Welcome to the dsm wiki!

dsm is a package to model the spatial distribution of animals using data collected from a distance sampling (amongst others) survey. DSM stands for density surface model, though we often use such models to calculate abundance the name has stuck.

dsm is an R package and is designed to be used with mrds or Distance.

Getting the latest version of dsm

CRAN only allows packages to be updated infrequently (due to them having to be checked by hand). I often make fixes more frequently (and then often forget to update the CRAN package).

To ensure you have the latest version of dsm, install devtools:


then install dsm from github:


Then you have a shiny new version of dsm on your computer.

You can’t perform that action at this time.
