             RiverTools 3.0, Service Pack 3 Release Notes
    --------------------------------------------------------------

    Introduction:

    We very much appreciate receiving information from our
    customers regarding bugs and requests for new features.
    If you think you have discovered a bug, please send e-mail
    to support@rivix.com and describe the problem in as much
    detail as possible.  Service Packs with fixed bugs and new
    features are released periodically on our Downloads page at
    www.rivix.com.

    ---------------------------------------------------------------

    New Features:

    (1) Added a Tools menu to windows created by the Display >
        Grid Sequence dialog that includes new Time Profile,
        Line Profile and Animated Profile tools.  The Time Profile
        tool can plot how grid values for a selected pixel change
        over time using values in an RTS (RiverTools Sequence)
        file.  For example, this tool can be used to create
        hydrographs from an RTS file that contains spatial
        discharge values.

        The Animated Profile tool lets you select a streamline by
        clicking in the display window, in the same manner as the
        standard Channel Profile tool.  Values in the current frame
        of the RTS file are then plotted as a function of distance
        along this streamline.  You can also plot the profiles for
        all subsequent frames as an animation.  As an example, this
        can be used to animate flood waves moving downstream, as
        when the RTS file contains spatial discharge values from a
        hydrologic model.  Several options are included in the
        Options menu.  
 
    (2) Added "Save as AVI Movie" option to the Options menu of
        the Display > Grid Sequence dialog and to the Options
        menu of the Animated Profile tool.  This allows animations
        to be saved in AVI (Windows Video) format.
 
    (3) Improvements to the Display > Function dialog, including
        the ability to specify xmin, xmax, ymin, & ymax.

    (4) Added the Select Grid entry to the Options menu of the
        Line Profile tool's window.  This option already existed
        for the Channel Profile tool.

    (5) Improved the XObjView tool in the Tools menu.

    (6) Added the ability to specify a vertical exaggeration
        factor (Z Scale Factor) in the Relief Zoom tool.

    (7) Added 2 new tool window cursor types, including Circle
        Only and Cross Only.  These are accessed via the File >
        Set Preferences dialog, in the Window Tools panel.
        Their size depends on the array sizes in the same panel.

    Fixed Bugs:

    (1) Fixed a bug that affected flow grids created for DEMs
        with predominantly negative elevation values, as is
        common for Mars MOLA DEMs and bathymetric DEMs.  This
        bug caused depressions to be "over-filled" so that
        flow directions were not always accurate.

    (2) Fixed a bug that caused contributing areas computed
        via the Mass Flux method to be set to NaN in some flat
        valley bottoms.

    (3) Fixed a bug that prevented the use of blank spaces in
        some RiverTools file and folder names.

    (4) Fixed a bug that required byte order to be specifed
        in the header of imported ARC Gridded ASCII files in
        order for their RTI files to be correct.

    (5) Fixed a bug in the Value Zoom dialog that prevented
        jumping to the specified X and Y coordinates in some
        cases.  Expanded this "Jump" feature to handle more
        coordinate types.

    (6) Fixed a bug that prevented the Save Window option
        from working for DEM Patching Preview windows created
        with the Prepare > Patch RTG DEMs dialog.

    (7) Fixed a bug such that DEMs in GeoTIFF format with a
        data type of unsigned integer did not import correctly.
 
    (8) Fixed a bug that affected creation of Data Summary
        tables (based on Horton-Strahler order) when the order
        of the pruned network exceeded 11.

    (9) Fixed a bug such that clicking on the Help button of the
        Extract > Finite Difference Grid dialogs caused RiverTools
        to lock up.

    (10) Fixed a bug in the Display > Masked Region dialog that
         prevented color from being set correctly with the "Use
         a single color" option.
 
    (11) Fixed a bug that caused the Display > Map Projection
         Info dialog to lock up on Macs when certain droplist
         combinations were attempted.
