Map of Ukraine's Primary Grain Export Facilities
No guarantees here, but I believe this map represents Ukraine's primary grain export facilities. You can use this link to view the satellite image in a Google Map of the Elevators.
This map shows what appear to be six unique grain export elevator sites in three different Black Sea port sites; Odessa, Yuzhne, & Nikolaev. One of the Nikolaev sites looks a bit more like a fertilizer transfer and storage facility.
