Map point

[francesco.spada(at)jrc.it (Francesco)]

Hi,

	I have produced a map in this way

latmin=39.74 & latmax=45.63
lonmin=-5.32 & lonmax=4.79

latcenter=42.8 & loncenter=-0.517

map_set,latcenter,loncenter,/lambert,/hires,
color=0,limit=[latmin,lonmin,latmax,lonmax]

map_continents,/countries

and now I want to have a point or a cross in the place of some
important spot like (42.938,-0.6)

How can I do it?

Also I have a 2d array with value of concentration that I want to plot
on the map and the array have the same (lat-lon) dimension of the map,
how can I do it?

Thanks

Ciao

Francesco
