Link to URL datasource

Finder can register data source URL's from the internet or a network. This allows users to define data sources that will be continually updated, aggregated and archived in GeoCommons.

To register a datasource, provide the URL to a file type that is supported in GeoCommons and POST using the overlay[wild_url] parameter to /overlays.xml.

curl -i -X POST -u "yourusername:yourpassword"  -d "overlay[wild_url]=http://earthquake.usgs.gov/eqcenter/catalogs/1day-M2.5.xml" http://finder.geocommons.com/overlays.xml


URL's can only be registered once in GeoCommons. So if the URL has already been registered by a user, you will receive a redirect to this existing Overlay. You can make a copy of that overlay if you want to modify the metadata.
