Leila Gass
I’m an ecologist and geographer, working with the Western Geographic Science Center.
My primary interest and expertise is in using GIS and remotely-sensed imagery to analyze spatial patterns and relationships on the landscape. Current and previous projects include modeling land cover change and assessing accuracy for the National Land Cover Database (mrlc.gov); producing spatial data for a world-wide assessment of potash resources and for a mineral assessment of the Greater Antilles; and species distribution modeling for desert tortoises.
