In troyhill/fireHydro: FireHydro tool

fireHydro

What you have here

fireHydro is an R package that estimates fire spread risk in south Florida by integrating diverse datasets: 1. water level data sourced from USGS/EDEN 2. vegetation cover maps classified by University of Georgia and categorized into litter classes using the professional judgement of Everglades National Park's Fire Cache group 3. the spatial extent of historical burns over the preceding three years

fireHydro installation

install.packages("devtools")
devtools::install_github("troyhill/fireHydro")

fireHydro usage

fireHydro can be used to create shapefiles and/or images providing an integrative measure of fire risk in Big Cypress National Preserve and Everglades National Park.

library(fireHydro)

### the EDEN web scraper defaults to downloading the most recent EDEN water depth data
edenDat <- getEDEN()

### getEDEN() output can then be used directly in getFireHydro()
fireDat <- getFireHydro(EDEN_date = edenDat$date, 
     EDEN_GIS_directory = edenDat$data,
     fireSpreadExport = c("fireRisk.png", "fireRisk.pdf"), # multiple outputs can be created simultaneously
     waterLevelExport = c("waterLevels.png", "waterLevels.pdf"))

Output example: Current water levels
