How does Google Maps determine city center?
This is determined by searching a city first, zooming into where the red pinpoint icon is, and dropping that omnipresent orange dude onto the closest corner. The results, although not entirely accurate, actually can give a good depiction of what the image if the city portrays.
Which method is used to get the current zoom level of the map?
getZoom() method
The getZoom() method returns the current zoom level of the map.
Where is the Centre of a city?
A city centre is the area of a city where significant commerce, political, cultural and power is concentrated. It is often also the geographic centre of a city. Typically, the city centre will be the first part of a city that was settled, making it the most historic area.
How is the center of a city determined?
Though, for some location based engines such as job search, the center of city are chosen based on many factors, including distance to the city boundary, population, economy etc.
Which is called heart of the city?
The correct answer is Central Business District. Central Business District is the Heart of the City. Central Business District is referred to as CBD. CBD is the first ring of the concentric zone model.
What’s the maximum zoom level in Google Maps?
The return value is the maximum zoom level that will still display the entire bounds. This value will be between 0 and the maximum zoom level, inclusive. The maximum zoom level is 21. (I believe it was only 19 for Google Maps API v2.) Google Maps uses a Mercator projection.
How to calculate the zoom level for a given bounds?
A similar question has been asked on the Google group: http://groups.google.com/group/google-maps-js-api-v3/browse_thread/thread/e6448fc197c3c892 The zoom levels are discrete, with the scale doubling in each step.
How to calculate the zoom level for a latitude?
A complete solution should calculate the zoom level needed for latitude and the zoom level needed for longitude, and then take the smaller (further out) of the two. The “bounds” parameter value should be a google.maps.LatLngBounds object.
Are there latitudes above 85 degrees on Google Maps?
A Google Maps map, however, does not show latitudes above approximately 85 degrees North or below approximately -85 degrees South. ( reference) (I calculate the actual cutoff at +/-85.05112877980658 degrees.) This makes the calculation of the fractions for the bounds more complicated for latitude than for longitude.
