Non-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 non-metallic mining (e.g. sand and gravel mining). 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1千米空间分辨率，对所有适用于非金属采矿（如砂石开采）的土地开展连续适配度评分，评分区间为大于0（最低适配水平）至1（最高适配水平）。本数据集基于四项准则地图的加权汇总生成：1）基于矿床规模与数量的产能替代指标值，2）距需求中心的距离，3）距干线公路的距离，4）距铁路或港口的距离。随本数据集附带以下内容：a）连续型非金属采矿适配潜力指数（DPI）的分类版本，b）对应的分类不确定性数据集，c）分析中所用全部准则的详细敏感性分析表，d）分析中所用约束条件与准则的完整说明，包含层次分析法（Analytic Hierarchy Process，AHP）的两两比较矩阵以及通过AHP推导得到的准则权重。
