This paper presents an outdoor Radio Environment Map (REM) for the television band applied to the UPCCampus Nord, which has a Manhattan like structure. A measurement campaign of the received TV signal in the streets and squares of the campus was carried out. Two specific interpolation algorithms were analysed in the study, namely Kriging and a modified version of the Inverse Distance Weighted (IDW) algorithm. In addition a set of verification points were also measured and used to check the goodness of the interpolation methods used for REM implementation. Finally, a MATLAB based application was developed, which allows the user to obtain the list of occupied and free TV channels in any outdoor position of the Campus.
