摘要：Classic mapping technologies for acquisition of information on localisation of points of detailed planimetric survey during creation of survey sketches are influenced with new digital and communication possibilities. Weak points of this classic technology of survey sketches processing are detected and replaced by new communication technologies exploiting mobile telephone networks. There is a condition to develop new technologic process using electronic sketches, digital tacheometers and central databases for processing of survey sketches. Building of the complete system of supporting geodetic web services and exploitation of central databases with functional dispatching of services and controls during processing are important. The paper analyses classic mapping technologies from the point of view of their advantages and disadvantages and adverts to weak points of present technologies. The possibility to send data in digital mobile networks environment and possibilities of transfer of data designated as CSD (circuit switched data) is analysed. The possible risks of data transfer by GPRS are described. Creation of so-called electronic sketch is an integral part of use of new technologies. This concept is not only explained but also the exploitation of electronic sketches for specific task (i.e. creation of survey sketches) is described. The survey sketches serve for update of the cadastre. The stages of processing of survey sketch, numeration of detailed survey points and characteristics of elements in this technology for resulting geodata transfer to the central database are described. The process of creation of survey sketch by this new procedure in the specific condition of the Czech Republic, where the communication with the central database of the cadastre of real estates is realized through so-called "text exchange format", is explained. Furthermore the advantages of mobile processing of survey sketches against classic technologies are discussed. The premises of successful integration of this new technology into the praxis are summarized in the conclusion
