| 摘 要： | 地质图编制专业性强、工作量大,编图环节繁琐,而人工智能、大数据等新一代信息技术的快速发展,为中国地质图的编图技术发展提供了支撑。在地质大数据环境下,提出基于地质知识驱动的地质编图技术,通过构建地质编图时空综合模型和地质代号智能识别模型,可以对多图幅的沉积岩、侵入岩、火山岩、变质岩、构造等地质要素进行人机交互式、自动化、智能化地图元综合、断层简化、线形圆滑、图幅接边等。近年来,基于该技术在青海东部地区、河南洛阳、郑州地区及京津冀多地区开展的编图实践表明,该编图技术能够显著提高地质编图工作效率,具有实际应用意义。

| Abstract: | In order to improve the efficiency of specific compilation of geological map and reduce human workload, it is necessary to develop a new method to update the previous geological maps compiled decades ago. After studying the information technology such as AI & BigData, the authors constructed the spatial-temporal model of generalization and the intelligent model of the geological annotation. Then a new technology was developed with which small scale geological maps can be converted to general scale geological maps in a big data environment through compilation. The technology for mapping is called iMapower. Practically, the geological features, such as sedimentary rocks, intrusive rocks, volcanic rocks, metamorphic rocks and structures, can be processed intelligently, interactively, automatically with iMapower based on geological knowledge. The processing procedures include geological body merging, geoline simplification, fault generalization, feature representation, legends illustration, etc. In its application to several pilot areas such as eastern Qinghai Province, Luoyang area, Zhengzhou area and Jingjinji area, the efficiency is obviously improved. The iMapower is proved to be scientific and effective. |
