The using of GPS-RTK technology for creation of the open-pit mine basic map

The comparison of accuracy of results of methods used for measuring of detailed points of drawing of the open-pit mine map with results of the method GPS-RTK is realized in the paper. The first part of the article deals with classical methods of tacheometry as wire tacheometry, reducing tacheometry or tacheometry with electronic tacheometer. In the second part of the article the selective set of coordinates of detailed points measured in the open-pit mine in Jakubcovice nad Odrou is evaluated. The results of comparison written are estimated in the end of the paper as well as some tasks at surveying by means of using GPS-RTK technology in the open pit mine.
