ASB researchers Glenn Hyman, Efrain Leguia and Konstantin Koenig posed for a quick photograph on the banks of the Ucayali River in Pucallpa, Peru, before heading upstream to the Masisea area. They used digital cameras and global positioning systems to geo-tag their photographs for later use in their land-use validation effort.
During a land-use workshop held 10 days ago in Perú, we developed this guide to geo-tagging digital photos using GPS. I would appreciate any suggestions or comments, especially about other methods and other resources with respect to geo-tagging.
Before REALU’s land-use workshop in the Peruvian Amazon river port city of Pucallpa, Perú during the last week of May, ASB researchers conducted a three-day field campaign to validate their land-use mapping efforts. The purpose of the trip was to verify the map based on what they see on the ground. The researchers linked field notes, global positioning system (GPS) points and digital photographs to support their validation exercise. One outcome of this activity was the development of a guide on how to geo-tag digital photographs. The attached documents in English and Spanish give a step-by-step guide on how to assign the correct geographic coordinates to photographs taken in the field.
