如何在Google地图预览（新版GM）中计算缩放网址参数？ [英] How to calculate zoom URL parameter at the Google Maps Preview (new version GM)?

问题描述

但是，在新的谷歌地图预览中，我不能给链接becouse我可以' t计算新的缩放参数。

例如，新的Google地图网址：

https：// www .google.co.uk / maps / place / @ 29.6765085,59.868445,11z

I need to write chrome extension which references on new version of Google Maps site.

BUT, in new google maps preview i can not give link becouse i can't calculate new zoom parameter.

For example, URL new google maps: https://www.google.com/maps/preview#!data=!1m4!1m3!1d4112402!2d-62.7728736!3d44.829016

new zoom parameter are very strange:

zoom 23 http://google.com/maps/preview#!data=!1m4!1m3!1d 1145       !2d29.6765085!3d59.868445

intuitive and easy                              how to calculate it?

This parameter depends on coordinates!

How can i generate link on new google maps with this zoom, if i know old zoom parameter (from 1 to 23)?

I think I need a new weird setting for a new function Globe... but i don't know how to compute this... google search don't know answer

If zoom parameter is bad - maps redirect to home location.

解决方案

How about using the alternative @ syntax when linking to the maps?

Template:

https://www.google.co.uk/maps/place/@{LATITUDE},{LONGITUDE},{ZOOM}z

Example:

https://www.google.co.uk/maps/place/@29.6765085,59.868445,12z https://www.google.co.uk/maps/place/@29.6765085,59.868445,11z
