Wide-Area Electric Grid Visualization Using Pseudo-Geographic Mosaic Displays

This paper introduces a new technique for wide-area visualization of information about electric power grids known as a pseudo-geographic mosaic displays (PGMDs). The PGMD approach uses dynamically created geographic data view (GDV) objects to show information about the attributes of different electric grid objects, and then arranges them on the screen to maximize the used display space. The paper presents the PGMD algorithm and then discusses design approaches to maximize their usability. Results are presented for several large-scale electric grids.
