For solving quality problems on utilizing exported data from distribution geographic information system（GIS） to distribution network evaluation and planning， a set of rule-based data verification and correction（DVC） methods are proposed， including the DVC methods for data tables， topology structure and electrical parameters. A man-machine interactive system for DVC is developed thereafter， which has been used in practical distribution network evaluation. Actual application indicates that the methods proposed can effectively verify and correct the GIS exported data， thus can meet the requirements of advanced analysis and calculation such as distribution network evaluation and planning.
