Q: What is the blue pin (iOS) or blue crosshairs (Android) for? How do I lookup weather for a specific location on the map?

iOS: The blue pin is a point of reference for the "Map Tools" side menu tray. The blue pin tracks your slewing motions, zoom motions, and always centers itself. It is also draggable. Using slewing and zoom, center the blue pin on the map next to a fire to do a hyper-local weather lookup from the Map Tools side menu tray, to make a measurement, to center an external Google or Apple Map, to lookup GOES satellite imagery, etc. at the location of the blue pin.

Android: The blue crosshairs is also a point of reference for the "Map Tools" side menu tray. Just like on iOS above, but not draggable. Using slewing and zoom, center the location you want the hyper-local weather for in the crosshairs.

MODIS and VIIRS are NASA satellite instruments that measure thermal hotspots, there is some lag depending on luck because of the orbit/track/scan.

The MODIS & VIIRS thermal hotspots are color coded by day. If there are two days reported, Red pins are from the current day in UTC. Purple pins are from the prior day in UTC. If there is just one day reported, trust the color used and timestamps. Tap any of these hotspot pins to see more details including brightness, power, and timestamp.

MODIS & VIIRS data can be up to 24 hours old.

MODIS resolution: 1 km
VIIRS resolution: 375 m

WFIGS/IRWIN Current Wildfire Perimeters WFIGS: Wildland Fire Interagency Geospatial Services and IRWIN: Integrated Reporting of Wildland Fire Information. These services are not "live". They are updated from operational data and may not reflect current conditions on the ground. New data is pulled every 20 minutes for the purposes of this app. On a weekly basis, fires meeting specific criteria are removed by WFIGS/IRWIN.

The InciWeb Incidents Feed is sorted alphabetically by state first, then by fire name.

The InciWeb Articles Feed is sorted in chronological order, not by state.

InciWeb is an interagency incident system provided by the United States Forest Service.
