Hello @pidugu konda reddy,

As your response is exactly a copy paste from the another changeset we refer, i guess you are also working for Uber. 

Are you aware of this : https://osmfoundation.org/wiki/Organised_Editing_Guidelines I can't find the documentation on the OSM wiki about your organised edits. Can you provide us that and if not regulize the situation ? 

For the edit itself : 

Can you clarified witch website you reffer ?  You mentionned you don't copy it but you realy play on words ...
So how do you have determine the levels of footway, steps, elevator etc ? 
Also for this object (for exemple) https://www.openstreetmap.org/way/1266853802 how do you determine the orientation and globaly the position inside the terminal ? 

Thanks in advance for your responses,
Have a good day.
