1. A method for use in a robotic work tool system comprising a server and a robotic work tool arranged to operate in an operational area based on a satellite navigation sensor, wherein the method comprises:
receiving one or more safety boundaries defining boundaries for operating based on the satellite navigation sensor and storing the one or more safety boundaries in a safety map of the operational area,
receiving one or more zone boundaries defining boundaries for operating based on the satellite navigation sensor and storing the one or more zone boundaries in a zone map of the operational area,
and
operating based on the satellite navigation sensor according to the one or more zone boundaries and the one or more safety boundaries, wherein the one or more zone boundaries are within at least one of the one or more safety boundaries and the one or more safety boundaries are related to safety concerns for the robotic work tool and wherein the method is characterized in that
the one or more zone boundaries defining boundaries for operating based on the satellite navigation sensor are received by the server and in that
the method further comprises confirming the one or more safety boundaries on location in the operational area prior to operating according to the one or more safety boundaries.
