DESCRIPTION

An effort to assess the relationship and potential synergies of individual-based ecology and remote sensing, and to identify some of the specific challenges of gathering remote-sensing data to develop individual-based ecological theories. An accompanying paper is at http://hughstimson.org/projects/rsibe

“The study of ecological systems from the perspective that systems arise from unique independent, individuals and the interactions of the individuals with each other and with their environment.”
