Space-Time Analysis of the WRAP Model with a Focus on Data VisualizationClark D. Siler, M.S.E., David R. Maidment, Ph.D. ABSTRACT The Water Rights Analysis Package (WRAP) is Texas’ official water availability model. The output of this computer simulation is a voluminous, structured text file. In its native format, the output file cannot be exposed to geographic information system (GIS) software due to inconsistent formatting between the file’s sections. This thesis presents a space-time analysis of the WRAP model and its output while focusing on making the output data available for visualization in a GIS. This analysis reveals that the temporal and spatial nature of the data make possible the display of output data as color-coded maps which can show spatial relationships between data, as well as time series graphs which are useful in revealing temporal trends and events for locations. This visualization is made possible through repackaging the output data from its native format to a set of multivariable geodatabase tables. The means of these forms of visualization are automated through the use of the WRAP Display Tool. This tool was developed specifically for the WRAP output data for use in revealing the maps and time series mentioned.
