However, in actual practice, fire distance and location were normally established using two or more Fire Finder-equipped towers, using the intersection method to fix the precise location of the fire.<ref>Guth, Peter, (Prof.), Craven, Tom, Chester, Tom, Shotwell, Jim, and O'Leary, Zeyn, '[https://web.archive.org/web/20111006122337/https://courseware.e-education.psu.edu/downloads/geog884/guth_others_2005_asprs_conf.pdf 'Fire Locations From A Single Osborne Fire Finder and a DEM], Report to the ASPRS 2005 Annual Conference “Geospatial Goes Global: From Your Neighborhood to the Whole Planet”, Baltimore, MD (7–11 March 2005), pp.
In real-world applications, fire distance and location are typically determined using multiple Fire Finder-equipped towers, employing the intersection method to pinpoint the precise location of the fire.
