wdpa_read {wdpar}

Read data

Description

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).

Usage

wdpa_read(x, n = NULL)

Arguments

x

character file name for a zip archive file downloaded from https://www.protectedplanet.net/en.

n

integer number of records to import per data source. Defaults to NULL such that all data are imported.

Details

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()).

Value

sf::sf() object.

Data source

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. For more details on data conventions, please consult the official manual (UNEP-WCMC 2019).
