Classify azimuth of line segments

Description

Classify azimuth of line segments

Usage

classifyAz(sl)

Arguments

sl	A SpatialLines* object

Value

A numeric vector with the segment azimuth values (in decimal degrees)

Examples

build_seg = toSeg(build[1, ])
az = classifyAz(build_seg)
plot(build_seg, col = rainbow(4)[cut(az, c(0, 90, 180, 270, 360))])
raster::text(
  # rgeos::gCentroid(build_seg, byid = TRUE),
  as(sf::st_centroid(sf::st_geometry(sf::st_as_sf(build_seg))), "Spatial"),
  round(az)
)
