Phase progress
✓ Phase 1 — extract 165-page PDF into structured records 42 streams · 8/8 anchors ⚠ Phase 2 — geocode against NHD flowlines × Kent roads 26/62 sites · gate: 80% ○ Phase 3 — GPX/KML export for Gaia + CalTopo pending ○ Phase 4 — MapLibre web map with offline tiles pending
Phase 2 hit 42% instead of the 80% target because NHDPlus HR doesn't name several of the coldest streams (Butternut, Coopers, Duke, Shaw, Spring, Rum, Stegman). Next: try OSM waterways as a supplementary source, or ship Phase 3 on the partial data.
