| Description |
About 25 billion tons of solid waste are saved up for territories of Ukraine as a result of activity of industrial enterprises. This waste negatively influences natural landscapes and ecological conditions. Each dump is a source of air and water pollution with various toxins. From here follows the need of calculating the parameters of waste dumps for their classification and further reorganization. It is possible to determine parameters, having obtained a three-dimensional model of a dump. Parameters, which characterize them, are subdivided in physical, thermal, chemical and economic. The analysis of the basic physical parameters of the waste is made: the area, shape, angle of natural slope, height, volume, physical stability, erosion status, proportion of vegetable cover, tendency to dust formation. When considering the methods of creating three-dimensional models the uniform grid was chosen. This model describes coordinates of separate points of a surface in the following way. To each node of a grid with indexes (i, j) the value of height Zij is attributed. To indexes (to i, j) correspond certain values of coordinates (x, y). The distance between the nodes is identical - dx on axis x and dy on axis y. To each node corresponds the value of height z. To calculate the height or any point, within the grid the interpolation of the values of coordinates z of the nearby nodes is carried out. When constructing waste dumps models software OziExplorer was selected. (Interactive mapping system with OziExplorer software module OziExplorer3D), which uses a uniform grid. To create a three-dimensional model in OziExplorer3D we need a waste dump image, file of binding to the grid and the values of the heights of surface points corresponding to the coordinates. As the altitude data files SRTM (Shuttle Radar Topography Mission) were selected. To construct a threedimensional dump model we also need the corresponding image surface. You can use the program SASPlanet to get the required picture. SASPlanet is a program designed for viewing and downloading satellite images of high resolution and conventional maps submitted by such services as Google Earth, Google Maps, Bing Maps, DigitalGlobe, “Satellite Imagery," Yandex. But unlike these services, OziExplorer allows you to leave all the downloaded maps in the computer and have the opportunity to view them even without internet connection. Проаналізовано та обрано метод побудови тривимірних моделей. Визначено основні параметри породного відвалу, що можуть бути обчислені за допомогою 3D-моделі. Побудовано моделі породних відвалів та визначено отриману точність по висоті. |
