Document purpose of latitudeDelta and longitudeDelta

[bbodenmiller]

Would be nice if https://github.com/airbnb/react-native-maps/blob/master/docs/mapview.md or similar documented the purpose of latitudeDelta and longitudeDelta.

I had to look this up too. It allows you to control how much of the map to display. In effect, the amount of "zoom".

latitudeDelta
The amount of north-to-south distance (measured in degrees) to display on the map. Unlike longitudinal distances, which vary based on the latitude, one degree of latitude is always approximately 111 kilometers (69 miles).

Why was this closed? I do not see the properties reflected on the documentation still.

Do you expect every user to google and come to this issue to look it up?

... what?

There is no mention of latitudeDelta or longitudeDelta in whatever you linked.

At this point I am very confused and convinced that this issue should be re-opened.

Got it.

I supposed you meant to link this instead :
