Stone Piles

Stone Piles
Either in linear or non-linear piles
within field parcels or along field
parcel boundaries. Their
permanency is uncertain, some
seem to have been present for
years, others seem to be in the
process of removal, to permanent
dump sites off the agricultural land.

Acquisition of DOP
Orthophotos production is organized into a maps index consisting of 67 Aerial Triangulation units for aero-
photogrammetry works called AT blocks. AT blocks are obtained dividing the seven TM Zones in a 1.5 degree
Longitude and 1.0 degree Latitude rectangles, covering the whole Turkey.

GCP measurements for the South-Eastern area of Turkey for Blocks K5, L5, M4 and M5 are
not progressing due to security issues in the area. The only option might be to utilize
existing 1:25,000 topographic maps if no field works can be performed.
