Metallic Mining Development Potential Index

This global dataset continuously ranks from >0 (minimal) to 1 (highest) all suitable lands at a 1-km resolution for metallic mining (e.g. gold, silver, copper). These data are derived from the weighted summary of four criteria maps: 1) proxy yield values based on deposit size and numbers, 2) distance to demand centers, 3) distance to major roads, and 4) distance to railways or ports. Included with these data are: a) the classified version of the continuous DPI, b) the corresponding classified uncertainty dataset, c) detailed sensitivity tables for all criteria used in the analysis, and d) full description of the constraints and criteria used in the analysis with the Analytic Hierarch Process (AHP) pairwise comparison matrix and resulting criteria weights derived from AHP.本全球数据集以1公里空间分辨率，对所有适用于金属采矿（如金、银、铜）的土地进行连续评分，评分范围为大于0（最低适宜性）至1（最高适宜性）。该数据集基于四类准则图层的加权汇总生成：1）基于矿床规模与数量的代理产量值；2）至需求中心的距离；3）至主要道路的距离；4）至铁路或港口的距离。随数据集一同提供的内容包括：a）连续矿床潜力指数（DPI）的分类版本；b）对应的分类不确定性数据集；c）本次分析所用全部准则的详细敏感性表格；d）本次分析所采用约束条件与准则的完整说明，包含层次分析法（Analytic Hierarchy Process，AHP）的两两比较矩阵及由其推导得到的准则权重。
