This is correct for the either case (without the extra "+"):
"+proj=longlat +ellps=WGS84 +datum=WGS84 +no_defs"
There is some limited supported for the 0, 360 convention in PROJ.4 with the
+over argument:
"+proj=longlat +ellps=WGS84 +datum=WGS84 +over +no_defs"
but, that will not perform the req
Jonathan,
I do not think so, but I think you can do something like:
crd <- coordinates(x)
crd[crd[,1] > 180, 1] <- crd[crd[,1] > 180, 1] - 360
sp <- SpatialPoints(crd)

Folks:
I have two sets of spatialpoints data, one that is in lat long which
longitude ranging from -180 to 180, and another that ranges from 0 to 360.
What are the appropriate proj settings for these two different datasets
such that one can be properly reprojected to the other? I have:
"++proj=
