Operations in a worksite () are managed by networking at least some items of apparatus () which perform tasks in connection with said worksite and which receive and/or send data. The items of apparatus are organized in hierarchical levels according to a determined dependency relationship of the worksite. Communications are made with an electronic data network comprising management means () cooperating with a plurality of communications interfaces (-), a given item of apparatus having a data link with a specified communications interface. The management means stores a correspondence between each item of apparatus and an address structure reflecting the hierarchical position of that item of apparatus () in the determined dependency relationship of the worksite. It uses that correspondence to establish a communications link with a selected item of apparatus, via its communications interface, in response to a call addressed with an address structure reflecting the hierarchical position of that selected item of apparatus.

Method and apparatus for managing information exchanges between apparatus on a worksite

The invention relates to a method for controlling a surface-modifying machine, wherein information on the desired condition and on the actual condition of ground to be prepared is provided and is used to derive control statements for the machine based on a comparison of the desired and the actual condition. The information on the actual condition is represented by a point cloud as a spatial distribution of discrete surface points. In order to derive control statements, at least two surface points each from the point cloud are used for every horizontal position so that non-differentiated information can be derived that for example also allow to identify various planes.
