Description:
Abstract:
This coverage represents year 2020 MODIS fire detections for the geographic area covering the provinces and territories of Canada including a 50km buffer around the periphery. The detections are obtained using both TERRA MODIS and AQUA MODIS data are collected and processed as a cooperative effort between the USDA Forest Service Geospatial Technology and Applications Center, NASA-Goddard Space Flight Center and the University of Maryland.
Purpose:
These fire detection data are collected for the USDA Forest Service MODIS Active Fire Mapping Program (https://fsapps.nwcg.gov/afm). These data are intended to provide a synoptic view of active fires for the past and present over the specified time period. These data are collected at a spatial resolution of 1 kilometer and therefore are only intended for geographic display and analysis at the national and regional levels. No responsibility is assumed by the USDA Forest Service in the use of these data.

Use_Constraints:
These data are updated daily throughout the year, therefore it is recommended that users reacquire the data from the USDA Forest Service as necessary. The dataset is current through the Julian date and time stamp specified. For example, modis_fire_2020_101.e00.gz means that the data set is current through day 101 of the year 2020 (April 11, 2020). Acknowledgement of the USDA Forest Service Geospatial Technology and Applications Center would be appreciated in products derived from these data.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
Point attributes are derived from the MODLand Rapid Response algorithm and are subject to caveats and known problems documented in the MOD14 Fire Products Users Guide (<http://modis-fire.umd.edu/>)
Logical_Consistency_Report:
TERRA and AQUA MODIS provide complete coverage of the mid to higher latitudes four times daily. TERRA MODIS acquires data twice daily crossing the equator on an ascending node at 10:30 AM (local time) and also on a descending node at 10:30 PM. AQUA MODIS also acquires data twice daily crossing the equator on an ascending node at 1:30 PM (local time) and also on a descending node at 1:30 AM. MODIS data are acquired for the majority of the United States and southern Canada in near real time at the USDA Forest Service Geospatial Technology and Applications Center (GTAC) in Salt Lake City. MODIS data for the eastern United States, Alaska, Hawaii and the rest of Canada are acquired near real-time from other selected MODIS ground stations and the NASA Goddard Space Flight Center (GSFC) MODIS Rapid Response System. MODIS data are processed within minutes of acquisition at GTAC, other MODIS ground stations and GSFC to extract active fire locations.
Completeness_Report:
The fire detections are discerned using the 1 kilometer thermal bands of MODIS. Fire locations are extracted from daily MODIS data by the MODLand Rapid Response System using the algorithm described by the MOD14 Users Guide (<http://modis-fire.umd.edu/>). Detections are provided as the centroids of the 1 kilometer pixels and compiled into daily Arc/INFO point coverages. Identification of a MODIS pixel as "fire" does not necessarily mean that the entire area represented by the pixel is on fire. 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. At this time, there is no way to discriminate between these two possibilities.

Fires as small as 100 square meters burning at a temperature of 1500 degrees Farenheit may be detected by MODIS. However, cloud cover above the fire, or, the position of the fire on the terrain relative to the location of the MODIS sensor may preclude the ability for detection.

Fire detection points represent the centroid of the 1 kilometer cell for a fire detection. Points are accurate to +/- 50 meters.

MODIS active fire detections derived from MODLand Rapid Response used for USDA Forest Service MODIS Active Fire Mapping
Process_Step:
Process_Description:
Original MODIS fire detections were created through the following steps:

1) Processed raw output from MODLand Rapid Response Fire Detection algorithm and imported into daily Arc/INFO coverages.

2) Reprojected MODIS active fire detection coverages from WGS84 to NAD83 (Projected data from WGS84 to NAR_C - essentially NAD83).
