Nouragues plot 201 coordinates

Source: R/data_documentation.R
NouraguesPlot201.Rd

Simulated corner coordinates of Nouragues 'Petit plateau' plot 201. The original coordinates have been modified to make the plot non-squared, and 10 repeated measurements of each corner have been simulated adding a random error to x and y coordinates.

Usage

data(NouraguesPlot201)

Format

A data frame with 40 (simulated GPS measurements) of the 8 following variables :

  • Site: Name of the site set up in the Nouragues forest

  • Plot: Plot ID of the site

  • Xfield: Corner location on the x-axis in the local coordinate system (defined by the 4 corners of the plot)

  • Yfield: Corner location on the y-axis in the local coordinate system

  • Xutm: Corner location on the x-axis in the UTM coordinate system

  • Yutm: Corner location on the y-axis in the UTM coordinate system

  • Long: Corner longitude coordinate

  • Lat: Corner latitude coordinate
