To better understand geographic trends in arsenic occurrence, researchers recently used an interactive visualization technique to link geospatially referenced arsenic concentration information from a water quality database with data contained in digital terrain elevation data (DTED) files. DTED files allow users to develop 3‐D plots of arsenic concentration and topography. The study used the U.S. Geological Survey arsenic point database, which contains water quality data for the United States and its territories. Researchers used technical computing software that allows users to specify subset columns within a graphical user interface.
