shapefile_interpolate

This function interpolates values at specified points using x, y coordinates and a target variable
from a shapefile. It supports "Kriging" and "Tps" interpolation methods.

Tools for both single and batch image manipulation and
analysis (Olivoto, 2022 <doi:10.1111/2041-210X.13803>) and
phytopathometry (Olivoto et al., 2022 <doi:10.1007/S40858-021-00487-5>).
The tools can be used for the quantification of leaf area, object
counting, extraction of image indexes, shape measurement, object
landmark identification, and Elliptical Fourier Analysis of object
outlines (Claude (2008) <doi:10.1007/978-0-387-77789-4>). The package
also provides a comprehensive pipeline for generating shapefiles with
complex layouts and supports high-throughput phenotyping of RGB,
multispectral, and hyperspectral orthomosaics. This functionality
facilitates field phenotyping using UAV- or satellite-based imagery.

shapefile_interpolate function

<dl><dt>shapefile</dt>
<dd>An sf object containing the x, y, and target variable (z)
columns. It is highly recommended to use <code>shapefile_measures()</code> to obtain
this data.</dd>
<dt>z</dt>
<dd>A string specifying the name of the column in the shapefile that
contains the target variable to be interpolated.</dd>
<dt>x</dt>
<dd>A string specifying the name of the column containing x-coordinates.
Default is 'x'.</dd>
<dt>y</dt>
<dd>A string specifying the name of the column containing y-coordinates.
Default is 'y'.</dd>
