uDig is our final choice by evaluation and examination to
ten FOSS desktop GIS projects. Some power GIS and SCADA
functions will be developed based on uDig through plug-in
development. In this design, electric diagrams and GIS based
feeder maps are drawn in the same graphic mode with the
consistent topology. The distribution network model is in
accordance with Common Information Model (CIM) in
IEC61970. This section consists of system framework,
