Read, Explore and Visualize Camera Trap Data Packages • camtraptor

Camtraptor is an R package to read, explore and visualize Camera Trap Data Packages (Camtrap DP). Camtrap DP is a community developed data exchange format for this type of data. With camtraptor you can read and filter data, create overviews of observed species, relative abundance or effort, and plot these data on a map.

To get started, see:

Vignettes: tutorials showcasing functionality.
Function reference: overview of all functions.

Installation

You can install the development version of camtraptor from GitHub with:

# install.packages("devtools")
devtools::install_github("inbo/camtraptor")

While we support older versions of R up to 3.5, we recommend using R 4.0.0 or higher.

Filter observations in mica on female mallards and map the number of individuals per deployment location:

map_dep(
  mica,
  feature = "n_individuals",
  species = "Anas platyrhynchos",
  sex = "female"
)
#> There are 4 deployments without observations: 29b7d356-4bb4-4ec4-b792-2af5cc32efa8, 577b543a-2cf1-4b23-b6d2-cda7e2eac372, 62c200a9-0e03-4495-bcd8-032944f6f5a1 and 7ca633fa-64f8-4cfc-a628-6b0c419056d7

camtraptor vs camtrapR and activity

Camtraptor provides and bundles much needed functionality to read, explore and visualize Camera Trap Data Packages. Over time we hope to include some or all of this functionality in widely used R packages such as camtrapR and activity.
