作为基础建设的首要环节,工程勘察通过对地形、地质及水文等要素的测绘、勘探、测试及综合评定,提供建设所需的基础资料与可行性评价。随着计算机技术发展和原始资料的积累,勘察信息的共享和知识的提取需要元数据描述和表达,借鉴地理空间元数据标准化研究成果,基于XML语言,组织工程勘察元数据信息服务模型。研究证明,基于XML提供工程勘察元数据服务是可行的、高效的。该方法同时为工程领域信息共享,知识提取等提供有意义的参考。
As the most important part of infrastructure construction, engineering survey provides the basic information and feasibility assessment for construction through the mapping, exploration, testing and comprehensive assessment of the topography, geology and hydrology. With the development of computer technology and the accumulation of original data, the sharing of survey information and the extraction of knowledge require metadata description and expression. Based on the research results of geospatial metadata standardization, the metadata information service model of engineering survey is organized based on XML language. Research shows that it is feasible and efficient to provide metadata for engineering survey based on XML. The method also provides a meaningful reference for information sharing and knowledge extraction in engineering field.
