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.
