HogDeer
Description
Example camera trapping data set containing camera encounters of hog deer
(Axis porcinus).
Usage
HogDeer
Format
A list consisting of 3 elements
- sites
A data.frame containing information for each camera, including
the first day (sday) and last day (eday) of operation for each camera
- encounters
A data.frame containing columns day giving the day
of encounter, distance, giving the distance bin numbers. Distance bins are
numbered with 1 indicating an image in the 1st bin (i.e. 0 - 2.5 m) and 5
indicating an image in the 5th bin (i.e. 10 - 12.5m). These are converted to distances
(i.e. distance to the midpoint of each bin in meters) automatically by eFrameDS.
Group size of the encounter is given in count and cam gives the camera ID.
stay gives the estimate of residence time (staying time in seconds) and
censor is an variable indicating a fully observed (censor = 1) or right
censored (censor = 0) staying time.
- cutpoints
A vector of the distance categories (bins) used.
Details
The dataset consists of distance sampling data from camera traps as well as data
on residence times in front of the camera (staying time) for each encounter.
Distance sampling data is used for estimating the effective sampling area of the
camera viewshed using dist_func. The effective camera viewshed area and staying
time data are required for use in the REST model. Distance bin numbers for
images of hog deer were derived from markers placed in the camera viewshed at
2.5, 5.0, 7.5 and 10 m from the camera. The right truncation distance was set at 12.5 m.
