摘要
为突破传统地质资料分立的查阅模式,实现图文数据的无缝衔接,显著提升地质信息的获取效率与利用深度,文章以全国地质资料馆为例,开展基于地质数据开发产品的文本与空间数据关联技术的研究。针对PDF格式地质报告与地质图两类核心数据,采用空间关键词提取与匹配技术SKEM(Space Keyword Extraction and Matching),实现文本内容与空间位置的智能关联。通过构建地质报告关键词与地质图空间要素的映射关系,开发出支持交互式阅读的产品系统,用户点击报告中的文本标签即可自动定位至对应地质图区域。研究表明,该方法不仅优化了科技人员及公众的用户体验,更通过增强图面信息关联性促进了地质知识的传播,为地质科学服务经济社会发展与生态文明建设提供了高效的数据支撑。
To break through the traditional separation retrieval mode of geological resources,achieve seamless integration of graphic and textual data,and significantly improve the acquisition efficiency and utilization depth of geological information,this paper takes the National Geological Archives of China as an example to conduct research on text and spatial data correlation technology based on geological data development products.For the two core data types of geological reports in PDF format and geological maps,SKEM(Space Keyword Extraction and Matching)technology is used to achieve intelligent correlation between text content and spatial location.By constructing a mapping relationship between geological report keywords and spatial elements of geological maps,a product system that supports interactive reading has been developed.Users can automatically locate the corresponding geological map area by clicking on the text label in the report.The research shows that this method not only optimizes the user experience for technical personnel and the public,but also promotes the dissemination of geological knowledge by enhancing the relevance of map information,providing efficient data support for geological science to serve economic and social development and ecological civilization construction.
