Summary

  • Add resampling explainer clarifying that bundled 10m DEM is actually 25m TRIM resampled
  • Add site-level 1m VCA comparing Robert Hatch / Richfield / Bulkley floodplain at native lidar vs 25m TRIM
  • Quantify "pop-ups": ~10% of 25m floodplain area is actually elevated barriers (roads, dykes, fill) visible only at 1m
  • Add anthropogenic barriers to floodplain connectivity interpretation section
  • Pre-build vignette for instant pkgdown rendering (no 20-min STAC fetch in CI)
  • Add resolution and restoration section to README
  • Bump to v0.1.1

Test plan

  • Verify pre-built vignette renders on pkgdown site
  • Confirm figures display correctly
  • Review pop-up area numbers against visual inspection

Closes #18
