These datasets represent the outputs from short and long-range wildfire exposure assessments, which quantify the proportion of surrounding grid cells containing hazardous fuels for a given location. The long-range exposure dataset identifies the number of cells within a 500m radius with the potential to generate embers that could reach that location, while the short-range exposure dataset evaluates the number of cells within a 100m radius with a similar ember-generating potential.
The directional vulnerability datasets assess linear wildfire vulnerability on the landscape in a systematic radial sampling pattern based on intersection with areas of high exposure, indicating the direction and extend of potential wildfire pathways towards a value (communities).
This dataset was generated using the FireexposuR package for R (GitHub - ropensci/fireexposuR: Compute and Visualize Wildfire Exposure)
The short- and long-range exposure datasets were generated using a 2020 LANDSAT land classification dataset. Fire perimeters from between 2020 and 2025 were incorporated into the land classification raster using a mosaic tool. The dataset was then reclassified to values between 0 and 1 to represent the potential for each land cover type to produce embers that travel 100 m (short-range) and 500 m (long-range). The following classification matrices were used. Land cover types marked as 1 indicate the potential to generate embers that travel the required distance, while those marked as 0 indicate no potential to generate embers that travel the required distance:
Long-Range (500 m) exposure
1, # Temperate or subpolar needleleaf forest
