Download the National Burn Area Composite (Fires) in Canada

Description

Downloads data from CWFIS Datamart at http://cwfis.cfs.nrcan.gc.ca/datamart. This runs prepInputs internally, so use can pass studyArea etc.

Usage

prepFireCanada(
  year,
  type = c("NBAC", "Polygon", "Point"),
  urlBase = "http://cwfis.cfs.nrcan.gc.ca/downloads/nbac/",
  ...
)

Arguments

year	Numeric, length 1. Which year, from 1986 to 2018 (currently) to download
type	Either "NBAC", "Polygon" or "Point" to get the National Burn Area Composite, the Polygon or the Point datasets.
urlBase	The url of the directory where the NBAC are stored. Default is the currently known url. If this url becomes stale, please notify the predictive ecology team.
...	Additional arguments.

Value

A SpatialPolygonsDataFrame plus several downloaded files, including the ‘.zip’ archive and the extracted files. Because it is running prepInputs, checksumming is occurring too.
