Application of Ott's Mine Coordinate System in the Past and in Present Day

This paper presents the optimization of evaluation of large volume of geographic data. The core of the method is hierarchical decomposition of the set of processes into elementary processes and the allocation of means to these processes. The means can be of three types: hardware, software or human factor, eventually combination of these types. Each elementary process can be processed at one of these means in certain time. Generally, the processes and the means can be interdependent or independent. The described problem can be represented using an oriented graph, where nodes correspond to the processes or the means and edges represent either the interdependence of processes and means, or the processing time of certain process on a given mean. The map of processes is formed on the basis of the graph. This map contains temporal continuity of solutions of sub-processes. Then, the duration of all processes is compiled from this map, which must be less than the time solving a task in the required quality of results. If not, the pairs of sub process-mean are replaced alternative pairs according to the map of processes with lower duration. The special algorithm was designed for this task. If the sum of the durations of all processes complies with solutions, the optimization ends and at this time the sub-processes and their allocated means are defined. The proposed method of data processing was realized in the project of data analysis of storage of gas facilities under certain types of terrain surface in the Czech Republic with the area of 64,350 km 2 .

The beginnings of the mining history date back to ancient times, up to the second century B.C. One field closely related to mining activities is mine surveying. Mine surveying and mapping are disciplines that deal with the surveying and displaying of underground works and mining claims, in which their spatial relationships are determined against the surface. The introductory part of the paper is dedicated to the history and development of the mine surveying discipline and mapping, and to the profession of a mine surveyor. The second part of the article is devoted to historical mining maps produced in Austria, the Czech Republic and Slovakia. Historical mine maps belong to the significant treasures of past times, and from today's perspective they are often considered to be pieces of art. In the time of their origin they belonged to the most sophisticated technical-natural documents that were used for the registration of property rights, and for the performance of mining activities. With regard to the period in which they were created they are accurate, yet there are few records on their history.
