Create fire regime polygons for scfmRegime.
Usage
fireRegimePolyTypes()
prepInputsFireRegimePolys(
url = NULL,
destinationPath = tempdir(),
studyArea = NULL,
rasterToMatch = NULL,
type = "ECOREGION"
)Arguments
- url
character. URL from which to download and prepare fire regime polygons. Defaults are provided for Canadian ecodistrict, ecoregion, ecoprovince, and ecozone, as well as national Fire Regime Types and Fire Regime Units from Erni et al. (2020) doi:10.1139/cjfr-2019-0191 .
- destinationPath
character. Path to directory where data will be downloaded.
- studyArea
sfobject corresponding to the study area of interest.- rasterToMatch
TODO
- type
character. The polygon type to use: Must be one of "ECODISTRICT", "ECOREGION" (default), "ECOPROVINCE", "ECOZONE", "FRT", or "FRU". If
urlto BEC shapefile is provided, can also be one of: "BECNDT", "BECSUBZONE", or "BECZONE".
