<p><font face="Consolas">Since your Landscan grid is at resolution 1
km, then the population count and density (per sq km) should be
the same.</font></p>
<p><font face="Consolas">Using the GRASS module r.out.xyz you can
get an ASCII text file with three columns: X,Y,value. The X-Y
are cell enters, and value would represent Population count.</font></p>
