In the context of urban planning, it is very important to estimate the nature of the roof of every building and, in particular, to make the difference between flat roofs and gable ones. This analysis is necessary in seismically active areas. Also in the assessment of renewable energy projects such solar energy, the shape of roofs must be accurately retrieved. In order to perform this task automatically on a large scale, aerial photos provide a useful solution. The goal of this research project is the development o...

The article shows the new methodical approaches to evaluation of planning quality and realization of technological water use process as for irrigation systems as a whole, as for separate irrigated plots on agricultural premises and on farms. There were based and developed: a new classification of irrigation systems, a new method of standard calcu-lation and possible limits of change in technical, ecological and economic values at wa-ter use on irrigation systems. There was proposed a system of technical and econom...

This study reviews the problem of creating an algorithm for classifying objects in a Grid system, which will allow the automation of this process to proceed. Splitting objects into classes allows you to effectively manage the resources and processes that occur in a distributed system. Classification according to the current values of characteristics, by reference values of characteristics, with an analysis of the original causes of the result and also a modeled classification is considered. The problem of determin...
