To view LIVE OpenStreetMap data
add ”?live=true” to the end of your URL, like:
http://cartagen.org/find/sweden?live=true
This will bypass cached data, and will load the most recent edited data from OSM. This is useful for checking your edits on OSM, since openstreetmap.org only regenerates tiles on a weekly basis, as far as I can tell. (Some zoom level DO seem to update, but it’s inconsistent.)
See a full list of modifiers here: Map Modifiers
To embed a map on your site
Use the fullscreen=true parameter in the URL, and put it in an iframe:
<iframe width="600" height="300" src="http://cartagen.org/find/tjornin%20reykjavik?fullscreen=true&gss=http://unterbahn.com/cartagen/natalie.gss"></iframe>
