The research started by reviewing the use of web GIS by Aboriginal communities, governmental agencies and the private sector for aboriginal resource management. It then reviewed the current trends of web GIS technologies. This included a comparison of two commercial software ESRI ArcIMS and Intergraph Geomedia Webmap. ESRI ArcIMS was chosen to develop the prototype because of its easy maintenance and customization. In this research, the Yukon Territory, comprising 14 First Nations, was selected as the study area. Data for the Yukon First Nations was collected, edited, processed. A database was then designed and populated, and a web GIS prototype was developed.
