ArcGIS Project Read-Me

The map documents and shapefiles used to create the trackline maps on 
this disc 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 
documents were created uisng Environmental Systems Research Institute 
(ESRI) ArcView 3.3 and ArcGIS 8.3 and 10 GIS software.  The shapefiles 
provided may also be viewed using other versions of ArcView, ArcGIS, or 
public-domain software ArcExplorer 
(http://www.esri.com/software/arcexplorer/index.html) or GeoMapApp 
(http://www.geomapapp.org), which are compatible with all platforms.
	
The map documents are named all.mxd, area_a.mxd, and area_b.mxd.  These 
maps show trackline navigation in the survey area.  Inset maps also show 
start of lines and 500-shot-interval locations along each line.

The list below describes the shapefiles provided with the ArcGIS project. 
Metadata are available as HTML documents (viewable with any Web browser) 
and XML documents (used by ArcCatalog).
