It is possible to conect data for creation of DTM using different measurment technologies. The paper describes different technologies used for collection of data for creation of DTM. First the precise GPS RTK method with the use of GSM/GPRS transmission of corrections is presented. Precise RTK method is used for real time determination of horizontal and vertical coordinates of the points used in the model. This method is very precise and effective. Second method in our research was the photogrammetric method using photogrammetric digital station. Photogrammetric technology using measurements on stereo model from aerial photograph is an interesting alternative for RTK method. Finnaly classical tachimetric method of measurement is presented. This method is considered as the most reliable but also the most time consuming. All presented methods were used for DTM creation of the same test area. The comparisons of the methods and analyses are given in the paper. Conclusions and plans for the future work are presented.
