SERENA_EJPSOIL_AT_SOILSEALING_SEALINGDEGREE

The internal EJP SOIL project SERENA contributed to the evaluation of soil multifunctionality aiming at providing assessment tools for land planning and soil policies at different scales. By co-working with relevant stakeholders, the project provided co-developed indicators and associated cookbooks to assess and map them, to report both on soil degradation, soil-based ecosystem services and their bundles, under actual conditions and for climate and land-use changes, at the regional, national, and European scales. This data was prepared according to the methodology of SERENA Soil Sealing cookbook. For Austria, the application was carried out at regional scale. The map of soil sealing (soil threat) was based on classification of multitemporal satellite images and photointerpretation. The methodology uses vegetation and backscatter indices calculated over time series of images, and decision rules. The semi-automatic classification supports the subsequent photointerpretation phase based on national orthophotos and other free VHR satellite images.欧洲土壤联合计划（EJP SOIL）旗下SERENA项目聚焦土壤多功能性评估，旨在为多尺度土地规划与土壤政策制定提供评估工具。本项目联合相关利益相关方，研发了协同共建的评估指标及配套操作指南，用于指标的评估与空间制图；同时可针对实际现状，以及区域、国家及欧盟尺度下的气候变化与土地利用变化情景，报告土壤退化、土壤支撑的生态系统服务及其服务组合的相关情况。 本数据集严格遵循SERENA土壤封存操作指南的方法制备。针对奥地利区域，本次应用以区域尺度实施。土壤封存（土壤威胁）分布图基于多时间序列卫星影像分类与遥感影像解译构建而成。该方法依托影像时间序列计算得到的植被指数与后向散射指数，并结合决策规则实现分类。半自动分类流程可为后续基于国家正射影像及其他免费超高分辨率（Very High Resolution, VHR）卫星影像开展的遥感影像解译环节提供技术支持。
