DESIGNING ENVIRONMENTALLY HAZARDOUS OBJECTS BY MEANS OF GEOGRAPHIC INFORMATION SYSTEMS
Komunalʹne Gospodarstvo Mìst
The article deals with the current problem of solid waste disposal. Also the use of geoinformation technologies in the design of environmentally hazardous facilities. The sequence of actions in case of reconstruction of a land plot for the construction of a solid waste landfill is described in detail. It shows how you can use geographic information systems to speed up and better accomplish the task. The convenience of using geographic information systems when planning such tasks is obvious. It
... s advisable to use geographic information systems when planning environmentally hazardous facilities. This is due to the complex nature of the problem. This requires the involvement of additional spatial data. It is the geographic information system that will allow the use of all data in the complex based on the principle of their spatial position. You can also use data models to support the creation, validation, and correction of information. In a geographic information system, you can create a geodatabase. This will create a 3D model of a solid waste landfill. The 3D model allows you to better represent the terrain. Creation of a triangulation network will allow to correlate all layers created in the geodatabase. The triangulation network is created from 3D terrain points. It allows you to get a three-dimensional model of a high-altitude polygon. This provides many possibilities in the future. It will be possible to interpret 3D models with high-precision engineering systems. This allows you to carry out any geometric measurements, build sections and profiles, as well as monitor activities at the solid waste landfill. Based on these data, it is possible to measure the volumes of household waste, areas, the height of the landfill in terms of the height of the actual relief and the level of groundwater, the altitude characteristics of the landfill and slopes to compare them with the standard indicators. The three-dimensional model will make it possible to identify inconsistencies between the actual boundaries of the polygon with the cadastral boundaries of the site allocated for these purposes. With the help of geographic information systems, simplicity, speed and clarity in the formation of conclusions and decision-making will be provided.
