I was lucky to settle on the 17th floor in apartment with beautiful view of Moscow. First days in apartment my family members spent observing and identifying Moscow skyscrapers visible from our windows. To stop my family members unceasing disputes about surrounding high rise buildings identification I created handbook Moscow skyscrapers and developed this calculator. Using this calculator you can like me identify high sights nearby your observing point. If you are in Moscow, just enter your observing point exact coordinates and height above the sea level. If not - you need to clear and then fill in the sights table.
To identify objects around you, print the bearing protractor created by this calculator, align the protractor mark with the structure that is well known to you, then other objects can be searched in the direction of their pointers marked on the protractor.
