Dataset of cartographic embankment lines to generalise

A dataset of roads and cartographic embankment lines that are too close to each other for a cartographic representation at the 1:25k scale. This dataset is derived from IGN topographic data, and was used to test the ReBanker generalisation algorithm. A set of displaced lines obtained with the ReBanker algorithm is also provided for future comparisons.本数据集收录了在1:25000比例尺制图中彼此间距过小、无法实现正常制图表达的道路与制图堤岸线要素。该数据集源自法国国家地理研究院（Institut Géographique National，IGN）地形数据，曾用于测试ReBanker地图综合算法。此外还提供了通过ReBanker算法生成的偏移线要素集，以供后续对比研究使用。
