 Comparing GIS Data Types Within the Arc Hydro Data Model Track: Water Resources Author(s): Elisabetta DeGironimo The advent of an object-oriented GIS data model has facilitated the use of spatiotemporal hydrological event data. This paper presents the results of a master's thesis entitled "Spatiotemporal Queries of Hydrologic Event Data: A Comparison of GIS Data Types." The objective of this thesis study was to determine if there is a computational advantage to using a geodatabase based on the Arc Hydro data model over the coverage or shapefile data types using ArcGIS software. In order to determine if there was a computational advantage to the geodatabase, thirty queries were constructed and programmed in Visual Basic for Applications and run independently of user intervention against the three data types.
