摘要
针对新疆1∶50 000海量分幅DLG数据整合拼接及接边融合问题,介绍了如何利用可视化编程处理软件FME,程序化实现快速拼接海量分幅DLG数据和处理DLG数据存在的接边处拓扑关系错误,尤其解决如面状房屋、植被和地貌面状接边处存在的重叠和空隙问题。为分幅DLG数据接边处理提供一个很好的解决方案。
This article in view of the Xinjiang 1∶50 000 mass of DLG data integration and edge fusion problems, introduces how to rapidly achieve stitching the massive DLG data, and processing the topological relationship mistakes of DLG data with the visual pro-gramming software—FME, especially solves the polygon planar elements in the problems of edge overlap and gap.The data processing method provides a good solution for framing DLG data.
