Changelog

potentiomap 0.2.0

Observation preparation and quality checks

Validation and tuning

  • Added deterministic leave-one-out, random-fold, spatial-block, leave-cluster-out, user-fold, and independent validation through ps_validate().
  • Added design-specific method comparison, diagnostic plotting, exhaustive or reproducibly sampled candidate tuning, and optional nested validation.
  • Added empirical and directional variograms, independent candidate-model fitting, exploratory anisotropy, explicit variogram models, neighborhoods, anisotropy, trends, and raster or table covariates for kriging.

Support and uncertainty

  • Added compatible-surface ensembles and method-disagreement products.
  • Added retained kriging variance, conditional Gaussian simulation, supported TPS standard error, resampling sensitivity, and pointwise contour bands with explicit terminology and assumptions.
  • Prediction-support products retain training-hull, observation-distance, mask, and finite-prediction information, and modeled contours can be split by user-defined support criteria without calling those classes confidence.

Surface and event comparisons

  • Added aligned surface comparisons, paired-event head change, and numeric or raster vertical hydraulic gradients with explicit sign conventions.
  • Structured interpolation and contour results inventory diagnostics, conditions, requested methods or levels, and nonfinite outputs.

Monitoring-network analysis

  • Added conditional leave-one-well influence, reproducible network thinning, constrained sequential candidate ranking, and explicit parameter/grid sensitivity scenarios.

Profiles, cross-sections, and depth products

  • Added water-table or potentiometric depth surfaces, sampled surface profiles, and plot-ready cross-sections with well offsets and screen elevations.

GIS and reporting

  • Added validated open QML/SLD style export and offline HTML/DOCX technical reports from a package-owned template.
  • Hydraulic-gradient arrows retain endpoint support checks and the explicit endpoint_action = "none" legacy geometry option.

Documentation

  • Added small deterministic fixtures, expanded function examples, integrated vignettes, website articles, scientific due diligence, and release audits.
  • Rebuilt the hydrogeologist-facing README, package help, reference index, and Bootstrap 5 website configuration, with guidance for on-disk rasters and larger prediction grids.

Compatibility

  • Existing public functions remain exported, and ps_interpolate() continues to return a named list of SpatRaster objects by default.
  • Structured interpolation results now also retain exact template and method-fit objects needed by validation and model-conditional uncertainty.
  • ps_contours() still returns a SpatVector by default; structured interpolation and contour results remain opt-in.
  • Existing public names and valid positional calls remain available, requested interpolation methods are not silently replaced, and universal kriging keeps the documented uk_coordinate_scaling = "none" compatibility option.
