Statement

XY coordinates extracted from em300 data files for centre beam position. Decimated so that only every 10th position used to reduce file sizes. Extraction of data scripted on Tesla processing workstation:

1. Run unix script nav2arcinfo *.em3000.nav

2. At Arc prompt run &r load_lines

This process produces a line coverage of the centrebeam positions with segments atributed with line number and Cruise ID.
