Visualization:
The spatial relationship between the high-resolution bathymetry and       bottom photographs is difficult to visualize in a standard GIS. One way       this is done is to "hotlink" the bottom photographs to the navigation       points marking the location. This method works fine for looking at       individual photos, but is difficult to use when attempting to understand       the relationship between several photos, or several photos and the       bathymetry. For this reason, a subset of the bottom photographs was       selected to be combined with the bathymetry as vertical images in       Fledermaus. Fledermaus is a 3D visualization software package developed by       Interactive Visualization       Systems (IVS)       and has the capabilities to create MPEG animations. Figures 7, 8 and 9 are snapshot examples of the bottom photographs as       vertical images with the underlying bathymetry in Fledermaus. 

The vertical exaggeration for the bathymetry is 18X, and the bottom       photographs are also exaggerated. Although each photo has an actual       footprint of approximately 1 m, for the purposes of this visualization,       each vertical photograph represents 200 m in width and 180 m in height.       This extreme exaggeration is necessary so that features within each image       can be viewed easily. The blue diamonds in each figure represent the       locations of bottom photographs, while the red squares indicate photograph       locations that are used as vertical images. 

 These images are thumbnails of Figures 7, 8 and 9 - left to right. Figure 7 (left image) represents the southern portion of       the study area, while figures 8 and 9 represent the central and northern portions       respectively. These figures represent snapshots from MPEG animations that       are available on the DVD. Clicking on one of the images will open a       snippet of the MPEG animation associated with that portion of the study       area. 

The animations were created using IVS software. The initial       flight path was generated with a 3D mouse (bat) "flying" through a       Fledermaus scene. The flight path was then smoothed and the MPEG animation       from each area was created using the Movieclient program within the IVS software package.       These files are MPEG-1 format which should be viewable on most computer       systems. The software package VideoMach was used to extract the small       snippets of animation presented here. 

The scenes used to create the animations are also available on this DVD       from the data/visualization directory. These files are only       available within the WinZip files.IVS has a free viewer,       iView3D (http://www.ivs3d.com/products/iview3d/), which is       available to view files in the Fledermaus file format.
