dgg_extract: Extract raster data with a DGG shapefile

In nick-gauthier/anthromes-12k: Tools for Analyzing Long-Term Population and Land Use

Extract raster data with a DGG shapefile

Description

Given a stars data object and shapefile, extracts the relevant data using exactextractr::exact_extract(). Stars inputs should be in raster format with x and y dimensions. This function is planned for deprecation whenever direct support for exact_extract() is better supported via stars::aggregate().

Usage

dgg_extract(dat, dgg, var = NULL, fun, progress = FALSE)

Arguments

dat	The raster data to extract.
dgg	Shapefile containing the DGG boundaries to use for the extraction.
var	The variable to extract.
fun	The function to pass to exactextractr::exact_extract().
progress	Display the exactextractr::exact_extract() progress bar.

Examples

dgg_extract(hyde_med, dgg_med, 'crops', 'sum')
