Visualisation service (WMS) of the Map of Bismuth Isovalues (Geochemical Atlas of Spain, 2012).

Visualisation service of the Map of Bismuth (Bi) isocontents, one of the chemical elements obtained in the Geochemical Atlas of Spain Project, distributed in stream sediments (14,864 samples), superficial soils (0-20 cm.) (13,505 samples) and deeper soils (20-40 cm.) (7,682 samples).铋（Bismuth, Bi）等值含量图可视化服务，所涉元素为西班牙地球化学图集项目（Geochemical Atlas of Spain Project）涵盖的化学元素之一，相关采样数据来自河流沉积物（14864份样品）、表层土壤（0-20厘米，13505份样品）及深层土壤（20-40厘米，7682份样品）。
