Bulked gold, riverine trade, hiking trails, and WorldView2 satellite remote sensing in Northwestern Luzon: The Angaqui network

Abstract

This paper is based on a case study of the Angaqui gold trade network in Northwestern Luzon during the Early Historical to Historical Period (10th to early 20th c). Multiple data sources including GIS predictive modelling and remote sensing through high-resolution and multispectral WorldView2 satellite imagery, written primary historical and secondary historical sources, indigenous peoples oral tradition, and results of systematic archaeological survey and excavation were integrated in the research to come close to a wholistic view. Availability of the satellite imagery facilitates a more regional and multi-scalar approach to archaeology of the region. Remote sensing has revealed segments of old trails within the network. The written and oral tradition both complement each other when correlated with available archaeological data. Availability of historical visual documentation also provides a means to reconstructing the gold evanescent market encounter in Northwestern Luzo
