SCMaP — Landsat — Germany, 1984-2014

The Soil Composite Mapping Processor (SCMaP) is a new approach designed to make use of per-pixel compositing to overcome the issue of limited soil exposure due to vegetation. Three primary product levels are generated that will allow for a long term assessment and distribution of soils that include the distribution of exposed soils, a statistical information related to soil use and intensity and the generation of exposed soil reflectance image composites. The resulting composite maps provide useful value-added information on soils with the exposed soil reflectance composites showing high spatial coverage that correlate well with existing soil maps and the underlying geological structural regions.土壤复合制图处理器（Soil Composite Mapping Processor, SCMaP）是一种创新性方法，旨在利用逐像素合成（per-pixel compositing）技术，解决因植被覆盖导致的土壤暴露受限问题。该方法可生成三类核心产品层级，用于开展土壤的长期评估与土壤分布制图工作，具体涵盖裸露土壤分布、与土壤利用及强度相关的统计信息，以及裸露土壤反射率影像合成产品的生成。最终生成的合成制图可为土壤研究提供极具价值的增值信息：其中裸露土壤反射率合成产品空间覆盖度高，且与现有土壤图及地下地质构造区域匹配度良好。
