To estimate the real extent of the problem, the organizers have created garbage mapping software - so that with the help of volunteers all the illegal dumping places can be put on the country map - with exact locations and other relevant data. This serves well when planning the actual clean-up day - to estimate necessary resources, plan the action of volunteers and logistics. But mapping is also a great tool to really raise the dumping issue into the limelight - once it's in front of your eyes there can be no denial anymore.
