Geographic information systems (GIS) are transforming our knowledge and understanding of what goes on across the surface of our planet. While most of us are familiar with some basic GIS tools through applications like Google Maps, with advances in cloud and mobile technology GIS is being used in an ever wider range of fields. In the world of standards and certification, GIS presents an opportunity to make audits more effective and efficient. It can also be a powerful means for assessing the performance and impact of certification schemes, for example by tracking changes in forest cover.
