Leila Gass


I’m an ecologist and GIS analyst, currently working with the Western Geographic Science Center in Tucson, Arizona.  

My primary interest and expertise is in using GIS and remotely-sensed imagery to analyze spatial patterns and relationships in ecological systems. Current and previous projects include modeling land cover change and assessing accuracy for the National Land Cover Database (NLCD); producing spatial data for a world-wide assessment of potash resources and for a national moneral assessment for Cuba; and species distribution modeling for desert tortoises. My work includes project proposals, literature reviews, data compilation, database design and analysis, poster design, and report writing and editing.
