Formula

In the formulas that follow, the coordinate strings are symbolically represented as follows:

deg                     decimal degrees
adeg                   absolute value of decimal degrees
ideg                     integer degrees
sdeg                   signed integer degree
min                      real-number minutes
imin                      integer minutes
sec                      real-number seconds
lathem, lonhem    hemisphere abbreviation

In this conversion the parameter values remain unchanged but are re-ordered.

For the forward calculation from HDMS representation to DMSH representation, for each of latitude and longitude re-order the fields:
          from  	hem, ideg, imin, sec
          to       	ideg, imin, sec, hem

For the reverse calculation from DMSH representation to HDMS representation, for each of latitude and longitude re-order the fields:
          from  	ideg, imin, sec, hem 
          to       	hem, ideg, imin, sec

Example

Source CRS = WGS 84 (HDMS) (CRS code 63266412).
Latitude = N35°45’09.18", longitude =  W85°12’14.94"

Target CRS in DMSH = WGS 84 (CRS code 4326)
Latitude = 35°45’09.18"N, longitude =  85°12’14.94"W
