Weight of Evidence Geospatial Analysis and Potential Locations of Ancient Gold Mining Settlements in Benguet in the 16th and 18th Centuries

Abstract:

Using the Weight of Evidence method in the analysis of geographic patterns, this paper sought to identify areas with high probability for being ancient settlement locations of small- scale subsistence gold miners in Benguet Province of Northwestern Luzon between the 16th to the 18th centuries. The training points used in this project include 24 known ancient village locations that are based on Spanish missionary accounts in the 18th century. The evidential themes that were used include: 1) distance from gold placer mines, 2) Slope class, and 3) Land-use class. Incidentally, the distance to placer mines is the same as distance to fresh water source for habitation purposes. The resulting response theme or unique conditions map shows areas that may potentially contain archaeological sites. The final map shows areas where there is a high probability of encountering an archaeological site.
