GIS:
Two Environmental System Research Institute (ESRI) ArcView 3.3       Geographic Information System (GIS) project files reside in the top-level       directory of this DVD. The project file       allpulley.apr does not require any extensions       that are not standard to ArcView3X. The project file       allpulley_sa.apr contains grids requiring the       Spatial Analyst Extension. All associated GIS files are       contained in subdirectories under the data directory. The user must have a       copy of ESRI ArcView 3.2 or later in order to view the project files.       Visit the ESRI Web site (http://www.esri.com/) for information concerning this       and other software.

These project files (allpulley.apr and       allupulley_sa.apr) require the directory       structure used on this DVD-ROM, and contain a startup script which prompts       the user for the drive letter of the DVD-ROM drive. This information is       needed in order to establish "hotlinks" found within the project files. If       the ArcView project file and the data directory are copied to the hard       disk (maintaining the original directory hierarchy), then the location       entered for the startup script should refer to the directory location of       the ArcView project file. If for some reason the directory location is       entered incorrectly, then the user can click on the pink button with the       yellow CD () to reenter the information.

For those users who do not have ArcView 3.2 or later, the individual       GIS data files can still be viewed with a compatible       GIS viewer, or a free GIS viewer such as       ArcExplorer. This GIS data viewer is available from ESRI (http://www.esri.com/).       Please note that the ArcExplorer software is limited to the Microsoft       Windows operating systems and some UNIX operating systems.

Extensions:The project files are setup to       "hotlink" to the JPEG bottom photographs and seismic-reflection profiles.       The JPEG (JFIF) Image Support extension must be loaded for this to work.       This extension will be loaded by default within the project file. 

The allpulley_sa.apr utilizes gridded data       sets. As such, the Spatial Analyst extension must be loaded in order to       view and manipulate these grids. This extension is loaded by default       within the allpulley_sa.apr. For users who do       not have the Spatial Analyst extension,       allpulley.apr utilizes TIFF images of the grid       data sets. The necessary extensions will be loaded by default within the       project file.

Projection:All of the shapefiles are in the       Geographic NAD83 coordinate system. The project file       (allpulley.apr) contains images of the       bathymetry data, and these TIFF images are in the UTM, Zone       17, NAD 83 projection, with those views projected       accordingly. The grid data sets that appear in       allpulley_sa.apr are in the UTM,       Zone 17, NAD 83 projection, with those views projected       accordingly.

Hotlinking:Each point within the point shapefile       indicating image locations presented within the project file is       "hotlinked" to a JPEG image of a bottom photograph from that location.       Similarly, each seismic-reflection trackline is "hotlinked" to a JPEG       image of the corresponding seismic-reflection profile. To view these       images, make the appropriate theme the active theme. This should activate       the hotlink tool () within the project tool bar. Click on this button and       then on an individual record within the theme. The corresponding JPEG       image will be opened in a separate view window so the user can pan and       zoom on the image.
