Google maps api for satellite view

You can use the geocoding api from Google.

https://developers.google.com/maps/documentation/geocoding/intro#GeocodingResponses

The geometry section should help you

"geometry" : {
            "location" : {
               "lat" : 37.4224764,
               "lng" : -122.0842499
            },
            "location_type" : "ROOFTOP",
            "viewport" : {
               "northeast" : {
                  "lat" : 37.4238253802915,
                  "lng" : -122.0829009197085
               },
               "southwest" : {
                  "lat" : 37.4211274197085,
                  "lng" : -122.0855988802915
               }
            }
         },

You can calcute the area from the difference between the northeast and southwest long/lat in viewport

var map = new google.maps.Map(document.getElementById('map'), {
    center: {lat: 36.964, lng: -122.015},
    mapTypeId: 'satellite'
  });

Sure, you'd query the api to get the coordinates, and when you create the map you just set mapTypeId to 'satellite' https://developers.google.com/maps/documentation/javascript/maptypes
