The zoom level is not very close in with the satellite view as compared to standard view and it changes day to day?

I use iCoud at tmes as a locator to find out where my child is. His iPhone 4s is registered anmd I sign in to iCoud under his id and pw. When I first startred using the app I could zoom in very close in any mode-standard, satellite and hybrid and all zoom levels were relative to each other. Lately I can get the standard mode to zoom very close but the other 2 satellite views are not coming in very close. If I zoom all the way in with standard mode I can then click on satellite and sometimes it will stay zoomed in close but most often it backs out a few levels. Is there something I am missing?
