According to OpenStreetMap , Turkish territorial waters in Aegean Sea was determined by Greek Hydrographic Organization. 
Due to the fact that In Aegean Sea , there are a lot of uncertain islands, islets and cliffs called grey regions that not determined in Lozan Convention, this status leads to many diplomatic Crises between Turkey and Greek Government because there regions are not decided who belongs to. 
Kardak (Imia) islands in vicinity of position ( 37 02.807 N - 027 08.950 E) are one of the these uncertain islands. However, Kardak (Imia) islands was shown in Greek Territorial waters in your chart. Republic of Turkey accepts or supports the idea that these regions in Aegean Sea inherit from Ottoman Empire because these areas was not given to Greek Government in accordance wlth Lozan Treaty Convention . 
Taking everything into account , Kardak (Imia) islands were shown in Greek Territorial waters in OpenStreetMap . This situation was fault as Lozan Convention.

According to the Turkish view , means that 
The sovereignty over an unkown and number of small islets and rocks in the Dodecanese may be still undefined . Also, Kardak/Imia is one of the these undefined islets, islands. Also According to the 6 ,12 ,15 and 16 articles of the Lausanne(Lozan) Treaty Convention, Kardak/Imia was not defined or contained as one of the Dodecanese Islands and who belongs to. 
Because of that , Kardak(Imia) should be not shown in Greek Territorial Waters. This area should be shown as an uncertain area for political reasons in OpenStreetMap 
I kindly would you like to review this situation.
