API for Different GeoRegion Properties ​

Retrieve the GeoRegion Shape ​

GeoRegions.coordinates Function
julia
coordinates(
    geo :: GeoRegion;
    n   :: Int = 1,
    derotate :: Bool = false,
    rotation :: Real = 0
) -> lon :: Vector{<:Real}, lat :: Vector{<:Real}

For a given GeoRegion, create longitude and latitude vectors of the shape.

Arguments

  • geo : A GeoRegion.

Keyword Arguments

  • n : The number of segments on each side of the shape.

  • derotate : If true, perform a "derotation" on the shape.

  • rotation : Angle (in degrees) of rotation for the final "derotated" shape about the GeoRegion centroid and projected into the X-Y cartesian coordinate system (in meters). A positive value relative to geo.θ will turn the final values about the centroid in the anti-clockwise direction. Default is 0.

Returns

  • lon : A vector of longitude points for the shape of the GeoRegion. If derotate = true, return instead the x-coordinates (in meters) about the centroid.

  • lat : A vector of latitude points for the shape of the GeoRegion. If derotate = true, return instead the y-coordinates (in meters) about the centroid.
