deg_grid_polar | R Documentation |
Outputs a list of grid lines that can be used to plot a grid on polar stereographic maps. Requires a spatial object projected using UTM coordinates
deg_grid_polar(
dat,
lat.interval = 10,
lon.interval = 45,
n.points = 1000,
proj4.utm = TRUE,
proj4.deg = "+proj=longlat +datum=WGS84"
)
dat |
Spatial object projected using UTM coordinates, such as |
lat.interval |
the interval of latitude grids for polar stereographic maps ( |
lon.interval |
the interval of longitude grids for polar stereographic maps ( |
n.points |
number of points used in creating the grid lines. The more points, the smoother the lines. |
proj4.utm |
projection in |
proj4.deg |
desired decimal degree projection. Uses a reasonable default projection. Do not change. |
round.map |
logical indicating whether the desired map is round |
Returns a UTM coodrinate grid.
