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