Abstract: A method and a device to supervise a power network are described, where data representing at least a part of the power network are processed and transformed into graphical data, the graphical data are displayed on a graphical display unit as a first visualization of the power network at a less detailed zoom level and a user request on how to modify the first visualization is processed, where the user request is received from a user input unit. In the first visualization, there is displayed at least one selectable element which is selectable via the user input unit and which is assigned to a predefined portion of the power network and to a more detailed zoom level. After a user request is received indicating that the selectable element was selected by a user, the predefined portion of the power network is displayed at the more detailed zoom level as a second visualization on top of the first visualization.

Abstract: A method and system are disclosed for storing, retrieving and otherwise handling two and/or three dimensional image data forming a picture or image. The picture is defined by a plurality of levels, each level including a plurality of subpicture areas corresponding to a different level of image data resolution relative to image data resolution levels corresponding to subpicture areas in other levels. The method and system include selecting a subpicture element having image data for inclusion in the picture and identifying a subpicture area in which the subpicture element may be placed. The method and system further include placing the image data of the subpicture element in the identified subpicture area.
