Field Testing ARC GRID-Based Archaeological Probability Models in Jordan

"Archaeology at Tall al-Umayri, Jordan, has revealed a mixed picture of settlement during the Iron Age I period. Excavation at Umayri revealed a heavily fortified urban center, while the hinterland survey found few contemporary supporting sites. Accordingly, the 2000 field survey concentrated on a directed search for additional Iron Age I sites. This search was guided by a predictive model created in ArcInfo software''s ARC GRID extension and increased the number of Iron Age I sites by 75 percent. This report will discuss the creation of the model, how the model was tested in the field, and the results of the test."
