| 摘 要： | 一致性是空间数据质量的重要标准。空间数据的一致性探测对于多源、多尺度空间数据的融合具有重要意义。注记是地图的重要组成元素，包含了丰富的地理位置信息。由于制图综合、资料来源等原因，使得多个尺度的注记当中存在大量不一致现象。尝试从栅格地图中进行多尺度注记一致性的探测。在已有的空间目标变化类型基础上，提出了地图注记的12种基本变化类型，对地图注记在不同表达之间的一致程度进行量化表达，并提出了针对栅格地图注记一致性探测的方法。利用该方法对瓦片地图上的不同尺度的注记进行一致性探测与度量，证明了该方法的合理性和有效性。

| Abstract: | Consistency is an important criterion of spatial data quality. Checking the inconsistencies is critical for maintaining the integrity of multi-resolution or multi-source spatial data. Annotation is an important element of the map, which contain abundant geographical location information. Multi-resolution spatial data always contain the inconsistencies of annotations due to measurement methods, data acquisition approaches, and map generalization algorithms. In this paper, we try to use a new kind of raster data which named map tile to detect the consistency information of multi-scale annotations. On the basis of existing space target change type, we put forward 12 types of basic changes, quantify the annotation consistency between the different of map, and put forward the methods of consistency detection for raster map annotation. We use the methods to detect and measure the consistency of annotations in web raster map, it is proved that the methods are reasonable and effective. |
