How to set zoom in corona sdk mapView

Question

Answer 1

myMap:setRegion( 3.234542, -12.123456, 0.01, 0.01 )

The last two arguments of the above function is together called the span of the mapview . Induvidually they are longitudedelta and latitudedelta (longitudeSpan/latitudeSpan). They represent how many degrees of longitude and latitude that should be visible on your mapviw.

Consequently, Setting them both to 1 will cause your mapview to display 1 degree across and 1 degree from top to bottom of the map.

Increase long/latDelta --> further from ground

Decrease --> closer to ground

Answer 2

Please try this

local myMap = native.newMapView( 0, 0, display.contentWidth, display.contentHeight )
myMap:setCenter( 37.331692, -122.030456, 0.01, 0.01 )
