GWIS

Global Wildfire Information System

Overview

The GWIS module provides WMS (Web Map Service) tile URLs for the Global Wildfire Information System and EFFIS (European Forest Fire Information System). These services are part of the Copernicus Emergency Management Service and provide fire danger forecasts, active fire detections, burnt area mapping, and fire severity data.

Basic Usage

using WildfireData.GWIS

# List all layers
GWIS.layers()

# Filter by category
GWIS.layers(category=:active_fires)
GWIS.layers(category=:fire_danger)
GWIS.layers(category=:severity)

# Print general info
GWIS.info()

Building WMS URLs

The primary function is wms_url, which builds WMS GetMap URLs for use with mapping tools or direct image download.

# Get VIIRS hotspots for Europe, last 7 days
url = GWIS.wms_url(:viirs_hotspots, bbox=(-25, 27, 45, 72), days=7)

# Get Fire Weather Index for the Mediterranean
url = GWIS.wms_url(:fwi, bbox=(-10, 30, 40, 50))

# Get MODIS burnt areas for the full fire season
url = GWIS.wms_url(:modis_burnt_areas, bbox=(-25, 27, 45, 72), days=0)

# Custom image size
url = GWIS.wms_url(:fwi, width=2048, height=1024)

Downloading Map Tiles

# Download a WMS tile image
path = GWIS.download_tile(:viirs_hotspots, bbox=(-25, 27, 45, 72), days=7)

# Force re-download
path = GWIS.download_tile(:fwi, bbox=(-10, 30, 40, 50), force=true)

# Custom filename
path = GWIS.download_tile(:fwi, filename="mediterranean_fwi.png",
    bbox=(-10, 30, 40, 50))
