worldrectgrid

grat = worldrectgrid(GI; width=(30,20), grid=nothing, annot_x=nothing)

or

grat = worldrectgrid(; proj="projection", width=(30,20), grid=nothing, annot_x=nothing)

Create a grid of lines (graticules) in projected coordinates. The projection system is extracted from the GI metadata.

GI: A GMTgrid or GMTimage data type created with the worldrectangular function.
proj: Pass a proj4 string or Symbol describing the projection. Alternatively pass a referenced GMTdataset from which the projection will be extracted.
width: A scalar or two elements array/tuple with increments in longitude and latitude. If scalar, width_x = width_y.
grid: Instead of using the width 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 when grat is used in the [plotgrid!] function, but depending on the projection and the latlim 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.
