The article is devoted to the research of approaches for monitoring the condition of land plots both occupied by MSW landfills and the ones negatively influenced by the neighboring landfills. The con-cept of a landfill of solid municipal waste (MSW) is considered. The characteristics of the negative environmental impact of municipal solid waste landfills on the state of land resources are given. Geo-analysis and geomodeling methods have been applied to plan the placement of municipal solid waste landfills, as well as to predict their negative impact. Examples of the placement of municipal solid waste landfills near settlements, as well as examples of the choice of land plots for the construction of landfills are considered. The list of optimality criteria that are used when choosing a land plot for the placement of a landfill is shown. A technological scheme of work has been compiled to determine the level and area of contamination of land plots by landfills of solid municipal waste. The stages of work are closely considered, which include: cadastral and geodetic works, as well as environmental monitoring of the state of land resources. The values of the mean square error of determining (predicting) the coordinates of the boundaries of contaminated land plots are proposed, depending on the category of land, the location of the landfill, as well as the speed of pollution propagation. The characteristics of different rates of pollution propagation, which is formed as a result of leachate ingress beyond the boundary of protective engineering structures, are given. The periodicity with which it is necessary to carry out monitoring measurements of the land pollution level is justified. The methods of coordinating the boundaries of pollution, as well as various measurement tools, are considered. The discussion touched the questions connected with waste recycling technologies and positive impact of refusal of storing SMW both on ecological state of resources and their investment and market appeal. In conclusion, it is stated that the modern concept of sustainable development of territories should be based on environmentally safe land use, the principles of which criticize the creation and operation of landfills of solid municipal waste. Existing municipal solid waste landfills should be operated using land information modeling technology, which should be based on a geoinformation model of the prospective development of the territory. This model includes the dynamics of changes in the number of residents within the boundaries of territorial entities served by a landfill of municipal solid waste.

When carrying out emergency recovery work to eliminate the consequences of an emergency, it is necessary to promptly provide information on the state of transport infrastructure facilities, which is possible only when using aerospace survey data. The aim of the study is to increase the efficiency of transportation in the emergency zone using heterogeneous vehicles under the conditions of synchronization of its movement, based on the use of Earth remote sensing data. Data source analysis for traffic flow modeling was carried out. Land transportation typical network graph description is presented. The dependences of the intensity of traffic flows along the edges of the network graph on traffic conditions, infrastructure characteristics and loading and unloading operations, parameters of wheeled, tracked vehicles and railway cars are revealed. It is proposed to use the minimax criterion when calculating the maximum traffic flow intensity along the network graph path and the entire transport network capacity. Based on the analysis of the tasks of monitoring the state of transport infrastructure facilities, the possibility of using Earth remote sensing data to reveal damage and flooding in the emergency zone was assessed. Based on the simulation modeling results of the ground transportation organization in the area of emergency response based on the Earth remote sens-ing data, the applicability of the proposed approach to the traffic flows intensity calculating based on the Earth remote sensing data was confirmed.

The paper analyzes some causes of distortion of the set and measured vibration parameters during testing of equipment on an electrodynamic vibration stage. In particular, the influence of the joints of the mating surfaces on the vibration stand – a transition table and a transition table – a device for vibration is determined. An idealized model of the junction of two surfaces is proposed, which can be theoreti-cally described using the theory of generalized conductivity of heterogeneous structures. The joint is represented as a matrix of metal with inclusions of voids, represented as components of a mixture having infinite conductivity. A relation is derived showing that the elasticity model of the two metal surfaces joint is approximately 30 % less than that of a homogeneous metal. The obtained theoretical conclusions substantiate the recommendation to increase the rigidity of the mechanical system "vibration stand table - transition table – device for vibration tests" by introducing a thin (40...80 microns) polyethylene film into the joints. The fundamental reason for the difference in the measurement of the vibration acceleration magnitude at different control points is shown – the presence of a tipping moment in the mechanical system. Elimination of a methodological error during vibration tests is possible when controlling the vibration stand not by a real, but by a conditional control point. Recommendations on the choice of a conditional control point for the vibration stand during vibration tests of the equipment are given and justified.

