[R-sig-Geo] gstat - variogram fit analysis question

[Joelle k. Akram]

hello,


my fitted vgm using Gaussian model ('Gau') via 'fit.variogram' in gstat looks as follows:

[cid:c41e92ec-56ae-42df-8131-1e2d960e0ce3]


Here are my questions:


1)-is Gaussian model an optimal choice

2)- my coordinates which I use for variogram fitting is in (lat, long), should I use UTM instead?

3)- does the general variogram look visually correct , i.e., nugget, sill, and range values?


thanks,

Joe
