Seán Lynch started researching litter mapping in 2008 when introduced to GIS in University. After working as a divemaster in the tropics, he came home and did two MSc to develop citizen science methodologies. He then taught himself to code and launched OpenLitterMap in April 2017 which has now been used by over 4000 people in 80 countries. He recently invested in a training rig and currently using OpenLitterMap 150,000+ images with manually verified tags to train the OpenLitterAI. He has many more plans to develop the open citizen science economy which has huge global potential but remains largely unexplored.
