Fires

When you select Fires as your overlay layer, it will match the corresponding fire layer to the base layer you have picked. These are available approximately 3 hours after satellite observation.
  • Terra/MODIS Corrected Reflectance layers: Terra/MODIS Fires and Thermal Anomalies (Day and Night) layer (8 May 2012 - present)
  • Aqua/MODIS Corrected Reflectance layers: Aqua/MODIS Fires and Thermal Anomalies (Day and Night) layer (8 May 2012 - present)
  • Suomi-NPP/VIIRS Corrected Reflectance layers: Suomi-NPP/VIIRS Fires and Thermal Anomalies (Day) layer (25 November 2015 - present)
  • Suomi NPP, VIIRS, Black Marble Nighttime At Sensor Radiance (Day/Night Band): Suomi-NPP/VIIRS Fires and Thermal Anomalies (Night) layer (18 November 2020 - Present)
  • Suomi NPP, VIIRS, Black Marble Nighttime Blue/Yellow Composite (Day/Night Band): Suomi-NPP/VIIRS Fires and Thermal Anomalies (Night) layer (30 April 2021 - present)
  • Suomi-NPP/VIIRS Day/Night Band, ENCC: Suomi-NPP/VIIRS Fires and Thermal Anomalies (Night) layer (25 November 2015 - present)
  • NOAA-20/VIIRS Corrected Reflectance layers: NOAA-20/VIIRS Fires and Thermal Anomalies (Day) layer (24 April 2020 - present)

Coastlines

The Coastlines layer is a vector layer displaying global coastlines. Coastlines information are gleaned from OpenStreetMap.

Coastlines, Borders and Roads

The Coastlines/Borders/Roads layer is a vector layer displaying global coastlines, country borders, first order administrative boundaries and major roads. Coastlines/Borders/Roads information are gleaned from OpenStreetMap and Natural Earth.
