IMOSdata: Example detection dataset sourced from IMOS ATF

IMOSdataR Documentation

Example detection dataset sourced from IMOS ATF

Description

This dataset contains an example dataset containing 11 tagged Tiger sharks tracked at Heron and One Tree Island, Australia, extracted from the Integrated Marine Oberving System's Animal Tracking Facility (IMOS ATF). The data is in the default format used by the IMOS ATF containing the relocations of coded tags across an array of acoustic hydrophones. The data also contains metadata associated with tag and receiver deployments.

DetectionDistribution_QC

a numeric vector containing QC flag. Detection occurred within expert distribution area? (1:yes, 2:no, 3:test not performed). Not required for the functioning of the ATT operations.

DistanceRelease_QC

a numeric vector containing QC flag. Detection occurred within 500 km of release location? (1:yes, 2:no). Not required for the functioning of the ATT operations.

ReleaseDate_QC

a numeric vector containing QC flag. Detection occurred before the tag release date? (1:yes, 2:no). Not required for the functioning of the ATT operations.

ReleaseLocation_QC
