| Abstract: | Quality evaluation of spatial data quality is a problem due to the coexistence of illegibility and randomicity,and traditional evaluation method can not deal with the problem.In the paper,The evaluation method based on Trapeziform Comment Cloud and Dummy Cloud was provided for the DLG evaluation in order to resolve the problem.The test of DLG quality evaluation comparison was done between the studied methods and the traditional weighted average method and fuzzy comprehensive evaluation method.The test resul... |
