Creating administrative polygons by joining village lands
The Ottoman administrative polygons (kazas and nahiyes) are the principal analytic resolution used in PPOGEO_BG. The lack of reliable administrative maps for the Ottoman era forced the project to create its own polygons by spatial join of administratively attributed points from the Ottoman population registers and modern village land polygons.

Filibe district (kaza) in 1840s
The Ottoman population registers contain point (settlement) data, including point’s administrative belonging at the level of district and sub-district.

The map displays the district (kaza) of Filibe (Plovdiv) and its sub-districts (nahiye) of Koyun tepesi, Göpsu, Karacadağ, Konuş, and Rupçoz.
