Good Day !!!

You are invited to join "Yahoo! Groups - archydro" (ArcGIS -
Geographical Information System). This group aims to provide a forum
for exchange of ideas and experiences regarding application of GIS in
Hydrology and Water Resources; and use of ArcGIS software (in
general) and Arc Hydro (in particular).

Geographical Information Systems (GIS) are used to display,
manipulate and analyse spatial (map) data. ArcGIS (produced by ESRI)
is an integrated collection of software products for building a
complete geographic information system (GIS). There are three ArcGIS
desktop applications - ArcCatalog, ArcMap, and ArcToolbox. ArcCatalog
is the application for managing your spatial data holdings, for
managing your database designs, and for recording and viewing
metadata. ArcMap is used for all mapping and editing tasks, as well
as for map-based analysis. ArcToolbox is used for data conversion and
geoprocessing. Using these three applications together, you can
perform any GIS task, simple to advanced, including mapping, data
management, geographic analysis, data editing, and geoprocessing.
There are also server-based ArcGIS products, as well as ArcGIS
products for PDAs. Extensions can be purchased separately to increase
the functionality of ArcGIS.

GIS is a powerful tool for developing solutions for water resources
such as assessing water quality and managing water resources on a
local or regional scale. Hydrologists use GIS technology to integrate
various data and applications into one, manageable system. ArcGIS
with Arc Hydro gives you the flexibility to combine watershed
datasets from one map source with stream and river networks. The
suite of tools contained in Arc Hydro facilitate the creation,
manipulation, and display of hydro features and objects within the
ArcGIS environment. Use ArcGIS Spatial Analyst for hydrologic
analysis such as calculating flow across an elevation surface, which
provides the basis for creating stream networks and watersheds;
calculating flow path length; and assigning stream orders.
