 It can detect specific types of foliage supporting drug-crop identification; disturbed soil supporting the identification of mass graves, minefields, caches, underground facilities or cut foliage; and variances in soil, foliage, and hydrologic features often supporting NBC contaminant detection.This was done previously with false-color infrared photographic film, but electronics are faster and more flexible.JHU/APL target-detection algorithms have been applied to the Army Wide Area Airborne Minefield Detection (WAAMD) program's desert and forest.
