DataSlate is an easy-to-use Java-language computer program for displaying coregistered raster images representing large sets of data. The program includes a main viewing module that can display image data that have been converted into a special DataSlate format called "SimpleStruct" by use of an Interactive Data Language program called "SimpleGen." The conversion into SimpleStruct optimizes the organization of the data in the sense that it simplifies any computations that must be done subsequently during perusal of the data. DataSlate enables the user to navigate very large sets of scientific data visually: DataSlate presents a slatelike user interface with simple buttons to select sets of data or to zoom in or out. The user can scroll through a set of data by simply dragging a cursor on a screen. DataSlate can also dynamically load plug-in software tools (e.g., for measuring lengths, angles, areas, or geographic coordinates) at run time. DataSlate can also traverse coregistered collections of data and can present a second data channel in a window on the screen to facilitate correlation or comparison of two sets of data (e.g., from two sensors and/or taken at different times).
