土质. 土壤相关数据的数字交换

[中文适用范围]： 本国际标准描述了如何以数字方式交换土壤相关数据。 它旨在促进个人和组织之间通过数字系统交换有效、清晰描述和指定的土壤相关数据，并使任何土壤数据生产者、持有者或用户能够以明确的方式查找和传输数据。 [外文原描述]： ISO 28258:2013 describes how to digitally exchange soil-related data. It aims to facilitate the exchange of valid, clearly described and specified soil-related data between individuals and organizations via digital systems, and enables any soil data producer, holder or user to find and transfer data in an unambiguous way. It contains definitions of features, several parameter specifications and encoding rules that allow consistent and retrievable data exchange. It also allows the explicit geo-referencing of soil data by building on other International Standards, thus facilitating the use of soil data within geographical information systems (GIS). Because soil data are of various origins and are obtained according to a huge variety of description and classification systems, ISO 28258:2013 provides no attribute catalogue, but a flexible approach to the unified encoding of soil data by implementing the provisions of ISO 19156 observations and measurements (OM) for use in soil science.
