<p style="margin-top:0;margin-bottom:0">my fitted vgm using Gaussian model ('Gau') via 'fit.variogram' in gstat looks as follows:</p>

<p style="margin-top:0;margin-bottom:0">Here are my questions:</p>
<p style="margin-top:0;margin-bottom:0"><br>
</p>
<p style="margin-top:0;margin-bottom:0">1)-is Gaussian model an optimal choice</p>
<p style="margin-top:0;margin-bottom:0">2)- my coordinates which I use for variogram fitting is in (lat, long), should I use UTM instead?</p>
<p style="margin-top:0;margin-bottom:0">3)- does the general variogram look visually correct , i.e., nugget, sill, and range values?</p>
