Here you can find the exercises for the practical sessions during the course. All content will remain here on the Distance website for future consultation.
Note that the practicals are designed to be run sequentially, files generated from previous analyses are loaded and used in subsequent analyses.

Data for the practicals come in a variety of forms for analysis both in R and in Distance 7.
Data for density surface modelling (Practicals 2-7)
To run the sperm whale analysis you’ll need to download the following files, unzip them and store the unzipped folders in the same directory as the
Rmd files for practicals 5-10 above:
The Distance 7 project containing these data can be downloaded from this location
We’d like to thank Jason Roberts of Duke University for preparing these files in ArcGIS with the MGET Toolbox.
Data for double platform analysis (Practical 8)
For R users you just need the
