--- title: "Visual proof" output: rmarkdown::html_vignette vignette: > %\VignetteIndexEntry{Visual proof} %\VignetteEngine{knitr::rmarkdown} %\VignetteEncoding{UTF-8} --- ```{r, include = FALSE} knitr::opts_chunk$set(collapse = TRUE, comment = "#>") ``` The visual proof is a compact gallery from the package QA run. It shows that the site examples are built from real reduced bathymetry, that hillshade-supported maps render with vector overlays, and that profile and modeling outputs use the intended raster value columns. The full QA report is kept in `qa/visual-proof/visual-proof.md` in the source repository. The CRAN source package excludes the QA directory, so only selected small figures are copied into package figure assets for documentation. ## Terrain Metrics Slope over hillshaded bathymetry. *Slope over hillshaded Hole-in-the-Wall bathymetry. The figure demonstrates that metric maps can use bathymetry-derived hillshade and contours as visual context while preserving the metric as the mapped value.* ## Transects Terrain-oriented transects over hillshaded bathymetry. *Transects are oriented from local surface aspect and plotted over the prepared bathymetry. The line angle is recorded in the transect attributes so the choice is inspectable.* ## Cross-Sections Bathymetric cross-sections with bathy_m on the y-axis. *Cross-section profiles use `bathy_m` explicitly on the y-axis. Numeric metadata such as transect width, height, offset, and angle are ignored during automatic value-column inference.* ## Isobath Corridors Isobath corridors over hillshaded bathymetry with source isobaths in black. *Isobath corridors are shown with the source isobaths in black. The black lines mark the depth horizons that were buffered to create extraction corridors.* ## PCA Terrain PCA with site-colored points and loading labels. *PCA scores retain site metadata and the axis labels report dominant loading directions. This makes exploratory terrain separation easier to inspect before formal modeling.* ## Local QA Summary The local validation pass for this site recorded: - pkgdown build: completed locally - R CMD check: 0 errors, 0 warnings - source package size: below 9 MB - expected website URL: - deployment workflow: `.github/workflows/pkgdown.yaml` GitHub Actions results are available from the repository Actions tab: .
