Who We Are

Mark Tukman

After getting his masters in Environmental Management from Duke University in 1995, Mark started his career in GIS working for Dr. Eric S. Kasischke at the Environmental Research Institute of Michigan (ERIM) in Ann Arbor, MI. As part of a grant from the National Science Foundation to study global warming, Dr. Kasischke was using satellite images to map fire scars in the world’s arctic zone.

After one year at ERIM, Mark went to work for a California-based company that was pioneering the use of remote sensing and GIS to map forest land. Pacific Meridian Resource’s visionary founder Kass Green recognized an opportunity to take an academic tool scientists had been experimenting with and apply it to forestry as a production mapping tool. Pacific Meridian was acquired by Space Imaging in the spring of 2000. Mark spent 5 years working for Pacific Meridian/Space Imaging and he managed a number of large land cover mapping projects.

Mark founded Tukman Geospatial in 2003.
