Timothy Warner


Tim specializes in remote sensing applications and the spatial analysis of images. He utilizes optical and thermal imagery, as well as lidar, to study terrestrial features including biogeographical and geological phenomena.

Remote Sensing Laboratory

PI: Tim Warner, Professor of Geography and Geology


I have broad interests in remote sensing, including the spatial properties of images, lidar data, thermal imagery, machine learning, and information literacy. Much of my recent work has focused on time-series analysis of remotely sensed data. I am currently working on multi-temporal lidar for mapping widlfire fuel consumption. I have a particular interest in the use of remote sensing for promoting nuclear transparency and non-proliferation.
