The USGS has a KML map of their stream gauges and water quality sensors in the US. Here's a good starting point: http://water.usgs.gov/wateralert/
Getting an embeddable realtime view can be more difficult - I have a regional example here http://www.ce.cmu.edu/~wquest/Dunkard%20Images/SensorMap.html Having worked on a water data research project, there are several standards and data models being discussed and used by researchers. The USGS has shapefiles and IDs of water catchment areas for each major stream - that'll save you a great deal of trouble with DEM terrain data. You don't tend to see these files or stream data online, because the science is mostly done with desktop GIS and rarely publicized. I believe that the NSF, EPA, and local governments were backing http://his.cuahsi.org/ and http://water.epa.gov/scitech/datait/models/basins/index.cfm for sharing information on streams. It would be good to have tie-ins to these successful programs. -- Nick Doiron On Sat, May 28, 2011 at 5:00 AM, Robert Szczepanek <rob...@szczepanek.pl>wrote: > Hi Charlie, > > I like your idea, but there are many issues to discuss. > > 1.
