latlong2km

longitude reference point (defaults to mean
  longitude)

lon0

latitude reference point (defaults to mean
  latitude)

lat0

Convert longitude and latitude co-ordinates to kilometres
  west-east and south-north from axes through
  (<code>lon0</code>,<code>lat0</code>) using the "spherical law of
  cosines".

This library implements density surface modelling of line
    transect data, based on the methods of Hedley et al. (2004). Some
    recent developments in the literature have also be incorporated.
    Outputs are point and interval estimates of population abundance
    and density.
