  • GIS technology is a modern assistant in the selection of real estate

    The authors propose to consider an interesting solution for finding real estate using GIS - technologies. This method can significantly reduce the time it takes to select a property. This article shows how the data processing capabilities of scientific computing tools for Python and the visualization and analysis capabilities of ArcGIS geospatial data can be used to build a model that generates a short list of houses that meet the needs and desires of potential buyers. And although the choice of a house is purely individual, there are a lot of common factors. Such as the total area, the number of floors and rooms, the presence of a garage and much more. Also, when buying a house, you are looking for proximity to services such as food, pharmacies, emergency rooms, child care facilities, parks, etc. You can use the ArcGIS API geocoding module for Python to search for such objects at a given distance around the house. This method suggests combining all the necessary conditions into one system, which will significantly reduce the list of real estate objects on the market and choose the most optimal options.

    Keywords: GIS, ArcGIS, real estate, Python, maps, histograms, filter, DataFrame, spatial distribution, geocoding

  • Problems of implementation of regional capital repair programs (on the example of the Rostov region)

    Improving the quality characteristics of the operated housing stock, today, is one of the urgent tasks. The mechanism for solving this problem is the ongoing regional capital repair programs. The basis of an effective capital repair program should be reliable data on the actual technical condition of the facilities, allowing you to determine the required list of types of work, as well as the cost. However, despite significant results, a number of problems have been identified. The article highlights the technical and strategic problems of implementing capital repair programs, and defines the features of performing repair work on cultural heritage sites. This information will allow us to create programs that take into account not only the specifics and degree of deterioration of the region's housing stock, but also to create a system of resource provision for the medium term, assuming the achievement of the target values.

  • Experience in using electrical exploration methods to assess the environmental safety of wind power plant construction in the Eastern Donba

    The article presents the results of complex geophysical studies to assess the environmental safety of the construction of wind power tower installations in order to prevent their design and construction in technogenic and tectonically disturbed zones on the territories of mountain branches of closed mines in the Eastern Donbass. The brief essence of electrical exploration technologies of electroprospecting method by electrical spatial filtering (MPEF) and electro-potential tomographic sensing (EPTS). The information content of the technologies used in conjunction with standard geophysical methods of electrical exploration (vertical electric sounding and seismic survey method of refracted waves) is shown. The results of interpretation of data obtained in the field are discussed. The results of the research were: - identification of EPTS technologies of structural inhomogeneities of the geological section of coal-bearing deposits with their division into lithological (repetition of the form on the electric profiling graphs shifted by the step of the feed line transfer) and tectonic or technogenic ones (difference electric probe curves at adjacent points) - detailing of destructive zones identified by EPTS using MPEF technology: 1) inversions of electro-profiling graphs registered with multidirectional electric field excitation. 2) displacement of inversion points in places where tectonic discontinuities are present in the coal-bearing column.
