VECTOR FILES

Access to vector data files only on actual CD-ROM

There are two types of vector files available on the CD-ROM; an ASCII longitude, latitude, depth file and an ARC/INFO® interchange file. For each file type there are two datasets; a coastline file obtained from the NOS Medium Resolution Vector Shoreline for the Conterminous United States of America CD-ROM, and a 5 meter bathymetric contour file.

The UNIX formated michigan.e00 and coast.e00 files can be accessed by PC ARC/INFO® users by using the unix2dos command that is found in UNIX but also PC ARC/INFO® version 3.4.2 which contains this command.
