ArcGIS Map Document Readme

The map documents and shapefiles used to create the trackline maps 
in this archive can be found in the arc.zip file located in the 
arc subfolder of the software folder located at the top level of the 
disc’s file listings. The map documents were created with PC-compatible 
Environmental Systems Research Institute (Esri) ArcGIS 10.2 software. The 
arc.zip file also contains an images folder, which stores .gif images of 
each trackline's subbottom profile.  

To access these images using ArcMap 10.2, open a map document, then click 
on the hyperlink button (the symbol is a lightning bolt) located on the 
toolbar. Once this button is activated, the tracklines will all change 
to blue, indicating they have hyperlinks. Selecting a trackline will open 
the associated printable profile image. Shapefiles may also be viewed 
using other versions of Esri ArcGIS for Desktop software including their 
free software, ArcGIS Explorer 
(http://www.esri.com/software/arcgis/explorer/index.html); however, the 
hyperlink feature is disabled when using this software. 
	
The map document displays trackline navigation, the start-of-line (green 
dots), and 1,000-shot-interval locations (black dots) along each line. 
The Points to Lines ArcScript, downloadable at 
http://arcscripts.esri.com/details.asp?dbid=12702, was used to create the 
trackline layer. 

The list below describes the shapefiles provided with the ArcGIS map 
document. Metadata are available as FGDC-compliant text and 
Extensible Markup Language (XML) documents (used by ArcCatalog).

*Note: ArcMap 10.2 .mxd files are not backward compatible; however, the 
shapefiles can be viewed using earlier versions of ArcGIS software.
