Abstract
In the last few years, interest in the collection of data using remotely piloted aircraft systems (RPAS) has sharply risen. RPAS technology has a very wide area of use; one of its main advantages is its accuracy, timeliness of data, frequency of collecting data and low operating costs. RPAS can be used for the mapping of small, dangerous and inaccessible areas in contrast with ordinary aerial photogrammetry. In the cadastre of real estates of the Czech Republic, it is possible to map out areas by using aerial photogrammetry, so it has been done in the past. However, this is a relatively expensive and complex technology, and therefore we are looking for new alternatives. An alternative would be to use RPAS technology for data acquisition. The testing of the possibility of using RPAS for the cadastre of real estates of the Czech Republic is the subject of this paper. When evaluating results we compared point coordinates measured by geodetic method, GNSS technology and RPAS technology.

remotely piloted aircraft systems (RPAS) appears to be a suitable alternative of data collection for the cadastre of real estates
RPAS as a data collection tool for cadastral purposes is not enshrined in the Czech legislation
Summary
Cadastre of real estates plays an important and irreplaceable role in the lives of people in the Czech Republic, and throughout the world. The usability RPAS (Remotely Piloted Aircraft System) is mostly discussed in the field of cadastre of real estates and mapping. It is a modern and useful technology for the contactless mapping and monitoring of small areas. These systems can provide different types of data, e.g. visible spectral range data, infrared data, multispectral and hyperspectral data, even Lidar data. The Czech Republic border region was mostly mapped using aerial photogrammetry, but it is in most cases with a large aircraft with a calibrated, accurate and very expensive camera, which was adapted for these purposes and equipped by an inertial measuring unit.
