Ian McCallum

Ian McCallum is a researcher in the Ecosystem Services & Management (ESM) Program at the International Institute for Applied Systems Analysis (IIASA) in Austria. He holds a graduate degree in Forest Science from Lakehead University in Canada, where he specialized in the application of geographic information systems and remote sensing. Prior to joining IIASA he worked for both forest industry and forest consulting firms in central and western Canada.

Since joining IIASA he has contributed to numerous research projects applying geo-spatial analysis to global environmental problems. Topics range from biomass estimation to carbon accounting and modeling to global land cover validation, with a focus on northern Eurasia. He is an active member of the Geo-Wiki team, applying crowd-sourcing tools to improve global environmental datasets.

Further research efforts revolve around the Group on Earth Observations (GEO), where he co-leads the GEO Task ID-03 which focuses particularly on the incentives to join the Global Earth Observation System of Systems (GEOSS). Furthermore he has participated in research aiming to demonstrate the benefits we derive from Earth Observations.
