Guillermo Castilla, Ph.D.

Remote Sensing Research Scientist
Natural Resources Canada

Current research and/or projects

I am a remote sensing research scientist at the Northern Forestry Centre of Natural Resources Canada. I integrate geospatial technologies to map and monitor land cover, forest structure and composition, and natural (e.g., fire, insect outbreaks) and anthropogenic (forestry, oil and gas) disturbances in support of forest ecosystems and climate change science and policy.

Research and/or project statements

Current Research Projects:

  • Development of a framework for monitoring reclamation along seismic lines.
  • Geospatial technologies for monitoring vegetation recovery on human disturbance features in Alberta’s boreal forest.
  • Monitoring of northern Canada’s boreal forests through multi-source remote sensing.
  • National Burned Area Composite (NBAC).

Professional activities / interests

  • Land cover mapping.
  • Change detection.
  • Accuracy assessment.
  • Object-based image analysis.
  • Other activity: Supervision of one student from the University of Calgary and professionnal staff.
