Big news on May 28th when Google released a Plug-in which makes it possible to view Google Earth, including 3-D buildings and KML files in a browser window, without downloading the full version. Very much excitement about this, and there will certainly be some great applications very quickly. Exploring this topic, an interesting application for US boaters surfaced. EarthNC is a low-cost application/service which allow the user to add all kinds of water charts for US coastal and inland waters to Google Earth — online or offline. It looks amazing (though I don’t have any charting know-how), and appears to have been enthusiastically received. Hope to hear back from them about whether a Dutch / European version is on the way.
This same developer (EarthNC) has just released an online converter which allows you to create Google Earth Plug-in code with your own KML files or MyMaps URLs, which can then be embedded in your website. TakeItWithMe for Embedded Earth is in “Beta” form, but works handily (Not any more).
Update 17/6/2018: EarthNC viewer will be taken offline within 6-12 months.
TakeItWithMe no longer functions.
