Our company, Mountain Visions, helped produce an Interactive Watershed web site project on the Potomac and Shenandoah Rivers. One of the locations where we produced a 360 degree panorama and a video sequence describing the construction of a Rain Garden project being built at the Blue River Ridge Community College. There are additional links to other web sites that contain Rain Garden information.
Below is a link to the panorama page. The video sequence is a hot spot you can open by finding and clicking on it in the panorama. I will include the video page link as well.
There are many additional interactive maps, 360 degree panoramas and video sequences on the "Resource Issues' section of the Potomac Watershed web site.
From 2000 to 2003, we also produced 4 other similar Interactive Watersheds Web sites across America. Below is a link to a U.S. map where you can visit each one.
