What hospitals are there in East-Berlin? We then return all hospitals, the longitude of which is greater than the longitude of the Brandenburg Gate. The issue with that is that some Berlin hospitals miss a coordinate location and those will be left out from the results. ]5[To retrieve the hospitals from the eastern parts of Berlin, we can filter for hospitals’ coordinate location, then compare its longitude parameter to the center of Berlin. As Berlin’s center we have chosen its historical center at the Brandenburg Gate, which is located at latitude 52.516266, longitude 13.377775.
