摘　　要：提出一种避免冲突和压盖的电子地图标注框架。通过格网号描述所有注记位置,把点、线、面3种要素的注记有机统一在相同框架下,使已标注的要素和未标注的要素关联起来。该格网地图注记算法简洁高效,具有良好的实时性和标注效果,能满足高质量地图注记的要求。The paper presents a novel collision and overlapping free labeling framework, under which all label positions are indicated by grid number so that labels of points, arcs and polygons are organically linked by grids, and so do labeled objects and unlabeled objects. The algorithm is of good simplicity, efficiency and effects to meet the demand of high quality map label placement, and is successfully applied in commercial GIS.