A technique has been developed that allows determining the volume of water resources of hydro-graphic objects using materials from remote sensing of the Earth and a digital terrain model (DEM) of the terrain. The task is relevant, especially in conditions of inaccessibility or difficult approaches to the object. The technique includes the use or construction of a DEM of the bottom of a water body according to bathymetric survey data, the transformation of satellite images into a projection most corresponding to the Earth's surface at these latitudes, the definition of the contour of the shoreline of the reservoir and the calculation of the volume of water. For the purpose of testing, a shallow-water object was selected on the territory of Russia, for which seasonal fluctuations in the water level lead to significant changes in resources. The results revealed a good convergence of the proposed approaches with the accumulated materials of traditional bathymetric survey.

Terrestrial laser scanning of industrial facilities has a number of features, among which are: a large number of laser scanner installation stations, short distances between stations, complex geometry and differences in the reflectivity of the measurement objects materials, as well as a large amount of data derived from the work. To achieve the required accuracy in solving different tasks these features must be taken into account when performing measurements, as well as when processing measurement results. Based on the analysis early research and practical experience, authors propose a generalized technological scheme for terrestrial laser scanning of industrial facilities. In the article the scan settings also calculated, including setting of scan resolution, the choice of the distance to the object and the permissible beam incidence angle. Proposals are also given for the point cloud registration and datum transformation using an Iterative Closest Point Algorithm. The performed studies can be useful for precalculating the accuracy of the terrestrial laser scanning results.

A technique was developed for generating digital models of geoid heights for reference coordinate systems using the Trimble Bussines Center software (TBC software). The source models can be the publicly available high-precision global geoid elevation models EGM2008, EIGEN6C4 and other models whose files with the *.ggf extension are compatible with the TBC software. The technique is based on the possibility of exporting orthometric heights from the TBC software in ASCII format to a user-specified area on the surface of the global WGS-84 ellipsoid for a uniform grid of nodes in lati-tude and longitude. The resulting data table is the starting point for calculating geoid heights for reference coordinate systems, which are determined by the parameters of the corresponding reference ellipsoids and Helmert parameters - spatial position, orientation and linear scale relative to the global coordinate system, according to Standard. The initial data are sufficient to calculate the digital model of the geoid heights for an arbitrary reference coordinate system. The expediency of the developed technique lies in the possibility of its use for a much more accurate calculation of the Helmert parameters for regional and other territories compared to the accepted standard values and, accordingly, a more accurate transformation of the three-dimensional positions of points between the general earth and reference coordinate systems (these issues will be discussed in a subsequent publication by the author). Approbation of the technique was carried out for several regional territories: Novosibirsk and Moscow regions, the territory of Western Siberia, the Republic of Belarus in the SK42 and SK95 coordinate systems, and the results are presented graphically in the form of geoid height maps.
开发了一种利用Trimble business Center软件(TBC软件)为参考坐标系生成大地水准面高度数字模型的技术。源模型可以是公开的高精度全球大地水准面高程模型EGM2008、EIGEN6C4和其他文件带有*的模型。ggf扩展与TBC软件兼容。该技术基于以ASCII格式从TBC软件导出正交高度到全球WGS-84椭球表面上用户指定区域的可能性，用于纬度和经度节点的统一网格。由此产生的数据表是计算参考坐标系的大地水准面高度的起点，根据标准，它由相应参考椭球的参数和赫尔默特参数——相对于全球坐标系的空间位置、方向和线性尺度——决定。初始数据足以计算任意参考坐标系下的大地水准面高度数字模型。所开发的技术的便利之处在于，与公认的标准值相比，它可以用于更精确地计算区域和其他领土的赫尔默特参数，因此，可以更准确地转换一般地球和参考坐标系之间的点的三维位置(这些问题将在作者随后的出版物中讨论)。该技术在几个地区得到了认可:新西伯利亚和莫斯科地区，西西伯利亚地区，白俄罗斯共和国的SK42和SK95坐标系，结果以大地水准面高程图的形式图形化呈现。

The article discusses methodological approaches to the problems of performing work in relation to the forest-park green belt of territorial entities and the procedure for establishing its boundaries. The analysis of the legal support of the work is carried out, the most problematic aspects are formulated and possible ways of their solution are given. It has been established that the existing problems are based on the inconsistency of the relevant regulatory documents and the lack of unified methodological and technological approaches to the implementation of such work. To eliminate the established negative aspects that significantly affect the quality of the work performed, a technological scheme is proposed. This scheme has successfully passed adaptation in the territorial formation of the Russian Federation. The result of the implementation was the entry into the Unified State Register of Real Estate of information on the formed boundaries of the forest-park zone of the city of Tomsk.
