Description
The lidar Topographic Wetness Index (TWI) is the TWI data product produced and distributed by the National Park Service, Great Smoky Mountains National Park. Concave, low gradient areas will gather water (low TWI values), whereas steep, convex areas will shed water (high TWI values). Values range range from less than 1 (dry cells) to greater than 20 (wet cells).
