17.5.2 Direct Access
the Grand Travers Bay Watershed on the north-
west of Michigan's lower peninsula maintains
an Interactive Maps website that includes maps
on public lands, wetlands, watershed bounda-
ries, water quality monitoring locations and
erosion potential (http://www.gtbay.org/maps.
asp). The US Department of Agriculture Natural
Resources Conservation Service (NRCS) has a
website with maps (in Adobe Portable Document
Format) and charts developed using National
Resource Inventory (NRI) data (http://soils.
usda.gov/use/). NRCS also has information
on world soil resources including maps on
erosion.
Direct Access (also called Direct Read) refers to
applications that allow users to view erosion
modelling results directly using a web browser.
Non-profit organizations provide erosion poten-
tial or vulnerability maps, using a map server,
as part of watershed information portals.
For example, the Arizona Nonpoint Education
for Municipal Officials program (AZNEMO)
provides erosion potential in their watershed-
based plans that cover Arizona. The erosion
potential maps are used to identify watersheds
at risk for water quality impairment (http://
arizonanemo.org). The Watershed Center in
