APPENDIX N: DESCRIPTION OF DATA TAPE FORMAT 



1. In order to facilitate use of the data described in this report, a 

 magnetic tape has been prepared which contains all the profile and hindcast 

 wave data. The tape does not include the tide data which were compiled from 

 paper tables. Copies of the tape can be arranged through the Information and 

 Analysis Center of CERC. Specific details of the tape and the format of the 

 9 data files are described in Table Nl .

WIS wave hindcast data 









* Counterclockwise from due east. 



Survey locality codes and Phase III hindcast grid codes are used to identify 

 the data from each locality. The shoreline angles are used in the 

 interpretation of the wave direction data. The specific details of the tape 

 format are: ASCII, 8 bit word size, 80 characters per record, 10 records per 

 block, 9 track, 1,600 bits per inch. This format should make it easily 

 readable on most computer systems. 



2. The survey data follow the BPAS "EDIT2" card image format (Fleming 

 and DeWall 1982). The data are in customary units (feet) with elevations 

 relative to NGVD. The information along with other useful parameters are 

 specified in a "Header Record," which is the first line on each survey data 

 file. The format of the Header Record is given in Table N2 . 



3. The data for each survey of a profile line are stored in a number 

 of 80 column lines which follow the header record. The format of the data is 

 given in Table N3 . The first line contains the date and the number of survey 

 points. The data within each file are sorted by profile number and then by 

 survey number (see Part 1, Table 1). If there are exactly four coordinate 

 pairs (only the first line is needed), then it is followed by a blank line.
