Do you experience odour nuisance? The Odourapp is intended for mapping odours caused by industry, but also for odours released around, for example, agriculture, livestock farming and waste processing activities. You can use your current location and time or manually indicate a location and time where and when you smelled the odour. In the app you indicate which odour you have smelled by choosing from a number of options and determining the intensity. Once you have entered the location, time and odour you can send the notification. We use this information to link odour observations to other data sources for mapping odour nuisance.
