geocode2lat(geocode)
geocode2lon(geocode)
The geocode2lat
and geocode2lon
functions decode a
geocode into a latitude or longitude coordinate, respectively. The
returned coordinate is in the decimal degrees format. In
version 5.01.1193955804 20071101 and later, an invalid geocode value
(e.g. -1) will return NaN (Not a Number).
If you want DDDMMSS "degrees minutes seconds" (DMS) format, you
can use dec2dms
to convert it.
EXAMPLEselect city, geocode2lat(geocode), geocode2lon(geocode) from geotest;
CAVEATS
As with latlon2geocode
, the geocode
value is platform-dependent
in accuracy and format, so it should not be copied across platforms,
and the returned coordinates from geocode2lat
and
geocode2lon
may differ up to about half a minute from the
original coordinates (due to the finite resolution of a long
).
In version 5.01.1193955804 20071101 and later, an invalid geocode value
(e.g. -1) will return NaN
(Not a Number).
