GeoVu for Macintosh

Installing GeoVu Mac

GeoVu Mac requires 16MHz 68030 processor or later, 4 MB available RAM, 5.1 MB disk space, and System 7 or later. Larger data sets or long slide shows may require more disk space, RAM, and faster processors.

The current version of GeoVu Mac (6.11) will not work under MacOS 8. We are looking into this problem, and will post a new version of GeoVu when this is fixed. As a temporary workaround, you can use GeoVu version 6.0b3, which does run on Mac OS 8, and supports almost all of the features that 6.11 does. You can get version 6.0b3 from our ftp site. Download the file geovu6.0b3.sea.hqx from our site at: ftp://ftp.ngdc.noaa.gov/Access_Tools/GeoVu/Mac/old/geovu6.0b3.sea.hqx, and then proceed to step 2 below.

  1. Copy the file geovu_se.hqx to your hard drive from the /software/geovu/mac directory on the CD-ROM. Rename the file geovu_se.hqx to geovu.sea.hqx. The file name on the CD-ROM is truncated because the CD-ROM was made on a DOS-based PC.
  2. Decode geovu.sea.hqx with StuffIt Expander or BinHex. These are free software utilities available in many places on the Web including http://hyperarchive.lcs.mit.edu/HyperArchive.html. Then double-click the geovu.sea icon to install the geovu folder wherever you want on your hard drive. If you use StuffIt, this may happen automatically, depending on your settings. While installing GeoVu , note the location of the geovu directory. It will be necessary to manually copy files to this directory later in the installation process.

Viewing Data with GeoVu

  1. Copy all the files from the directory /software/geovu/mac/gv_misc (do not copy the gv_misc folder itself) on the CD-ROM to the GeoVu installation directory on your hard drive.
  2. To run GeoVu double-click the GeoVu icon from the GeoVu folder.
  3. Important: GeoVu Mac Bug:
    The first time a data set is accessed it may be necessary to repeat step 2a) and 2b) for GeoVu to navigate through the data correctly. If this is the case, repeat steps 2a) and 2b) for each data set (menu file) that you want to access from the CD-ROM. The GeoVu team is working to solve this problem and hopefully in the next release of GeoVu this will be solved. To download the latest version from our FTP site see our section below on Obtaining GeoVu Mac .
  4. Change (if necessary) the path shown in the text box with the title "CD-drive or data's drive" to the CD-ROM title (as shown on the desktop).
  5. Choose the file that you want to view; you may have to navigate (with double-clicks) through several menu levels. An Introduction screen is usually displayed first with some information about the data collection. If the data publisher has activated the automatic display function, the data file is displayed when you choose it. If not, you need to define a search.
  6. Select Create from the Search menu to display the dialog or window in which you can set search criteria. For image data, the Image Search Parameters dialog is displayed; for point data, the Plots: Title window appears.
  7. Set the criteria as you wish (specify geographic limits, display attributes, and so on), or click OK (image) or GO (point) to accept the defaults. The data are displayed in a new window.
  8. You can now examine the data in more detail with the tools on the right side of the window, or open more data windows.

The GeoVu executable is located in the GeoVu directory and is called "g2". See gvquick.* and gvhelp.* for details on using GeoVu.

Obtaining GeoVu Mac

GeoVu Mac is available on-line:ftp://ftp.ngdc.noaa.gov/Solid_Earth/Access_Tools/GeoVu/Mac/geovu.sea.hqx. The file "geovu.sea.hqx" is a self-extracting archive file.

You can also download these files via anonymous FTP from "ftp.ngdc.noaa.gov" in the "Access_Tools/GeoVu/Mac" directory. Below is an example of an FTP session run from the command line, but you may have easier-to-use Macintosh FTP software for this purpose. Be sure to download the file in ASCII mode.

FTP or World Wide Web

  1. When you download geovu.sea.hqx, decoding and installation of the geovu folder onto your hard disk may take place automatically depending on the setup of your FTP or Web software. If only the geovu.sea.hqx file is installed, decode it with StuffIt Expander or BinHex. These are free software utilities available in many places on the Web including http://hyperarchive.lcs.mit.edu/HyperArchive.html.
  2. After decoding, double-click the geovu.sea icon to install the geovu folder wherever you want on your hard drive.
