The basic geographic data is usually recorded and stored for sheet and layer, so the geographic entities may have gaps in the map sheet boundary during the process of data acquisition. In this paper, combined with map splicing theory, we put forward a seamless merging method of polygon geographic feature considering both geometric relationships and feature attributes, and this method has been achieved with the function of ArcGIS Engine in Microsoft Visual Studio 2008 development environment. Experiments show that this method is effective to achieve the physical seamless and logical seamless of polygon geographic entities, it is feasible.%基础地理信息数据通常是分幅、分层记录和存储的,分幅采集和处理过程中地理实体可能会在图幅边界产生缝隙.本文结合地图拼接理论,提出了一种兼顾几何关系和属性特征的面状地理要素无缝拼接的方法,并利用ArcGIS Engine提供的功能,在Microsoft Visual Studio 2008的开发环境下实现了这种方法.实验证明,该方法有效地实现了面状地理实体的物理无缝和逻辑无缝,是切实可行的.
