Description of the EEZ-View CD-ROM:
The EEZ-View CD-ROM contains GLORIA sidescan imagery of the deep-water portions (deeper than 200 meters) of the Exclusive Economic Zone. Its features include:
- ESRI ArcView Data Publisher-based viewer for the PC
- An interactive Windows help file providing a tour through each area
- User-friendly interface for ease of use by students
- Full ArcView interface for advanced users
- Tutorials on plate tectonics and remote sensing with GLORIA
- Highlights of interesting features from each of the geographic areas
- Interactive links to word definitions, enlarged images, captions
- Shaded-relief images and interpretive geologic maps, where available
- GLORIA images with 500-meter pixel resolution of the following areas:
|Gulf of Mexico
||Gulf of Alaska
More detailed imagery available soon:
Multiple CD-ROMs of high-resolution GLORIA imagery for all deep-water areas of the Pacific EEZ will become available during 1998. Features include:
- full-resolution mosaic of each 2° x 2° or 2° x 3° quadrangle (50-meter pixels)
- 5x desampled composite mosaic images with and without quad boundaries
- 10x desampled composite mosaic images with and without quad boundaries
- mosaic images in RAW format, enabling them to be viewed in any application that will open bitmaps of known image length and width
- information to allow the advanced GIS user to place the GLORIA mosaics in a digital map file
- ascii files of navigation and bathymetry data collected along ship trackline

Problems using your CD-ROM?
Please review the following information to help diagnose difficulties in running EEZ-View. The file "1_README.TXT" on the CD-ROM provides directions on how to start using EEZ-View.
The most basic system requirements to use the EEZ-View tutorial and software provided on the disc are as follows (performance will be extremely slow if memory and CD-ROM speed requirements are not met):
- IBM or compatible personal computer with 80386 or higher processor and a fast hard-drive system
- Microsoft Windows 3.xx, Windows NT 3.51 or NT 4.0 (not Windows 95)
- Video color palette must be 256 colors or greater
- 12-16 MB RAM for Windows 3.xx, 16-32 MB RAM for Windows NT
- 17 MB virtual memory
- CD-ROM drive, 4x or faster
- Setup requires approximately 700 KB of disc space for temporary files during installation
- True Type fonts must be enabled
- The installation dialog box always states the files you selected were loaded successfully. When you start EEZ-View, if dialog boxes appear asking for file locations, press the Cancel All button, quit EEZ-View and uninstall the software. You did not have enough space on your hard disk to install the data files. Either clear the required 300 MB and reinstall both the program and the data, or only install the EEZ-View program.
- Graphics within the EEZ-View Images window may become discolored during program use if other software programs are running simultaneously. Exit all programs and restart EEZ-View.
- The Fill Palette window appears when the EEZ-View Images window is restored from an icon. Close the Fill Palette window once and it should not appear again.
- The EEZ-View Text window may disappear or stop responding during program use. Click the program-reset button in the top left corner of the EEZ-View Images window.
- Versions of ArcView older than 2.1 will interfere with proper functioning of EEZ-View. See 1_README.TXT for installation instructions with an older ArcView in place.
- If you encounter other problems while using the EEZ-View software, simply exit all programs, and restart EEZ-View. If problems persist, reboot your computer.
How to order the CD:
The EEZ-View CD-ROM is officially published as USGS Open-File Report 97-540.
Paper atlases and CD-ROMs of GLORIA sidescan imagery are available in many university libraries and may be purchased through USGS Information Services in Denver, CO by calling 1-888-ASK-USGS.
