I want to make my kml files visible for google maps.
I thought about a web service that allows me to upload the file and so it is visible online by direct link.
Is such thing possible?
there's quite a few. I'm fond of dropbox for this - while its primarily a file sync application, using the public folder allows you to give a direct link.
Both the desktop application and web interface work well, and its free for 2gb + some bonus space.
For example, entering
You can click on above the map to get a direct link to that KML loaded in Google Maps, and give people that link if you want them to be able to open the map directly.
