This document provides an overview of the Hydrologic Information System (HIS) and the HydroDesktop application. It describes how HIS functions as a web service to provide access to hydrologic data through standardized tools and procedures. HydroDesktop is presented as a client application that utilizes HIS web services and MapWindow GIS components to allow users to search for, download, display and analyze hydrologic time series data. The document outlines key capabilities of HydroDesktop such as data search, download, time series viewing and plug-in development.
