The goal of ozmaps is to get maps of Australia to plot!
Install from CRAN with
install.packages("ozmaps")The development version of ozmaps may be installed directly from github.
devtools::install_github("mdsumner/ozmaps")The package includes some simple features data, which can be
used independently of ozmaps with the sf package. If
required, install sf from CRAN.
NOTE: Since April 2020) we must have sf installed because of requirements of the tibble package.
If sf causes you problems or you can’t work with it get in touch and I will help you.
install.packages("sf")Plot Australia with states.
library(ozmaps)
ozmap()
Plot Australia without states.
ozmap(x = "country")
Add to an existing plot.
plot(quakes[c("long", "lat")], xlim = c(120, 190))
ozmap(add = TRUE)
Obtain the data used in sf form.
sf_oz <- ozmap_data("states")
tibble::as_tibble(sf_oz)

library(sf)
if (utils::packageVersion("paletteer") < '1.0.0') {
pal <- paletteer::paletteer_d(package = "ochRe", palette = "namatjira_qual")
} else {
pal <- paletteer::paletteer_d(palette = "ochRe::namatjira_qual")
}
opal <- colorRampPalette(pal)
nmjr <- opal(nrow(sf_oz))
plot(st_geometry(sf_oz), col = nmjr)
## plot directly with ggplot2
library(ggplot2)
ggplot(sf_oz, aes(fill = NAME)) + geom_sf() + coord_sf(crs = "+proj=lcc +lon_0=135 +lat_0=-30 +lat_1=-10 +lat_2=-45 +datum=WGS84") + scale_fill_manual(values = nmjr)
Plot the ABS layers (from 2016).
ozmap("abs_ced", col = opal(nrow(abs_ced)))
ozmap("abs_ste", col = opal(nrow(abs_ste)))
These ABS layers abs_ced, abs_lga, and
abs_ste are derived from the 2016 sources and simplified
using
rmapshaper::ms_simplify(, keep = 0.05, keep_shapes = TRUE)
so all the original polygons are there. There is sufficient detail to
map many (most?) of the regions on their own, which was a major goal for
this package.
The cache of the source data at original resolution is available in ozmaps.data.
Compare the detail of Bruny Island here in this box, compared with the very basic maps package layer.
library(dplyr)
kbor <- abs_lga %>% dplyr::filter(grepl("Kingborough", NAME))
bb <- st_bbox(kbor)
layout(matrix(c(1, 1, 1, 2, 2, 2, 2, 2, 2), nrow = 3))
plot(kbor, reset = FALSE, main = "Kingborough (TAS)")
rect(bb["xmin"], bb["ymin"], bb["xmax"], bb["ymax"])
library(mapdata)
#> Loading required package: maps
par(mar = rep(0, 4))
plot(c(145, 148.5), c(-43.6, -40.8), type = "n", asp = 1/cos(mean(bb[c(2, 4)]) * pi/180), axes = FALSE, xlab = "", ylab = "")
maps::map(database = "worldHires", regions = "australia", xlim = c(145, 148.5), ylim = c(-43.6, -40.8), add = TRUE)
rect(bb["xmin"], bb["ymin"], bb["xmax"], bb["ymax"])
