So it is calcalated automatically? Could I, say to have a survey with year 2000 declination value and centerlines in it will be adjusted to respective dates?
Yes. You can specify declination for 1990 and 2000 (e.g. -declination [1990 2.0 2000 3.0 deg]), and all centerlines between will be adjusted (e.g. in 1995, declination 2.5deg will be used).
You may generate the declination for one datum or for time interval on page: http://www.ngdc.noaa.gov/seg/geomag/jsp/struts/calcDeclination/ and copy/paste it to your .th file. MS. --
