Description: Builds potentiometric surface products from groundwater monitoring
    data. The package prepares groundwater observations from direct water-level
    measurements or depth-to-water data paired with land-surface elevations,
    interpolates thin-plate spline surfaces by default, supports alternative
    and user-supplied interpolation methods, exports raster and contour
    products, and derives hydraulic-gradient flow arrows. Raster operations use
    methods from Hijmans (2025) <doi:10.32614/CRAN.package.terra>, thin-plate
    spline interpolation uses methods from Nychka et al. (2021)
    <doi:10.5065/D6W957CT>, and geostatistical interpolation uses methods from
    Pebesma (2004) <doi:10.1016/j.cageo.2004.03.012>.
