ArcGIS Map Document Readme

The map document and shapefiles used to create the trackline map 
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. The map document was 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 the map document, 14BIM05_location.mxd, and 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 up 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.
