#+TITLE: utm-ups
This is a Common Lisp library to convert coordinates between Latitude/Longitude
and UTM (Universal Transverse Mercator) or UPS (Universal Polar Stereographic).
* API
In the library, latitude and longitude are represented by real numbers
(degrees), positive for northern latitude and eastern longitudes, and negative
for southern latitude and western longitudes.
UTM zones are represented by positive integers for northern latitudes and
negative integers for southern latitudes.
UPS zones are either ~t~ for northen latitudes or ~nil~ for southern latitudes.
** Ellipsoids
#+BEGIN_SRC lisp
*ellipsoid*
#+END_SRC
Special variable containing the name of the ellipsoid that will be used in
computations ("WGS 84" by default).
#+BEGIN_SRC lisp
(ellipsoids) -> list
#+END_SRC
Return the list of supported ellipsoids.
** Main functions
#+BEGIN_SRC lisp
(lat/lon->utm-ups latitude longitude &optional zone) -> list, string
#+END_SRC
Return the UTM or UPS zone, easting and northing for the given /latitude/ and
/longitude/. The second returned value is the UTM or UPS band. The /zone/
parameter can be used to force in which UTM zone the coordinates will be
computed.
#+BEGIN_SRC lisp
(utm/ups->lat/lon zone easting northing) -> list
#+END_SRC
Return the latitude and longitude for the given UTM or UPS /zone/, /easting/
and /northing/.
#+BEGIN_SRC lisp
(band latitude longitude) -> string
#+END_SRC
Return the UTM or UPS band for the given /latitude/ and /longitude/.
#+BEGIN_SRC lisp
(format-utm/ups zone easting northing &optional band) -> string
#+END_SRC
Return UTM or UPS coordinates as a string. If /band/ is not specified, it will
be set to ~+~ for northern zones and to ~-~ for southern zones.
#+BEGIN_SRC lisp
(format-lat/lon latitude longtude &optional decimal) -> string
#+END_SRC
Return the coordinates as a string. If /decimal/ is not ~nil~, decimal notation
will be used for angles, otherwise d°m's" notation will be used.
** UTM specific functions
#+BEGIN_SRC lisp
(lat/lon->utm latitude longitude &optional zone) -> list, string
#+END_SRC
Return the UTM zone, easting and northing for the given /latitude/ and
/longitude/. The second returned value is the UTM band. The /zone/ parameter
can be used to force in which UTM zone the coordinates will be computed.
#+BEGIN_SRC lisp
(utm->lat/lon zone easting northing) -> list
#+END_SRC
Return the latitude and longitude for the given UTM /zone/, /easting/ and
/northing/.
#+BEGIN_SRC lisp
(utm-zone latitude longitude) -> integer
#+END_SRC
Return the UTM zone number for the given /latitude/ and /longitude/.
#+BEGIN_SRC lisp
(utm-band latitude) -> string
#+END_SRC
Return the UTM band for the given /latitude/.
** UPS specific functions
#+BEGIN_SRC lisp
(lat/lon->ups latitude longitude) -> list, string
#+END_SRC
Return the UPS hemisphere, easting and northing for the given /latitude/ and
/longitude/. The second returned value is the UPS band.
#+BEGIN_SRC lisp
(ups->lat/lon northp easting northing) -> list
#+END_SRC
Return the latitude and longitude for the given UPS hemisphere (/northp/),
/easting/ and /northing/.
#+BEGIN_SRC lisp
(ups-band latitude longitude) -> string
#+END_SRC
Return the UPS band for the given /latitude/ and /longitude/.

"30T 0440627 4476090"
#+END_SRC
Get back the latitude and longitude of Madrid:
#+BEGIN_SRC lisp

"40°25'59.9\"N 3°42'00.0\"W"
#+END_SRC
Get the coordinates of the McMurdo station either in UTM or in UPS:
#+BEGIN_SRC lisp

(-58 539204.7698733974d0 1358215.357267417d0)

(NIL 2312265.8557648384d0 682275.9727717754d0)
"B"
#+END_SRC
Get back the latitude and longitude of the McMurdo station:
#+BEGIN_SRC lisp
> (utm-ups:utm/ups->lat/lon -58 539204.7698733974d0 1358215.357267417d0)
