Predictive Model of the Balatok- Tonglo- Aringay Gold Trade Trail in Southwestern Cordillera [Research Note]

Abstract:

Using the Least Cost Path method in raster GIS analysis, a predictive model was created to estimate the location of an ancient gold trail connecting the Balatok/ Acupan mines with Tonglo gold bulking center and Aringay coastal settlement within Benguet and La Union Provinces. To derive the model, ASTER global digital elevation model was used in tandem with WorldView2 multispectral and high resolution imagery. The paper shows that GIS and Remote Sensing methods immensely aid in delimiting the research study area in the search for trails thereby resulting to efficient targeting of time and resources for second order excavations.
