In wfmackey/absmapsdata: A catalogue of ready-to-use ASGS (and other) sf objects
:warning: This package is not owned, run, or endorsed by the ABS.
Data contained in this package are compressed, re-projected, renamed
and stored as sf objects to be useful for making maps in R. If
conducting spatial analysis, or any analysis that requires precise
area boundaries, please use the original shapefiles provided by the
ABS and others.
absmapsdata
absmapsdata is a user-generated package to make it easier for R users
to access ABS (and other) spatial structure names/codes and produce maps
using this data. The package contains compressed (lossy), tidied, and
lazily-loadable sf objects that hold geometric information about data
structures in Australia. It also contains a correspondences files
provided by the ABS.
:white_check_mark: It is now recommended that you use
strayr::read_absmap to
access data stored in absmapsdata. To download and read these data
files without installing the whole absmapsdata package, please use
strayr::read_absmap, for example:

Installation
You probably don’t need to install the full absmapsdata package (see
above).
But if you want to, you can install absmapsdata from Github. The
package contains a lot of data, so installing using
remotes::install_github may fail if the download times out. If this
happens, set the timeout option to a large value and try again,
i.e. run:
options(timeout = 1000)
remotes::install_github("wfmackey/absmapsdata")
The sf package is required to handle the sf objects:
library(sf)
Data loaded with this package
Available maps are listed below. These will be added to over time. If
you would like to request a map to be added, let me know via an issue on
this Github repo.

Correspondences
This package also contains a number of 2016 population-weighted ABS
correspondences (the most recent) that can be found on the data.gov.au
website.
:white_check_mark: Use
strayr::read_correspondence_tbl
to access correspondence this data, rather than loading the whole
absmapsdata package, e.g.:

The resulting sf object contains one observation per area (in the
following examples, one observation per sa3). It stores the geometry
information in the geometry variable, which is a nested list
describing the area’s polygon. The object can be joined to a standard
data.frame or tibble and can be used with dplyr functions.
Creating maps with your sf object
We do all this so we can create gorgeous maps. And with the sf object
in hand, plotting a map via ggplot and geom_sf is simple.
map <-
sa32016 %>%
filter(gcc_name_2016 == "Greater Melbourne") %>% # let's just look Melbourne
ggplot() +
geom_sf(aes(geometry = geometry)) # use the geometry variable
map
The data also include centroids of each area, and we can add these
points to the map with the cent_lat and cent_long variables using
geom_point.
map <- sa32016 %>%
filter(gcc_name_2016 == "Greater Melbourne") %>% # let's just look Melbourne
ggplot() +
geom_sf(aes(geometry = geometry)) + # use the geometry variable
geom_point(aes(cent_long, cent_lat)) # use the centroid long (x) and lats (y)
map
Cool. But this all looks a bit ugly. We can pretty it up using ggplot
tweaks. See the comments on each line for its objective. Also note that
we’re filling the areas by their areasqkm size, another variable
included in the sf object (we’ll replace this with more interesting
data in the next section).
map <- sa32016 %>%
filter(gcc_name_2016 == "Greater Melbourne") %>% # let's just look Melbourne
ggplot() +
geom_sf(aes(geometry = geometry, # use the geometry variable
fill = areasqkm_2016), # fill by area size
lwd = 0, # remove borders
show.legend = FALSE) + # remove legend
geom_point(aes(cent_long,
cent_lat), # use the centroid long (x) and lats (y)
colour = "white") + # make the points white
theme_void() + # clears other plot elements
coord_sf()
map
Joining with other datasets
At some point, we’ll want to join our spatial data with
data-of-interest. The variables in our mapping data—stating the numeric
code and name of each area and parent area—will make this relatively
easy.
For example: suppose we had a simple dataset of median income by SA3
over time.
# Read data in some data
income <- read_csv("https://raw.githubusercontent.com/wfmackey/absmapsdata/master/img/data/median_income_sa3.csv")

#> 4 Goulburn - Mulwaree 2010-11 38269
#> 5 Young - Yass 2010-11 39489
#> 6 Gosford 2010-11 38189
This income data contains a variable sa3_name_2016, and we can use
dplyr::left_join() to combine with our mapping data.
combined_data <- left_join(income,
sa32016,
by = "sa3_name_2016")
Now that we have a tidy dataset with 1) the income data we want to plot,
and 2) the geometry of the areas, we can plot income by area:
map <- combined_data %>%
filter(gcc_name_2016 == "Greater Melbourne") %>% # let's just look Melbourne
ggplot() +
geom_sf(aes(geometry = geometry, # use the geometry variable
fill = median_income), # fill by unemployment rate
lwd = 0) + # remove borders
theme_void() + # clears other plot elements
labs(fill = "Median income")

Why does this package exist?
The motivation for this package is that maps are cool and fun and are,
sometimes, the best way to communicate data. And making maps is R with
ggplot is relatively easy when you have the right object.
Getting the right object is not technically difficult, but requires
research into the best-thing-to-do at each of the following steps:
- Find the ASGS ABS spatial-data page and determine the right file to
download.
- Read the shapefile into
R using one-of-many import tools.
- Convert the object into something usable.
- Clean up any inconsistencies and apply consistent variable
naming/values across areas and years.
- Find an appropriate compression function and level to optimise output.
For me at least, finding the correct information and developing the best
set of steps was a little bit interesting but mostly tedious and
annoying. The absmapsdata package holds this data for you, so you can
spend more time making maps, and less time on Stack Overflow, the ABS
website, and lovely-people’s wonderful
blogs.
Comments/complaints/requests
The best avenue is via a Github issue at
wfmackey/absmapsdata/issues.
This is also the best place to request data that isn’t yet available in
the package.

