Hi, earlier, I used those functions to transform a lat-long database to a Lambert Azimuthal Equal Area (LAEA) :

Lam_proj <- project(cbind(Grille$x, Grille$y),"+proj=laea +lat_0=latitudem_grid +lon_0=longitudem_grid +x_0=0 +y_0=0 +a=6370997 +b=6370997 
+units=m")


Now that my calculations is done, I'd like to show the result and I'd need to re-transform the LAEA database to a lat-long database (since "surfm" in Matlab needs lat-long).

I used : project(cbind(Prev$x, Prev$y),"+proj=latlong")

But I got this error message : "latitude or longitude exceeded limits"

Thanks for any help!
