Willamette Basin Explorer, a subset of Oregon Explorer, is a digital library containing numerous tools for policy makers and community members managing land and water resources in the Willamette Valley.  One of these tools, the advanced mapping tool, allows resource managers to create unique maps of the basin without requiring GIS software.  The advanced mapping tool provides open access to GIS data throughout the Willamette Basin.  GIS layers available in Willamette Explorer include: past and present land use and land cover, restoration and conservation opportunities, floodplain restoration, historic floods and water quality.  Willamette Explorer also uses models to project three future scenarios in the Willamette Basin: conservation trend, development trend and plan trend.  These three scenarios predict the impact that land use will have on natural resources in the Willamette Basin.  Resource managers interested in river restoration can use Willamette Basin Explorer to identify restoration opportunities which are both ecologically and socially feasible.
