The MapNat tool is designed to be applied by citizens and scientists who are interested in mapping the use of mainly cultural, but also some provisional and regulating, services and disservices. MapNat enables its users to map ES in three different ways as points, lines or areas on a map on their phone. Once the user selects a location, he/she is guided to a list to select the ES which are being used. Users can deliver additional information, e.g. about the vegetation, or provide comments or a photograph. Mapped uses are immediately visible on the map display, which also shows the records of all other users displayed in different colors, depending on the type of ES or disservice.
