Settlement mounds of the Near East
“tells”: Arbil / Iraq topKonya Plain / Turkey right
Arbil
Mapping tells
• accurate, supra-regional data sets
• guidance in local survey
• objective search criteria by RS “Archaeological distribution-maps are maps of the distribution of archaeologists.”Western Khabur plain
ASPRO

Digital elevation model
• Training data set from CORONA & ground survey
• DEM patches of tell sites and “background” sites
[Ur J, Wilkinson T]
Digital elevation model
Binary classifier:
• Learn set of linear “Eigen”-filter
• Nonlinear classifier on Eigenspaces

Binary classifier:
(independent of season)• classify each ASTER
image individually• fuse result maps &
pool decisions
