2021版“天地图·陕西”矢量数据融合方法研究

Research on the Vector Data Fusion Method of the 2021 Version of"Tianditu·Shaanxi"

基于2020版“天地图·陕西”矢量数据,统筹各类数据资源,按照《天地图数据融合技术要求》,采用统一的数据规格,制定科学的矢量数据融合思路与方法,对道路、铁路、居民地、水系、绿地、政区及境界、地理单元七类矢量数据开展更新融合,提升“天地图·陕西”数据的质量和服务能力,为后续多源多尺度数据的融合更新工作提供参考。

Based on the 2020 version of"Tianditu·Shaanxi"vector data,this paper coordinates various data resources,adopts unified data specifications,and formulates scientific vector data fusion ideas and methods in accordance with the"Tianditu Data Fusion Technical Requirements".Seven types of vector data,including residential areas,water systems,green spaces,administrative districts and boundaries,and geographic units,are updated and fused to improve the quality and service capabilities of the"Tianditu·Shaanxi"data,which provide a reference for the subsequent fusion and update of multi-source and multi-scale data.
