Estimation of Tree Height in Burned Areas with GEDI Laser Data in Northern Portugal and Galicia (Spain)
We analyzed the tree height of four areas affected by wildfires in northern Portugal and Galicia (Spain) using the GEE platform, random forest regression model, and GEDI data. Before the fires, the heights varied from 5.21 to 20.16 m, with r<sup>2</sup> values of 0.82 and 0.67. After the...

Summary: | We analyzed the tree height of four areas affected by wildfires in northern Portugal and Galicia (Spain) using the GEE platform, random forest regression model, and GEDI data. Before the fires, the heights varied from 5.21 to 20.16 m, with r<sup>2</sup> values of 0.82 and 0.67. After the fires, heights of 5.55 to 9.12 m were recorded, with values of r<sup>2</sup> 0.47 and 1. These r<sup>2</sup> values after fires indicate the absence or limitation of sample data. We concluded that the GEDI data have great potential to assist in the mapping of areas affected by wildfires. |
