Digital Soil Mapping

DSM is a collaborative workspace for researchers working on digital soil mapping in Australia. This workspace is the initiative of the Advisory Group on Digital Soil Assessment, a working group of the National Committee on Soil & Terrain. The website is part of an interoperable web-GIS maintained by the Centre for eResearch and Digital Innovation (CeRDI) at Federation University Australia (FedUni).
The International Union of Soil Sciences Digital Soil Mapping Working Group defines DSM as "creation and the population of a geographically referenced soil database, generated at a given resolution by using field and laboratory observation methods coupled with environmental data through quantitative relationships."
Digital Soil Mapping (DSM) utilises numerical methods and information technologies to produce predictive maps of soil types and their properties. DSM relies on traditional field mapping, observations and laboratory analyses for soil data but also utilises spatial models of landscape terrain and remotely-sensed properties. Typically numerical methods such as interpolation algorithms and data mining are used to create the maps.
OzDSM in collaboration with CeRDI is developing a digital soil mapping tool, and a demonstrator version is displayed on the site. A range of data is included, such as nutrient budgets and soil pH, and with extra data available for the Corangamite Catchment Management Authority region including landslides, erosion and salinity.

数字土壤制图（Digital Soil Mapping，简称DSM）是澳大利亚数字土壤制图领域研究者的专属协作工作空间。该工作空间由国家土壤与地形委员会（National Committee on Soil & Terrain）下属工作组——数字土壤评估咨询小组（Advisory Group on Digital Soil Assessment）发起设立。该网站是澳大利亚联邦大学（Federation University Australia, FedUni）电子研究与数字创新中心（Centre for eResearch and Digital Innovation, CeRDI）维护的可互操作网络地理信息系统（web-GIS）的组成部分。
国际土壤科学联合会（International Union of Soil Sciences）数字土壤制图工作组将DSM定义为：'通过定量关联方法，结合实地与实验室观测手段与环境数据，以指定分辨率生成并填充具备地理参考属性的土壤数据库。'
数字土壤制图（Digital Soil Mapping，简称DSM）采用数值方法与信息技术，制作土壤类型及其属性的预测性地图。其依托传统野外制图、实地观测及实验室分析获取土壤数据，同时还借助景观地形的空间模型与遥感反演属性数据。通常会采用插值算法、数据挖掘等数值手段生成此类地图。
OzDSM与CeRDI合作开发了一款数字土壤制图工具，其演示版本已在该网站上线。平台涵盖养分收支、土壤pH值等多类数据；同时可提供科兰加迈特流域管理局（Corangamite Catchment Management Authority）辖区内的额外数据集，涵盖滑坡、水土流失与盐渍化相关信息。
