libgeo-coordinates-osgb-perl binary package in Ubuntu Trusty i386

 Geo::Coordinates::OSGB and Geo::Coordinates::OSTN02 offer an implementation
 of co-ordinate conversion for England, Wales, and Scotland based on formulae
 published by the Ordnance Survey of Great Britain.
 .
 These modules will convert accurately between an OSGB national grid
 reference and lat/lon coordinates based on the OSGB geoid model.
 .
 To get more accurate results you need to combine this module with its
 companion Geo::Coordinates::OSTN02 which implements the transformation that
 now defines the relationship between GPS survey data based on WGS84 and the
 British National Grid.
