Introduction

Soil quality and soil protection are an increasingly important issue in all countries. Whether it is for land development, waste recycling, evaluation To assess the impact of soil usage on water quality, or to maintain soil function, it is increasingly necessary to understand soils and describe them. description and analysis. Although many standards have been established to describe and analyze soils, because soil-related research is generally carried out by professional organizations The research results usually need to be submitted to the business entrusting party or management department, and according to the provisions of the law, the relevant government departments should also Therefore, it is very necessary to formulate digital exchange standards for soil data. Many projects involve the description, sampling and analysis of soils, which result in soil data, where sampling and analysis are usually not necessary. required. Soil properties are estimated in terms of soil-generating layers or soil layers at specific depths. This vertical sequence constitutes the soil profile. The amount and level of detail of soil description, sampling and analysis varies widely from project to project. In addition, available metadata, sampling and analysis design and professional terms are also different. Because of this, the exchange of soil data is very difficult. Due to the wide diversity of soil data itself and its use, data exchange in hard copy (paper) form is now Less appropriate, especially considering that in some land development or environment-related decisions, soil research is often not the end point in itself, but only as part of the required data. Therefore, soil data needs to be used in conjunction with data from other sources such as environmental, land use or statistical data. Therefore, it is necessary to use a geographic information system (GIS). The purpose of this document is to provide an Generic process for recording various soil-related data for data exchange without any prerequisites for information systems. This document proposes a data format based on Extensible Markup Language (XML). The XML language consists of a set of platform- and software-independent It consists of information coding rules. The main advantage of using XML is that the language is the standard for data transmission over the Internet. Most existing software tools Both the program interface and the program interface support processing and querying XML files, and XML can be converted into other data formats according to user purposes or needs for further processing or displaying, or converting XML files to and from relational databases. In addition, in order to facilitate the exchange of this type of data with other environmental data This document also uses a specific XML format for geographic information, GML. This document specifies the method for encoding soil data (metadata, soil description, geography and time, etc.), including relevant specifications and XML codes code. In addition, to maintain compatibility between revisions of this document, coding guidelines are provided for other information not currently taken into account. this These basic principles enable data recipients or users to read and/or decode soil-related information in an unambiguous, secure and retrievable manner. Figure 1 shows the data flow for the soil quality project, which is generic to the many forms of application to which this document applies.
