Water and Climate (W&C) Data Management and
Analysis Requirements
• W&C data is spatial.
• W&C data is temporal (time series &
simulations).
• W&C data is highly interrelated and can be
very large.
• W&C data need to be accessed by a diverse
and geographically dispersed groups of
users.
Does Geographic Information System (GIS) fulfill
these requirements?
• GIS was developed to provide a spatial context to
information.
• GIS is based on the relational database
approach.
• GIS provides a flexible, intuitive and visual
interface to manage and analyze data.
• GIS platforms are increasingly network oriented.
• GIS does not address temporal data adequately.
Arc Hydro
• Arc Hydro is an ArcGIS database model
designed to manage and analyze water
resources data.
• Arc Hydro handles both spatial and temporal data
• Contains several tools for hydrologic analysis,
time series analysis, river networking and
groundwater modeling.

Online access & sharing of data
• GIS portals offer visual and intuitive interfaces to
access GIS data.
• Geoportal Server technology by ESRI (Environmental
Systems Research Institute).
• Examples of ESRI Geoportal sites:
– NOAA’s North American Drought Monitor
– CUAHSI (Consortium of Universities for the
Advancement of Hydrologic Science) Hydrologic Data
