Answer 1

In my apps I used these methods:

First - it's good to have a default position (for example - application is about a city - then zoom in to show whole city) (on first - first app opening, when no data downloaded)

Second - if user has already used map - can store his coordinates, and show those (+ span(zoom) level) in case there are no other data available.

Third - in case of data:

1.) If database has already some coordinates - on first map opening (when application has been closed) - zoom out/in to show all pins on map.

2.) When still in map and just arrived updates (new locations or changed something), there are two possibilities :

2.1.) If user has not zoomed in to any location - map zooms in/out to show all locations.

2.2.) if user has zoomed in - locations are updated, but map doesnt zoom out

Ofcourse - then there are also some filter buttons (for example : search, user location, and some more - which filters locations, and zooms out/in to show filtered results)
