As data collection technologies advance, almost ev ery eld of scienti c research sees an increase in the amount and frequency of data that can be collected. In many cases, the rst best method for preprocess ing two and three dimensional data sets is to exam ine them visually, using some sort of plotting soft ware. Although display technology is advancing and monitors are becoming available with increasing reso lutions, this increase in available resolution does not necessarily match the rapid increase in data collec tion. This mismatch leaves researchers with only three choices for visual processing: to view the data in many small chunks, to view only a representative subset of the data, or to create a custom display for viewing much larger data sets at higher resolutions. This pa per discusses one method of full lling the third option. The process used here is to create a customized dis play using nine consumer level monitors mounted in a three by three con guration resulting in a display with nine times the resolution of a single monitor. A custom viewing environment is also developed within this project that is designed to lend itself better to the tiled display than would an existing three dimensional data visualization application. The data used for this project consists of a large set of Oceanographic sensor readings taken from several deployments throughout the Gulf of Maine.
