摘要
基于城市大比例尺数字线划数据、数字正射影像数据、数字高程模型数据等多源数据,研究了基于多源数据融合的数据处理关键技术。在多源数据管理与更新模型对数据有效管理组织的基础上,利用多源数据融合生产,更新了电子地图,实现了多源数据的集约利用,完成了福州市1∶2000比例尺矢量电子地图、影像电子地图和晕渲电子地图的更新制作。
Based on digital line drawing data, digital orthophoto data, digital elevation model data and other multi-source data in urban large-scale, this paper studied the key technology of data processing based on multi-source data fusion.Then, the multi-source data fusion was used to produce and update the electronic map to realize the intensive utilization of multi-source data based on the effective management and organization of data through the multi-source data management and update model.Finally, this paper completed the update and production of Fuzhou 1:2000 scale vector electronic map, image electronic map and shading electronic map.
