Tools

As tracking technologies advance, there is a growing need for analytical tools that can unlock the information contained in large, high-resolution datasets. In response, Smithsonian scientists have created open-source analytical tools that help scientists and practitioners make informed conservation decisions from animal movement datasets.

Continuous-Time Movement Modeling
Continuous-Time Movement Modeling

ctmm is an open-source software package for analyzing animal tracking data. It models animal movement as a continuous-time stochastic process to provide more accurate estimates of home-range size, energy expenditure and encounter rates in a convenient R package.

ctmmweb
ctmmweb

ctmmweb is a user-friendly graphical interface for ctmm, designed for wildlife managers and conservation practitioners. It takes many of the most popular functions from the ctmm R package and makes them more accessible to users without coding experience.
