Sample camera trap station information
Description
Example camera trap station information table
Usage
data(camtraps)
Format
A data frame with 3 rows and 7 variables
Details
This is a general example of how information about camera trap stations are arranged in camtrapR. It contains setup and retrieval dates and coordinates. If more than 1 camera was set up at a station (e.g. 2 cameras facing each other), a camera ID column must be added, with camera-specific information instead of station-specific information. If cameras malfunctioned repeatedly, additional pairs of problem columns can be added, e.g. "Problem2_from" and "Problem2_to" etc..
The variables are as follows:
Station | Camera trap station ID |
utm_y | y coordinate of station (northing) |
utm_x | x coordinate of station (easting) |
Setup_date | camera trap setup date |
Retrieval_date | camera trap retrieval date |
Problem1_from | first day of camera malfunction |
Problem1_to | last day of camera malfunction |
Note
The coordinates can be in the units of any coordinate system. UTM was chosen as an example, but it could be latlong or anything else, too. capthist objects (as created by spatialDetectionHistory for spatial capture-recapture analyses) expect the unit to be meters.
