A highly interactive operator workstation for a distribution automation system using spatial data management was developed. The spatial data structure, called MD-tree, manages a large amount of equipment data and its background map data hierarchically. By its rapid range searching and the related techniques, fast response time and a user-friendly interface are obtained on a reduced instruction set computer (RISC) workstation without a hardware accelerator. The system configuration, the graphic data management method using the MD-tree, and the sophisticated graphic functions and operations are described
