read_camtrapdp: Read a Camera Trap Data Package

In inbo/camtrapdp: Read and Manipulate Camera Trap Data Packages

Read a Camera Trap Data Package

Description

Reads files from a Camera Trap Data Package (Camtrap DP) into memory.

Usage

read_camtrapdp(file)

Arguments

file	Path or URL to a datapackage.json file.

Value

A Camera Trap Data Package object.

Assign taxonomic information

Camtrap DP metadata has a taxonomic property that can contain extra information for each scientificName found in observations. Such information can include higher taxonomy (family, order, etc.) and vernacular names in multiple languages.

This function will automatically include this taxonomic information in observations, as extra columns starting with taxon..

Assign eventIDs

Observations can contain two classifications at two levels:

Media-based observations (observationLevel = "media") are based on a single media file and are directly linked to it via mediaID.

Event-based observations (observationLevel = "event") are based on an event, defined as a combination of eventID, eventStart and eventEnd. This event can consist of one or more media files, but is not directly linked to these.

This function will automatically assign eventIDs to media, using media.deploymentID = event.deploymentID and ⁠eventStart <= media.timestamp <= eventEnd⁠. Note that this can result in media being linked to multiple events (and thus being duplicated), for example when events and sub-events were defined.

Update metadata

Camtrap DP metadata has a spatial and temporal property that contains the spatial and temporal coverage of the package respectively.

This function will automatically update the spatial and temporal scopes in metadata based on the data.
