How are the Sajama Lines studied?
Tierra Sajama is creating a Geographic Information System (GIS) of the Sajama region for use in mapping and analyzing this cultural landscape. The team is utilizing topographic maps, aerial and satellite imagery, published GIS datasets, and original research to create a spatial database of the Sajama region. Included in this database are a detailed digital elevation model (DEM), several ‘layers’ of archaeological and historic sites, vegetative land cover grids, natural features such as rivers and lakes, towns and man-made structures, and, of course, the Sajama Lines themselves. It is the team’s hope that this data will one day be field verified, and that new data will be added, by using a Global Positioning System (GPS). In addition to mapping and spatial analysis, the Tierra Sajama team has also done extensive searches of the archaeological, historical, ethnographic and natural history literature of the region. The team has found valuable information relevant to the study because the
