Multibeam Mapping of Selected Areas of the Outer Continental Shelf, Northwestern Gulf of Mexico--Data, Images, and GIS

This Open-File Report contains an ArcExplorer 2.0 Project containing TIFF images of multibeam bathymetry and acoustic backscatter data from the 1997 and 2002 surveys of selected areas of the outer continental shelf, Northwestern Gulf of Mexico

ArcExplorer is a freeware, GIS software package developed by ESRI. This project allows the user to overlay, zoom, pan, and query the Northwestern Gulf of Mexico multibeam and other data. Other spatial data in UTM coordinates can be added to this project.

This ArcExplorer project will only run an a PC running Windows 98/2000/NT.

If the user already has ArcExplorer 2.0 installed on the computer follow the instructions below.

If the user needs to install ArcExplorer 2.0, download the software directly from ESRI.

1. Download the wgomproj.tgz file (105Mb compressed, 264Mb uncompressed).

2. Wgomproj.tgz is a bundled and compressed folder containing all the files needed for the ArcExplorer project. Wgomproj.tgz needs to be uncompressed and unbundled using WinZip or a similar program before opening the project in ArcExplorer.

3. Double click on the wgomproj.tgz file and WinZip will uncompress the file resulting in a new file called wgomproj.tar.

4. Double click on the wgomproj.tar file and WinZip will unbundle the file into a directory called wgomproj.

5. Double click on the wgom.aep file within the wgomproj folder to start the ArcView project

Disclaimer: Downloading files from the Internet can sometimes be problematic. Different web browsers and operating systems act differently. The instructions above may vary from system to system or may not work at all.

One known problem is sometimes Netscape Navigator automatically changes the .tgz suffix to .tar during the download. If this happens change the .tar suffix back to .tgz after the download. Double click on the wgomproj.tgz icon and Winzip should start up.
