Google Maps default zoom level

I created a public map using my Google Map. I want to set a default zoom level, but it is not save开发者_高级运维d. Is this possible? Also, is it possible to change the list of place markers?

the reference map that you supply (quebec summer festival) is called by the URL: http://maps.google.com/maps/ms?source=embed&hl=en&geocode=&ie=UTF8&msa=0&msid=112492115201367239282.0004609e0fcc239c4f792&ll=46.81084,-71.217113&spn=0.02056,0.038624&z=15

notice that the last parameter "&z=15" defines the zoom level (in the embed map code, "&z=15" becomes "& a m p ; z = 1 5" [remove spaces between letters]). if you change this you can increase or decrease the zoom level. if you suppress the zoom level, googlemaps will automatically calculate a zoom level when displaying said map. NORMALLY this leaves some of your map outside the frame.

so, just by supplying the URL with the desired zoomlevel you have solved your problem. this works very well with static maps. if you have a dynamically generated map (from a database, for example), the fastest solution is to put 2 markers (top left and bottom right corners) slightly outside your boundary box. this will force automatic zoom in the desired amount (hopefully).

Not using API just made a map points using my GMail account and made it public, like the following site: http://maps.google.com/maps/ms?source=embed&hl=en&geocode=&ie=UTF8&msa=0&msid=112492115201367239282.0004609e0fcc239c4f792&ll=46.81084,-71.217113&spn=0.02056,0.038624&z=15

Nothing is saved by a web page. HTML browsing is stateless. If you want to save some information you will need to use similar trick as any other web applications. E.g. putting it in cookie and the setting the zoom level using the information in the cookie when you initial the page.
