He graduated from UC Berkeley in 2017 with a bachelor’s degree in Environmental Sciences and Forestry, and he is currently working toward a certificate in Geographic Information Systems Technology at Foothill College.
Tyler McCarthy
GIS Analyst
After growing up in Sonoma County, Tyler attended University of Washington where he received a B.S. in Environmental Science and Terrestrial Resource Management. After graduating, and a brief stint as a GIS intern in the wine industry, Tyler joined Tukman Geospatial where he is continuing to grow his skills as an analyst and mapper.
Laura Askim
Vegetation Mapper
Laura has been conducting botanical surveys since she attended UC Davis with a degree in Ecological Management and Restoration, graduating in 2010. Since 2012, she has been working as a vegetation mapping analyst. Her mapping projects and associated field surveys have covered a wide expanse of California, with an emphasis on the Modoc Plateau, Central Valley, Central Coast, and Suisun Marsh.
Brian Kreb
Vegetation Mapper
Brian is a born and raised Californian, who left the Bay Area to attend Chico State University in the early 90’s. There he attained a Bachelor’s degree in Environmental Geography, with a Business minor and a certificate in Geographic Information Systems. For 10 years, he worked as a fisheries biologist on the Feather, Sacramento, and Yuba Rivers and several tributaries. Since 2010, Brian has been dedicated to vegetation mapping and was the lead biologist and project manager for several mapping projects throughout the state including the Great Valley Ecoregion, Delta, Suisun Marsh, High Speed Rail Corridor, and much of Plumas, Modoc, and Lassen counties. He is excited to continue California vegetation mapping with Tukman Geospatial.
Partners
Kass Green
Owner, Kass Green and Associates
Kass is a key partner and adviser and her vision (and elbow grease) is evident in many of Tukman Geospatial's projects and map products. Kass's experience spans thirty years of managing and supervising GIS and remote sensing professionals, as well as leadership in GIS and remote sensing research and policy. As a non-tiring advocate of the Landsat, Ms. Green has testified before Congress and worked on numerous initiatives to support the Landsat Program. Her research includes innovations in automated change detection and object oriented image classification. Ms. Green chairs NASA’s Earth Science Applications Committee, co-founded and chaired the Department of the Interior’s Landsat Advisory Group and has served on a variety of Federal Advisory Committees for NASA, NOAA and DOI. She has taught numerous workshops for ASPRS and federal agencies, is a fellow and an honorary member in the American Society of Photogrammetry and Remote Sensing (ASPRS), and a past president of both MAPPS and ASPRS.
Kyle Christie
Botanist
Kyle is a botanist and has worked with Tukman Geospatial as a science adviser and on a number of vegetation mapping projects. Kyle has worked across California and the Southwest collecting field vegetation data for the National Park Service and private industry. Kyle completed a Master’s degree at Northern Arizona University in 2006, where he explored floristics, local scale vegetation shifts across an edaphic gradient, and regional phtyogeographical affinities of Pinyon-Juniper woodlands on the Colorado Plateau. For his PhD from UC Davis, Kyle is currently studying mechanisms of speciation in the plant clade Streptanthus (s.l., Brassicaceae). Kyle continues to work with Tukman Geospatial, especially during field season.
