Groundtruthing: A Note on Methodology

An overview of Groundtruthing – a methodology for comparing facts stated in official documents and maps with the ground realities at a site or in a place. Groundtruthing can act as an effective tool to create evidence by collecting easily observable facts about operations that might be illegal, prohibited or causing harm. The evidence can be used in complaints directed to the relevant regulatory authority, appellate mechanism or judicial body. This method is useful for one-time investigations or the ongoing monitoring of impacts.
