EN Radio Environment Map (REM) is a tool frequently envisaged to be one of the technical enablers for practical deployment of secondary systems operating in the legacy bands and following some of the spectrum sharing policies. However, the creation of such a map requires the detailed knowledge about the parameters of the incumbent system that has to be protected. The ways, how the information is obtained and stored in the system has to be accurate and cannot require involvement of too much resources, e.g., for collecting the measurement samples. Thus, in this paper we provide a discussion on the ways how the ordinary kriging algorithm can be applied for creation of an indoor and outdoor coverage map of the TV signal — a map that could be used by REMs for management of secondary transmission. Based on the real signal measurements conducted in Poznan, Poland, the map was calculated using various approaches, which are compared and discussed. In this paper the new approaches have been proposed on how to consider the attenuation of the walls during the creation of the map.
