The GlobalSoilMap initiative significantly inspired the DOSoReMI.hu (Digital, Optimized, Soil Related Maps and Information in Hungary) project, which was started intentionally for the renewal of the national spatial soil data infrastructure in Hungary. The main objectives of our work has been to broaden the possibilities, how demands on spatial soil related information could be satisfied in Hungary, how the gaps between the available and the expected could be filled with optimized digital soil (related) maps. During our activities, we have significantly extended the potential, how goal-oriented, map-based soil information could be created to fulfill the requirements. Primary and specific soil property, soil type and certain tentative functional soil maps were compiled. The set of the applied digital soil mapping techniques has been gradually broadened incorporating and eventually integrating geostatistical, machine learning and GIS tools. Soil property maps have been compiled partly according to GlobalSoilMap.net specifications, partly by slightly or more strictly changing some of their predefined parameters (depth intervals, pixel size, property etc.) according to the specific demands on the final products. The set of primary and derived soil properties specified by GSM for the required layers have been almost entirely prepared. The web publishing of the results was also elaborated creating a specific WMS environment. The map products are published on the www.dosoremi.hu website. The maps are serviced in two different ways. In the atlas version, map layouts are collected and published for application as graphical elements. Interactive maps are produced for browsing over alternative base map background. Most relevant information on the renewed Hungarian Spatial Soil Data Infrastructure, on its compilation and applicability are also communicated on the site.

The nationwide, thematic digital soil maps compiled in the frame and spin-off of our research have been utilized in a number of ways. Programs or studies dedicated to the designation of areas suitable for irrigation; risk modelling of inland excess water hazard; mapping of potential habitats; spatial assessment and mapping of ecosystem services were heavily relied on the novel type spatial soil information. These programs however frequently required certain modifications of the standard GSM products due to various reasons. The paper presents the finalized GSM conform results of DOSoReMI.hu, together with their various national applications. Some reasons behind the application of modified GSM products are also presented.

匈牙利开发符合GSM标准的DSM产品及其功能的进展

GlobalSoilMap计划极大地启发了DOSoReMI.hu(匈牙利的数字化,优化,土壤相关地图和信息)项目,该项目是有意启动的,旨在更新匈牙利的国家空间土壤数据基础设施。我们工作的主要目标是拓宽可能性,如何在匈牙利满足对空间土壤相关信息的需求,如何用优化的数字土壤(相关)图填充可用和预期之间的差距。在我们的活动中,我们极大地扩展了潜力,即如何创建基于目标的,基于地图的土壤信息来满足要求。编制了主要和特定的土壤特性,土壤类型以及某些暂定的功能性土壤图。结合并最终整合了地统计,机器学习和GIS工具的应用数字土壤测绘技术集已逐渐扩大。土壤属性图的部分编制是根据GlobalSoilMap.net规范,部分是根据最终产品的特定要求,通过略微或更严格地更改其一些预定义参数(深度间隔,像素大小,性质等)来进行的。GSM为所需图层指定的主要土壤属性和派生土壤属性集几乎已全部准备好。还详细创建了结果的Web发布,以创建特定的WMS环境。这些地图产品已发布在www.dosoremi.hu网站上。这些地图以两种不同的方式提供服务。在图集版本中,收集地图布局并发布为图形元素以供应用。生成交互式地图,以浏览替代基础地图背景。该网站还传达了有关更新后的匈牙利空间土壤数据基础设施的最相关信息,包括其编译和适用性。

在我们的研究框架中和衍生出来的全国范围内的专题数字土壤图已经以多种方式得到利用。专门用于指定适合灌溉的地区的计划或研究;内陆水过多危害的风险模型;绘制潜在的栖息地;生态系统服务的空间评估和绘图在很大程度上依赖于新型的空间土壤信息。但是,由于各种原因,这些程序经常需要对标准GSM产品进行某些修改。本文介绍了DOSoReMI.hu的最终GSM一致性结果,以及它们在各个国家/地区的应用。还介绍了应用修改后的GSM产品的一些原因。
