I would like to build a site that is based on google maps. See links below for examples. I have a custom google earth layer, so content is not the issue. The problem is I am a total newcomer the site building. I have done some stuff on Weebly.com and that's it. I can figure this out once I know what to research, just need pointed in the right direction. Is this a particular type of site? (flash, html5). Are there templates that will work on a Wix.com or Weebly.com to do something like this? http://sna.pr/ http://trendsmap.com/ http://www.culinaryculture.com/map If this has been addressed in this forum already, my bad, a quick forum search didn't turn up results.
