Read data obtained from Protected Planet. Specifically, this function is designed to import data obtained from the World Database on Protected Areas (WDPA) and the World Database on Other Effective Area-Based Conservation Measures (WDOECM).
wdpa_read(x, n = NULL)
character
file name for a zip archive file downloaded from
https://www.protectedplanet.net/en.
integer
number of records to import per data source.
Defaults to NULL
such that all data are imported.
sf::sf()
object.
This function assumes that data have previously been downloaded to
your computer, and need to import the data.
After importing the data, it is strongly recommended to clean the data
prior to analysis (see wdpa_clean()
).
The PA_DEF
column indicates the data source for individual
areas and sites that comprise the imported dataset.
Specifically, data obtained through the World Database on Protected Areas
(WDPA) are indicated with a value of 1
in the PA_DEF
column.
Additionally, data obtained through the World Database on Other Effective
Area-Based Conservation Measures (WDOECM) are indicated with a value of 0
in the PA_DEF
column.
