{ "currentVersion": 10.91, "id": 81, "name": "Fire History", "type": "Feature Layer", "description": "This dataset contains fire history data for the Northwest Territories dating back to 1965. From 1965 to 1985 the data is exclusively based on data collected from the fire management agency at the time. Starting in 1986 the data used is based on the most appropriate source from either agency collected data, the MAFiMS algortihm (using higher resolution imagery from sensors like Landsat 8 or Sentinel 2) or the HANDS algorithm (which uses coarse imagery from SPOT). Where possible the water and unburned green areas have been removed from fire polygon areas to improve the accuracy of fire perimeters. Water and unburned areas were only systematically removed from perimeters that are more recent than 1985.", "geometryType": "esriGeometryPolygon", "sourceSpatialReference": { "wkid": 102002, "latestWkid": 102002 }, "copyrightText": "This layer was developed by Matthew Coyle, Fire Geomatics Analyst for the Northwest Territories.
