sets making it very difficult to validate and assess the data source and its quality.
The development of the spatial database is a continuing process. Feedback from
users of the ArcIMS web based viewer is helpful in managing the website in order
to make it more user friendly. Efforts continue in the updating of data sets with
current information.
In early 2007 a survey was sent to 188 current and potential users of the Maumee
Basin GIS/Remote Sensing project website (
www.maumee.utoledo.edu
) in order to
assess the utility of the website and ArcIMS data viewer and to solicit feedback on
future additions and improvements (see Rousseau, this volume for more details).
A total of 55 individuals responded (29% return rate) with state and federal
government agencies and NGOs/Universities having the largest number of resp-
onders. Over 41% of respondents indicated that they had been using GIS for more
than 5 years. When asked about their use of GIS in watershed planning 60%
indicated that they had created maps or data products and the most common sources
of GIS data that they used included the Ohio Department of Natural Resources
(ODNR) GIMS website, USGS, and NRCS Service Data Gateway. In accessing and
using the Maumee Basin GIS/Remote Sensing project website over 90% rated the
site as Good to Excellent and suggested improvements, including making more data
readily available for download, providing clearer instructions for non GIS users,
and providing links to metadata and source citation.
