The ArcGIS Desktop software system is the key
means by which groundwater information is compiled
and synthesized in Arc Hydro Groundwater.
However, this is now being supplemented by
ArcGIS Server and ArcGIS Online, by which compiled
Arc Hydro datasets can be published on the
Internet as maps and data services. This emerging
“services-oriented architecture” for geospatial
information is an important way for separate
organizations to publish geographically distributed
groundwater datasets in a manner that facilitates
their assembly and integration over a region.
