this review.

The integration of grounds is one of basic concepts of farming devices, formative the optimum-structure of the agricultural space. A main objective of farming devices is the improvement of conditions of the farming in the country. The correct execution of integration works demands reliable and objective execution of the grounds assessment. On the job one proposed the utilization to qualifying of the value of the respect of the comparative ground the comparative approach, with the utilization of marketable prices of agricultural real property in the area of embraced integration conduct. One applied for the realization of put aim one of methods of the statistical analysis of the market. In proposed model of the multidimensional comparative analysis were taken into account guilds market differentiating prices transactional agricultural real property.

Cadastre should function in accordance with the low and should also meet the requirements of the system environment in area of the realization of tasks connected with the demand for cadastral data of their both individual users and business. The results of the carried out analysis of the rures, backgrounds and the reasons for the cadastre’s function, in comparison with the theory of the system’s work effectiveness and the eules of the rational management show, that in the description of cadastral system the efficiency, as the one of the system’s descriptors, could be considered. In general, the sys- tem’s efficiency should describe its effectivenss and cost-effectiveness. Taking the state of the research on the effectiveness of the cadastre function into consideration, there is need to work out the method of the evaluation of the system’s efficiency in defined time and place. That situation requires undertaking sequrence of research tasks, above all defining the set the diagnostic features, which state decide on the way of collecting, accessing, improving and describe the quality of the potential of the functional value gathered in the system.
