| 摘 要： | 农用地分等定级估价成果在土地管理中具有广泛的应用前景,促进了土地管理由"数量管理"向"数量和质量并重管理"的转变.农用地分等定级估价成果数据量大、数据形式多样,数据共享困难.元数据作为信息共享有效途径,可以方便用户快速、准确地发现、访问、获取和使用所需数据.通过探讨元数据技术在实现农用地分等定级估价成果信息共享中的应用,提出相应的元数据标准和共享体系.

| Abstract: | The results of classification,gradation and valuation of agricultural land can be widely used to improve the land management from "quantitative management" to "quantitative and qualitative management".However,it is difficult to share the results due to the amount and variety of the data.Metadata of the results is effective information to the users,who can discover,access,obtain and share the data.This paper proposes the metadata standard and the data share framework of the results by exploring the application value of the data. |
