Ancient Trails of the Surigao Gold District: A Preliminary Baseline Predictive Model

The paper will present a macroscale baseline model of possible ancient trails connecting Jabonga- Kitcharao and Placer to the Balangay sites in Butuan utilizing geographic information systems (GIS) analysis of digital elevation models (DEM). The paper also taps into available natural band combinations and infrared band combination imageries to further provide the mesoscale context of the sites. This baseline data may be used in a secondary analysis that will involve tapping on a multiscalar method that will utilize enhanced macro scale satellite data, mesoscale and microscale remotely piloted aerial systems (RPAS) data, and ground-truthed data.
