Specific zoom in Google Maps

Question

I have a Gmap that has to zoom in bit by bit. To achieve this I need the Google map zoom level to be formatted like this '4.001'. I tried doing this by simply add this value as zoom level but it doesn't work.

So my question is how to achieve a Google map zoom level using multiple numbers behind the decimal. Is it even possible? If not, how do I achieve the slowly precise zooming?

Thanks

Answer 1

According to the documentation, the zoom level corresponds to the number of tiles in which the Earth is divided:

zoom = 1   =>   tiles = 2^1 * 2^1 = 2 * 2 = 4
zoom = 2   =>   tiles = 2^2 * 2^2 = 4 * 4 = 16
zoom = 3   =>   tiles = 2^3 * 2^3 = 8 * 8 = 64
etc

Increasing the zoom level by 1 doubles the level of detail. The zoom level is an integer value. It corresponds to the discrete value of the slider control on Google maps.

Answer 2

When you want a zoom level between 4 and 5 for example 4.2 or 4.3 the only way is to use a cluster algorithm because the map is subdivide by 4. Cluster means that when the tiles are so close together that's not anymore practical to show them. There is a for example marker manager that can calculate clusters but it's not applicable to the map because it doesn't make sense to subdivide by 6 or 7 tiles.
