st_normalize transforms the coordinates in the input feature to fall between 0 and 1. By default the current domain is set to the bounding box of the input, but other domains can be used as well

st_normalize(x, domain = st_bbox(x), ...)

Arguments

x

object of class sf, sfc or sfg

domain

The domain x should be normalized from as a length 4 vector of the form c(xmin, ymin, xmax, ymax). Defaults to the bounding box of x

...

ignored

Examples

p1 = st_point(c(7,52)) st_normalize(p1, domain = c(0, 0, 10, 100))
#> POINT (0.7 0.52)
p2 = st_point(c(-30,20)) sfc = st_sfc(p1, p2, crs = 4326) sfc
#> Geometry set for 2 features #> geometry type: POINT #> dimension: XY #> bbox: xmin: -30 ymin: 20 xmax: 7 ymax: 52 #> epsg (SRID): 4326 #> proj4string: +proj=longlat +datum=WGS84 +no_defs
#> POINT (7 52)
#> POINT (-30 20)
sfc_norm <- st_normalize(sfc) st_bbox(sfc_norm)
#> xmin ymin xmax ymax #> 0 0 1 1
