makeLociList: Convert a list of 'SpatialPointsDataFrame' object to a list...

In PredictiveEcology/fireSenseUtils: Utilities for Working With the 'fireSense' Group of 'SpaDES' Modules

Description

Must supply a raster so that points can be converted to the cells on a raster. It is assumed that the sizeCol is accurate. If not, it should be recalculated before this function call.

Usage

makeLociList(
  ras,
  pts,
  idsCol = "NFIREID",
  dateCol = "YEAR",
  sizeCol = "POLY_HA",
  sizeColUnits = "ha"
)

Arguments

ras	A raster that will be the template for cells (pixel ids)
pts	A list of SpatialPointsDataFrame objects
idsCol	Character string identifying column name in pts that has unique id per event (i.e., fire)
dateCol	Character string identifying column name in pts that has year
sizeCol	Character string identifying column name in pts that has size of individual event. Can be in hectares or metres squared. Should set sizeColUnits
sizeColUnits	Character string. Either "ha" or "m2".

Value

A list of data.table objects, each with 4 columns, "size" (in pixels), "date", "ids" from idsCol, and "cells", which are the pixel indices of the pts points.
