ABSTRACT

There are several surveying methods whose practical function is to determine the areas of land, distances, heights, the amount of earthwork, and to produce reduced images of the earth's surface. The research looks at how geodetic and remote sensing methods can be used, and the results they provide in quarry surveying. The most important in quarry surveying is to get an accurate land surface for calculation of the volume of mineral resources. After quarries surveying, it is possible to calculate the amount of remaining mineral resources. Within the framework of the research, were performed surveying in quarries with geodetic surveying and remote sensing methods. For geodetic surveying was used GNSS receiver and a robotic total station, but from remote sensing methods were used aerial photography and aerial laser scanning. The most important reason why it is important to get an accurate surface and make an accurate volume calculation in quarry surveying is the economic factor. The economic analysis was carried out using a comparison method based on volume, market price and natural resources tax. The research presents the advantages and disadvantages of each surveying method and explains the results obtained, based on economic calculations. The main conclusion is that the accuracy of the preparation of land surface relief models is based mainly on economic calculations because mineral resources are a commodity that is bought and sold for which tax is payable.
