Terrain Metrics
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.
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.

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-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 are shown with the source isobaths in black. The black lines mark the depth horizons that were buffered to create extraction corridors.
PCA scores retain site metadata and the axis labels report dominant loading directions. This makes exploratory terrain separation easier to inspect before formal modeling.
