Burned-area time series for a polygon (% of range x year)

Source: R/fire.R
fire_timeseries.Rd

Fire analogue of cover_timeseries: reads the annual burned layer for each year and returns burned area (km^2) and percentage of the range. Each year is one windowed read, so a full annual series can be slow.

Usage

fire_timeseries(
  geom,
  years = NULL,
  fire_collection = 4,
  host_collection = 9,
  range_km2 = NULL,
  verbose = TRUE
)

Arguments

geom

An sf/sfc polygon.

years

Integer vector (default mb_years()).

fire_collection

Fire collection number (default 4).

host_collection

Initiative folder hosting the fire data (default 9; Fire Col.4 lives under collection_9/).

range_km2

Range area for the percentage denominator (optional).

verbose

Logical; print progress.

Value

A data.frame with year, burned_km2, burned_pct.
