graticules
grat = graticules(D, width=(30,20), grid=nothing, annot_x=nothing)
or
grat = graticules(; proj="projection", width=(30,20), pm=0, grid=nothing, annot_x=nothing)
Create a projected graticule GMTdataset with meridians and parallels at width
intervals.
D
: A GMTdataset (or vector of them) holding the projection info. Instead of GMTdataset type, this argument may also be a referenced grid or image type.proj
: Alternatively pass a proj4 string or Symbol describing the projectionpm
: The projection prime meridian (Default is 0 or whatever is in D.proj4).width
: A scalar or two elements array/tuple with increments in longitude and latitude. If scalar, widthx = widthy.grid
: Instead of using thewidth
argument, that generates an automatic set of graticules, one may pass a two elements Vector{Vector{Real}} with the meridians (grid[1]) and parallels (grid[2]) to create.annot_x
: By default, all meridians are annotated whengrat
is used in the plotgrid! function, but depending on the projection and thelatlim
argument used in worldrectangular we may have the longitude labels overlap close to the prime meridian. To minimize that pass a vector of longitudes to be annotated. e.g.annot_x=[-180,-150,0,150,180]
will annotate only those longitudes.
Returns
A Vector of GMTdataset containing the projected meridians and parallels. grat[i]
attributes store information about that element lon,lat.
Example
using GMT
grat = graticules(proj="+proj=ob_tran +o_proj=moll +o_lon_p=40 +o_lat_p=50 +lon_0=60");
