roads - Road Network Projection

Iterative least cost path and minimum spanning tree methods for projecting forest road networks. The methods connect a set of target points to an existing road network using 'igraph' <https://igraph.org> to identify least cost routes. The cost of constructing a road segment between adjacent pixels is determined by a user supplied weight raster and a weight function; options include the average of adjacent weight raster values, and a function of the elevation differences between adjacent cells that penalizes steep grades. These road network projection methods are intended for integration into R workflows and modelling frameworks used for forecasting forest change, and can be applied over multiple time-steps without rebuilding a graph at each time-step.

bboudata - Data for bbou Project

This package contains boreal caribou demographic data which can be used as validation for the associated shiny-app and analysis. The overall goal of the bbou packages is to develop a more standardized and consistent method for the comparison of boreal caribou survival rates, recruitment and population dynamics across Canada.

bbousuite - Easily Install and Load `bbou` (Boreal cariBOU) Packages

The `bbou` suite of packages are designed to allow analysis (`bbouretro` and `bboutools`) and simulation (`bbousims`) of Boreal Caribou survival and recruitment data ('bboudata') to estimate population growth rates. A shiny app is also available (`bboushiny`).
