A software application for mapping livestock waste odour dispersion

OdiGauss is a free multilingual software application allowing to estimate odour dispersion from multiple point sources and to generate the related maps. Dispersion is calculated according to a Gaussian approach, as a function of wind speed and direction, precipitation, temperature, and solar radiation. OdiGauss incorporates a model of odour emissions from poultry farms (EmiFarm) which makes predictions based on manure production and management. Two case studies of software application on real poultry and swine farms are presented.
