CalFire and others use this same data to help identify fires and their hot spots. The hot spots are an approximation and do not include all areas affected by fire, nor do they indicate with certainty an area was affected. Hot spots are locations identified by satellite analysts from the National Oceanic and Atmospheric Administration (NOAA). VIIRS-I also has improved nighttime performance. The 375-meter spatial resolution provides a greater response over fires of relatively small areas and provides improved mapping of large fire perimeters. The Visible Infrared Imaging Radiometer Suite (VIIRS-I) provides data from sensors aboard the joint NASA/NOAA Suomi National Polar-orbiting Partnership satellite. At this time, there is no way to discriminate between these two possibilities. The identification of a fire can be the result of a hot fire in a relatively small area or a cooler fire over a larger area. The identification of a "fire" by MODIS does not necessarily mean the entire area represented is on fire. Thermal information is collected at 1,000-meter spatial resolution. The Moderate Resolution Imaging Spectroradiometer (MODIS) displays fire detection data and uses fire and thermal anomalies data compiled via MODIS satellites Terra and Aqua. But because of the distance of the satellites, the nature of the measurements and obfuscation by smoke, the resolution is coarse and not 100 percent accurate. CalFire and others use this data to help identify fires and their hot spots. They are an approximation and do not include all areas affected by fire, nor do they indicate with certainty an area was affected. The perimeters are intended to provide a picture of the scope and extent of the fires in California, as well as parts of Nevada and Oregon, with the most current data possible. Perimeters are not available for every incident.įire perimeters for incidents before Jare based on infrared and thermal imaging from NASA's MODIS and VIIRS-I products. Perimeters do not include prescribed or incident complex fires. This map displays all current wildfire fire perimeters available through NIFC that have not been 100% contained. Fire Perimetersįire perimeters are based on geographic data from the National Interagency Fire Center, updated once an hour.

We’ll pay the most attention to the new stuff, but we’ll also detail each and every one of OS X Server’s services, explaining what it does, how to use it, and where to find more information about it. As with our pieces on Mavericks and Mountain Lion, this article should be thought of as less of a review and more of a guided tour through everything you can do with OS X Server. Still, the Yosemite version of OS X Server changes enough to be worth revisiting. But now OS X Server is changing very little from version to version, and since the untimely death of the Mac Mini Server, Apple isn't even selling any kind of server-oriented hardware. The software hasn’t grown stagnant, really-certainly not to the extent of something like Apple Remote Desktop, which only gets updated when it’s time to support a new OS X version. That much was clear when Mavericks Server came out a year ago with just a handful of welcome-but-minor tweaks and improvements.
