CLIWOC data base obtained from the web was modified for use in MICRODEM as follows:
- Created DEC_YEAR field.
- Removed records without LAT, LONG
- Create SHIP field, by concatenating the country and ID
fields.
- Fixed LONG to be -180 to 180
- Computed new file
- with speed and heading of the ship,
- at the center of the time interval
between two readings
- at the midpoint of the line connecting two
readings
- removed all speed over 25 knots (this is
generally over a day)
