Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Conference Paper Description
This paper presents a case study of wildland fire rate of spread estimation using an autonomous unmanned aerial system (UAS), deployed in a prescribed burn conducted in the Zaleski State Forest in South Ohio. In recent years, UAS have seen increasing use to measure the fire perimeter in active wildland burns. In this case study, we build and deploy a small UAS platform equipped with infrared sensing to measure the rate of spread of the fire front in a prescribed burn conducted in a forest environment with significant topographic expression. Infrared data retrieved from the experiment is re-projected into the three-dimensional world frame, followed by a novel geometrical analysis of the observed fire intensity contours. A Delaunay triangulation is conducted to discretize the space around time-separated fire fronts, resulting in local rate of spread estimates based on fire intensity gradients. The infrared databased rate of spread estimates are compared against the output of a widely used fire behavior model called the Rothermel model. While the data-based calculations show a good match with the Rothermel model’s mean predictions, the latter is shown to exhibit large sensitivity to topographic and environmental parameters, especially slope steepness of the terrain.
