Quick determination of the area of the burned forest or field caused by the fire is important when estimating losses, monitoring the rebirth of vegetation on the site of fire and planning strategies for forest reconstruction. In order to provide quick information about the area burned by large fires, the BAI index (Burn Area index) is used. This index is obtained using optical methods of satellite remote sensing. In Poland, most fires are the fires of soil cover, the area of which does not exceed 1 ha. In such cases, the use of satellite technology is not applicable due to a number of limitations that are discussed in the text. The article presents the possibility of using the BAI index from a small height. Since the BAI index was originally used for satellite measurements, the article discusses the differences in ground measurements. Experimental research has been described and results from controlled firing have been presented.
