2004 UC Proceedings Abstract
 Development of GIS-Based Stream Flow Data Analysis System for Turkey Track: Water Resources Author(s): Serkan Girgin, Nurunnisa Usul, Zuhal Akyurek Data visualization and analysis tools constitute an important part of today's water resources protection, development, and management studies. GIS has been very widely used in the last decades. U.S. EPA's BASINS and European Union's GREAT-ER systems are sound examples of latest developments in GIS-based systems. Although located at water critical geo-political location and has many on-going and planned water resources related projects, Turkey still has neither national hydrography datasets nor local water quality/quantity data analysis tools. In this study, a GIS-based data visualization and analysis system has been developed for stream flow data collected in Turkey. The system developed using Avenue scripting language of ArcView 3.2, features a graphical user interface that utilizes dialogs, tables and charts to interact with the user and visualize stored data. A number of spatial and statistical analysis tools are also made available to reveal trends in data, calculate summaries and create thematic maps.
