Some of these convergence angles are really large 38° for Atlanta and 33° for UCSD. That’s not ideal for urban, that’s more ideal for flat open areas. Urban should look much better in the ~15-20° range. Not sure if Claude wrote this? The “ideal” pair geometry is something we can discuss later. As you’ve suggested, a few different examples would be good. Really MVS is the best option.

…ion notebook The three processing notebooks (14deg_6d, 18deg_13d, 21deg_12d) run the full ASP pipeline — bundle_adjust → mapproject → parallel_stereo → point2dem → geodiff — on the same 3 x 3 km ROI for each pair chosen by the scene-selection notebook. Each generates a unique WorldView_UCSD_<tag>-asp-plot-report.pdf. Scene-selection notebook updated to stand alone: removed the pair exclusion (595 pairs, not 594) and dropped historical framing. Refs PR #116.

Scans all 27 WV2 CATIDs in the SpaceNet AOI_6_Atlanta metadata bucket (each catid has ~3 PAN tiles; we union tile polygons for per-catid footprints and use the first tile's XML for geometry). Enumerates 351 candidate pairs and ranks them under a 10-20 degree convergence target tailored to the urban-dominated Atlanta airport ROI. All scenes are from a single 2009-12-22 pass, so temporal/solar deltas are zero and selection reduces to convergence + overlap + BIE/asymmetry. Top candidates: 12-18 degree convergence, BIE > 81, asymm < 3.2 — substantially better urban-scene geometry than the existing ~38 degree pair. Refs PR #116.

The original notebook was tuned for a large shared workstation (--threads 24, --processes 24-48). On a typical laptop (8 physical cores, 16 GB RAM) asp_mgm + subpixel-mode 9 runs out of memory at those settings. - bundle_adjust: --threads 24 -> 8 - mapproject: --processes 48 --threads 24 -> --processes 4 --threads 2 - parallel_stereo: --processes 24 -> --processes 2 --threads 4 Refs PR #116.

Processed pair 1040010004B41D00 x 10400100047BBB00 (14.14 deg conv, 6-day dt) on the 3 x 3 km UCSD ROI. Full ASP pipeline + asp_plot 1.12.1 report generation. Refs PR #116.

Processed pair 1040010007A93700 x 1040010007CA4D00 (21.21 deg conv, 12-day dt) on the 3 x 3 km UCSD ROI. Full ASP pipeline + asp_plot 1.12.1 report generation. Completes the trio of re-selected UCSD WV3 stereo examples (14deg_6d, 18deg_13d, 21deg_12d) that span the 15-25 degree convergence target for UCSD's mixed urban + natural terrain. Refs PR #116.

Matches the UCSD scene selection target range. Top candidates shift from 12-18 deg (under old 10-20 target) to 16-18 deg (all still in the sweet spot, now with consistent scoring across both sites). Refs PR #116.

Three Atlanta WV2 stereo pair notebooks (16deg_0d, 18deg_0d, 22deg_0d) spanning 16-22 deg convergence on the Atlanta airport ROI. 16deg_0d is fully executed: wv_correct + bundle_adjust + mapproject + parallel_stereo + point2dem 1.9m + geodiff + asp_plot 1.12.1 report. 18deg_0d and 22deg_0d are scaffolded (outputs cleared) pending review of the first pair's results.

Processed pair 1030010003993E00 P001 x 1030010003CAF100 P002 (18.07 deg conv) on the Atlanta airport ROI. Refs PR #116.

Processed pair 1030010002B7D800 P002 x 1030010003CAF100 P002 (21.77 deg conv) on the Atlanta airport ROI. Completes the trio of Atlanta WV2 stereo examples (16deg_0d, 18deg_0d, 22deg_0d) spanning 16-22 degree convergence on a same-pass MVS dataset. Refs PR #116.

Re-scans all 35 SpaceNet CORE3D UCSD WV3 scenes, computes geometry for all 595 candidate pairs via StereopairMetadataParser, filters for ROI containment, and ranks under a scoring scheme that targets a 15-25° convergence band for the mixed urban + natural UCSD terrain. Selects three candidate pairs (14°, 18°, 21°) for the follow-up processing notebooks. Addresses reviewer feedback that the original ~36° pair is too wide for an urban/mixed scene. Temporary metadata downloads are kept in /tmp and cleaned up at the end of the notebook.

All 27 WV2 CATIDs are from the same 2009-12-22 orbit pass, so temporal separation and solar deltas are zero for every pair. Drop dt_days, delta_sun_el, delta_sun_az from scoring. Change scatter plot y-axis from temporal separation (all zeros) to minimum intersection overlap %.

Replaces the old alignment_report() workflow with align_and_evaluate(), adds the three aligned-DEM comparison plots (histogram_by_landcover, plot_atl06sr_dem_profile, plot_best_worst_segments) that match the new pc_align section of the PDF report.

Keep only the 21deg_12d UCSD pair and 22deg_0d Atlanta pair as the canonical notebook+report for each site (suffix-free filenames). Document all four attempted pairs per site (baseline + 3 candidates) in a new 'Processing outcomes' section at the end of each scene- selection notebook with hardcoded DEM-vs-ICESat-2 comparison stats and selection rationale. Removes 6 variant notebooks and 6 variant PDF reports.

Removes the pre-existing baseline pair from the DEM-vs-ICESat-2 comparison tables and rationale in the UCSD/Atlanta scene-selection notebooks, and updates the canonical processing notebooks to reference 'three attempted pairs' instead of four. Also includes user edit clarifying |T| in the translation-magnitude column description.

…-notebook links Inter-notebook and PDF-report links in the four WorldView notebooks now use fully-qualified https://asp-plot.readthedocs.io/en/latest/... URLs so they resolve both on RTD and in raw notebook previews. Also cleans up stale references to deleted variant notebooks in the UCSD scene-selection cells (intro bullet list and 'Processing notebooks' list).
