本文旨在探討如何藉由公眾參與地理資訊系統進行原住民族傳統領域調查，以達到原住民族賦權的目的。本文藉由利用地理資訊促進原住民族參與傳統領域調查與整合傳統知識，並針對參與人員與調查過程進行參與觀察與深度訪談，分析地理資訊科技對於原住民的賦權與邊緣化的影響。從泰雅族司馬庫斯案例研究中，本文發現運用公眾參與地理資訊系統可有效進行傳統領域調查，促進司馬庫斯部落在自覺、參與、能力與資源上的賦權。

This paper discusses how to apply public participation geographic information system (PPGIS) to survey the traditional territories of the indigenous peoples and to empower the indigenous peoples. This study used GIS technology to promote local participation and to integrate the traditional knowledge of the aboriginal communities in surveying traditional territories. This study also achieved two other objectives. First, by connecting the local context and applying GIS technology to prepare the geographic data, we were able to conduct a training program of community mapping for the people of the Smangus community. Second, we were able to assess the impact of PPGIS on the empowerment and marginality of the indigenous peoples at the scales of community and ethnic group. The usefulness and limitation of PPGIS are also highlighted in this paper.
