Since 2010, the IEM has been archiving Iowa DOT Roadway Weather Information System (RWIS) webcam imagery. Most of the RWIS stations have a webcam that take a suite of static views at ad-hoc time intervals. Up until now, the IEM only had this clunky interface as a means to view this archive.
This is powered by a IEM Web Service that emits a GeoJSON with links to the archive.
Hopefully folks find this useful and please keep feedback/ideas coming my way!
