Functions that convert statistical rectangle codes under:
1) a traditional Icelandic system ('tilkynningaskyldurreitakerfid')
(see d2r
and d2sr
) and
2) set up in systems based on minutes and degrees
(see d2mr
and d2dr
)
to decimal representation of rectangles center positions
in degreees latitude and longitude.

r2d
with a resolution of 30 min latitue and 1 deg
longitude (the Icelandic numbering system, 'tilkynningaskyldureitir').
sr2d
with a resolution of 15 min latitude by 30 min
longitude in the Icelandic numbering system for statistical rectangles
which starts counting at 60 deg N latitude, with sub-rectangles of 30
min lat by 1 deg lon coded 1, 2, 3 and 4 for the NW, NA, SW and SA
quadrants respectively,
mr2d
with resolution given in dlat
by
dlon
minutes lat and lon,
dr2d
for rectangles with resolution given in dlat
by
dlon
degrees lat and lon, code system starting at latitude startLat
.
dataframe of center positions (latitude lat
and longitude
lon
) of rectangles in one of the coding systems
Mostly used for plotting.

), STJ (for mr, dr
).