We want your feedback!
Note that we can't provide technical support on individual packages. You should contact the package authors for that.
:warning: This package is not owned, run, or endorsed by the ABS. Data contained in this package are compressed, re-projected, renamed and stored as
sfobjects to be useful for making maps in R. If conducting spatial analysis, or any analysis that requires precise area boundaries, please use the original shapefiles provided by the ABS and others.
absmapsdata
absmapsdata is a user-generated package to make it easier for R users
to access ABS (and other) spatial structure names/codes and produce maps
using this data. The package contains compressed (lossy), tidied, and
lazily-loadable sf objects that hold geometric information about data
structures in Australia. It also contains a correspondences files
provided by the ABS.
:white_check_mark: It is now recommended that you use
strayr::read_absmapto access data stored inabsmapsdata. To download and read these data files without installing the wholeabsmapsdatapackage, please usestrayr::read_absmap, for example:

Installation
You probably don’t need to install the full absmapsdata package (see
above).
But if you want to, you can install absmapsdata from Github. The
package contains a lot of data, so installing using
remotes::install_github may fail if the download times out. If this
happens, set the timeout option to a large value and try again,
i.e. run:
options(timeout = 1000)
remotes::install_github("wfmackey/absmapsdata")
The sf package is required to handle the sf objects:
library(sf)
Data loaded with this package
Available maps are listed below. These will be added to over time. If you would like to request a map to be added, let me know via an issue on this Github repo.

The resulting sf object contains one observation per area (in the
following examples, one observation per sa3). It stores the geometry
information in the geometry variable, which is a nested list
describing the area’s polygon. The object can be joined to a standard
data.frame or tibble and can be used with dplyr functions.
Creating maps with your sf object
We do all this so we can create gorgeous maps. And with the sf object
in hand, plotting a map via ggplot and geom_sf is simple.
map <-
sa32016 %>%
filter(gcc_name_2016 == "Greater Melbourne") %>% # let's just look Melbourne
ggplot() +
geom_sf(aes(geometry = geometry)) # use the geometry variable
map
The data also include centroids of each area, and we can add these
points to the map with the cent_lat and cent_long variables using
geom_point.
map <- sa32016 %>%
filter(gcc_name_2016 == "Greater Melbourne") %>% # let's just look Melbourne
ggplot() +
geom_sf(aes(geometry = geometry)) + # use the geometry variable
geom_point(aes(cent_long, cent_lat)) # use the centroid long (x) and lats (y)
map
Cool. But this all looks a bit ugly. We can pretty it up using ggplot
tweaks. See the comments on each line for its objective. Also note that
we’re filling the areas by their areasqkm size, another variable
included in the sf object (we’ll replace this with more interesting
data in the next section).
map <- sa32016 %>%
filter(gcc_name_2016 == "Greater Melbourne") %>% # let's just look Melbourne
ggplot() +
geom_sf(aes(geometry = geometry, # use the geometry variable
fill = areasqkm_2016), # fill by area size
lwd = 0, # remove borders
show.legend = FALSE) + # remove legend
geom_point(aes(cent_long,
cent_lat), # use the centroid long (x) and lats (y)
colour = "white") + # make the points white
theme_void() + # clears other plot elements
coord_sf()
map
Joining with other datasets
At some point, we’ll want to join our spatial data with data-of-interest. The variables in our mapping data—stating the numeric code and name of each area and parent area—will make this relatively easy.
For example: suppose we had a simple dataset of median income by SA3 over time.
# Read data in some data
income <- read_csv("https://raw.githubusercontent.com/wfmackey/absmapsdata/master/img/data/median_income_sa3.csv")
#> Rows: 2148 Columns: 3

#> 4 Goulburn - Mulwaree 2010-11 38269
#> 5 Young - Yass 2010-11 39489
#> 6 Gosford 2010-11 38189
This income data contains a variable sa3_name_2016, and we can use
dplyr::left_join() to combine with our mapping data.
combined_data <- left_join(income,
sa32016,
by = "sa3_name_2016")
Now that we have a tidy dataset with 1) the income data we want to plot, and 2) the geometry of the areas, we can plot income by area:
map <- combined_data %>%
filter(gcc_name_2016 == "Greater Melbourne") %>% # let's just look Melbourne
ggplot() +
geom_sf(aes(geometry = geometry, # use the geometry variable
fill = median_income), # fill by unemployment rate
lwd = 0) + # remove borders
theme_void() + # clears other plot elements
labs(fill = "Median income")

You can use the absmapsdata::get_correspondence_absmaps function to
get population-weighted correspondence tables provided by the
ABS.
Note that while there are lots of correspondence tables, not every
combination is available.
For example:
get_correspondence_absmaps("cd", 2006,
"sa1", 2016)

Why does this package exist?
The motivation for this package is that maps are cool and fun and are,
sometimes, the best way to communicate data. And making maps is R with
ggplot is relatively easy when you have the right object.
Getting the right object is not technically difficult, but requires
research into the best-thing-to-do at each of the following steps:
- Find the ASGS ABS spatial-data page and determine the right file to download.
- Read the shapefile into
Rusing one-of-many import tools. - Convert the object into something usable.
- Clean up any inconsistencies and apply consistent variable naming/values across areas and years.
- Find an appropriate compression function and level to optimise output.
For me at least, finding the correct information and developing the best
set of steps was a little bit interesting but mostly tedious and
annoying. The absmapsdata package holds this data for you, so you can
spend more time making maps, and less time on Stack Overflow, the ABS
website, and lovely-people’s wonderful
blogs.
Comments/complaints/requests
The best avenue is via a Github issue at wfmackey/absmapsdata/issues. This is also the best place to request data that isn’t yet available in the package.
