Abstract: The data map is stored according to sheet or block in embedded GIS system, thus causing seam in the cutting-border for physical integrate area feature. Based on area feature coordinate data, and constructing block cut-edge associate table, this article describes seamless unite process of cutting-area feature on embedded studio, drawing whole geographical entity smoothly.

Key words: Embedded GIS, Seamless GIS, Block-border area feature, Cut-edge associate table

摘要： 嵌入式GIS地图数据是分幅、分块记录和存储的，物理完整的面状地理实体在切割边界会产生缝隙。该文在面要素坐标数据支持的基础上，在内存构建图块切割边关联索引表中，描述了在嵌入式硬件平台上快速实现面状地理要素的无缝拼接的过程，实现了面状地理实体的逻辑无缝。
