Hi Dash,
   Yup here's the function cal and the function:

if (projectLatLon($lat,$lon))
{
...do stuff
}
else
{
  ..do other stuff
}

function projectLatLon($lat,$lon)
{
GLOBAL $lccXY;
$dlat = doubleval($lat);
$dlon = doubleval($lon);

//project from geodetic coordinate degrees
$parms1[0] = "proj=longlat";
$parms1[1] = "ellps=GRS80";
$parms1[2] = "datum=NAD83";
$parms1[3] = "no_defs";
$projLonLat = pj_init($parms1);

//project to lambert conical x,y
$parms2[0] = "proj=lcc";
$parms2[1] = "ellps=GRS80";
$parms2[2] = "datum=NAD83";
$parms2[3] = "lat_0= 49.0";
$parms2[4] = "lon_0= -95.0";
$parms2[5] = "lat_1= 49.0";
$parms2[6] = "lat_2= 77.0";
$parms2[7] = "units=m";
$projLCC = pj_init($parms2);
$lccXY = pj_transform($projLonLat, $projLCC, $dlon, $dlat,0 );
if ($lccXY == 0)
{
  pj_free($pj);
  return FALSE;
}
else
{
pj_free($pj);
return TRUE;
}

}

thx,
Paul
