The Analysis of Settlement Patterns of Iron Age in Piranshahr Plain Relying on Geographic Information System (GIS)

Interpretation of human’s old behaviors in the past and paying attention to complex and interactive processes between humans and the environment to be understood in terms of their dependence on the components of the natural and ecological environment is the center of modern archaeology’s attention.  Archaeological surveys and analysis of settlement patterns are considered well-known methods in archaeology to help identify these interactive processes.With the studies of the Archaeological Board of the University of Pennsylvania on Hasanlu Hill and the Sandus Plain, the southern basin of Lake Urmia became one of the most important archaeological sites and a basis for chronology in northwestern Iran. Meanwhile, Piranshahr plain on one hand due to its proximity toHasanlu area in the north and Rabat area in the south and on the other hand due to the neighborhood of this area with great powers such as Assyria, Urartu and Mana in the first half of the first millennium BC, Is one of the important areas in terms of archaeological studies of the Iron Age in northwestern Iran. This study examined the Piranshahr plain, assuming that the Iron Age settlements of the Piranshahr plain follow a specific settlement pattern. In this research, using field and library studies and geographical analysis models, a methodical and appropriate interpretation of the distribution of Iron Age areas and the first millennium BCPiranshahr plain was presented. Studies have shown that the Iron Age settlements in the region are most affected by two geographical factors, altitude from sea surface and access to rivers, and this has led to the creation of linear networks in the course of rivers resulting to a suitable choice of height relating to the plain. It was also found that the Iron Age settlements of this plain, following the shape of the roughness and natural geography of the region in the first half of the first millennium BC, by creating a specific settlement hierarchy, tended to form an independent local political unit. The existence of this political unit in modern Assyrian writings as Xubuskie could be identified.
