GEODAS Coastlines 3/2/2007 The GEODAS Version 4.1/5.0 Coastlines are the same coastlines found on GEODAS 4.1 and 5.0 CD/DVDs, GEODAS Custom Data CDs and GEODAS On-line Downloads (when included). GEODAS Coastlines are binary files, and you must have the correct byter order for your computer. IBM-PC systems (MS Windows, Linux) will use LittleEndian. Macintosh and some UNIX systems (Sun, etc.) will use BigEndian. Users who do not have any GEODAS CD/DVD sets can download the coastlines and use GEODAS software (DVD version or Online Download version) to access the coastlines and export sections of coastlines to several formats. Simply unzip the coastline files and use GEODAS application Coastline Extractor to locate the coastline files.
