In MikkoVihtakari/PlotSvalbard: PlotSvalbard - Plot research data from Svalbard on maps

Decimal degree grid from UTM projected spatial objects

Description

Outputs a list of grid lines that can be used to plot a grid on maps. Requires a spatial object projected using UTM coordinates

Usage

deg_grid(
  dat,
  round.lat = FALSE,
  n.lat.grid = 3,
  round.lon = FALSE,
  n.lon.grid = 3,
  n.points = 30
)

Arguments

dat	basemapLimits object
round.lat	specifying the level of rounding to be used to plot latitude grid lines. Overrides n.lat.grid
n.lat.grid	number of latitude grid lines. Alternatively use round.lat
round.lon	specifying the level of rounding to be used to plot longitude grid lines. Overrides n.lon.grid
n.lon.grid	number of longitude grid lines. Alternatively use round.lon
n.points	number of points used in creating the grid lines. The more points, the smoother the lines.

Details

This is an internal function, which is automatically run by the basemap function. Common users do not need to worry about these details.

Value

Returns a UTM coodrinate grid.
