摘　　要：在数字测绘产品中,一个标准而规范的元数据库能够更好的实现信息资源的有效管理和共享。目前的元数据生产方式多种多样,操作步骤繁杂、生产效率低下。结合目前的生产方式,提出了一种新的元数据制作方法,该方法可应用于所有数字测绘产品的元数据制作。以数字地形图元数据制作为例,通过编写FME元数据提取模板,从元数据的概念、制作流程、制作的关键技术3个方面详细地描述了制作方法。经项目实施和大批量测试,验证了该技术方法高效、便捷,有较高的推广价值。In digital surveying and mapping products,a standardized and normative metadata can better realize the effective management and sharing of information resources.At present,there are many ways to produce metadata,but its operation steps are complex and its production efficiency is low.Combined with the current production mode,a new method of making metadata is proposed,which can be applied to the production of metadata of all digital surveying and mapping products.Taking the production of digital topographic map metadata as an example,by compiling FME metadata extraction template,this paper describes the efficient and convenient metadata production method in detail from three aspects:the concept of metadata,production process and key technologies.Through the project implementation and mass testing,it is verified that the technical method is efficient,convenient and has high promotion value.
