| ## Complete development-snapshot registry |
| |
| This registry classifies the **10,831 physical files** in the complete internal |
| development snapshot. That inventory includes files named directly by the |
| canonical records, files reached through a declared sample-directory handle, |
| optional context, evaluator-only hidden/reference files, support exports, and |
| GDAL `.aux.xml` sidecars. The public thin release contains **9,328** source |
| files. Running the pinned Sen1Floods11 hydrator adds exactly 300 execution files |
| (100 `S1Hand.tif`, 100 `JRCWaterHand.tif`, and 100 generated |
| `S1Portable.tif` files), producing a **9,628-file hydrated execution release**. |
| The remaining internal Sen1Floods11 labels, cached derivatives, and hidden |
| evaluation products in this table are not public agent inputs. |
| |
| “Required” and “optional” below refer to unique canonical path declarations; |
| “support/internal” means a development-snapshot file is not directly named as |
| an initial path. Directory-resolving worker reads are tracked by the |
| opened-handle exact-path authorization audit. |

| The reproducible check is `release_tools/audit_c01_source_registry.py`. It is |
| check-only unless `--output` is supplied. `--mode thin` validates the public |
| archive before hydration; `--mode hydrated` requires the complete pinned |
| execution subset. The retained development-snapshot evidence is |
| `release_tools/evidence/source_asset_registry_development_snapshot.json`; it |
| reports zero unclassified physical files, zero unclassified referenced paths, |
| zero missing required paths, zero outside-repository paths, zero |
| `exists`-flag mismatches, and zero uncited direct raster-sidecar source labels |
| for the complete 10,831-file internal snapshot. |

| data, including `source_assets/multi_hazard/*/*/osm/pois.geojson` and the |
| OSM-derived properties in `source_assets/routing/*/derived/*`. Terms and |
| required notice: |

| Use “© OpenStreetMap contributors” and disclose ODbL; assess whether a |
| released derived database triggers share-alike obligations. **Status: |
| conditional (ODbL 1.0).** |
| |
| 22. **Copernicus Emergency Management Service On-Demand Mapping.** Supplies |
| `source_assets/routing/*/copernicus/flood_extent.geojson`. Each routing |
| sample records its `activation_code`, `product_type`, `product_id`, and |
| `product_key` in `input/metadata.json`. CEMS permits reproduction, |
| distribution, public communication, adaptation, and combination subject |
| to its terms and citation guidelines: |

| **Status: conditional; CEMS source citation required and restricted |
| products must be excluded.** |
| |
| 23. **OpenAQ v3.** Construction queried OpenAQ, but all accepted air-pollution |
| AOIs contain zero target-window measurements: `openaq_stations.csv` is |
| header-only and `openaq_status.json` records |
| `completed_no_window_measurements`. OpenAQ contributes provenance of the |
| empty query only, not analytical evidence or answer values. Official terms: |
| [OpenAQ terms of use](https://docs.openaq.org/about/terms). **Status: no |
| measurement payload bundled; do not cite OpenAQ as answer evidence.** |
| |
| ### Parent benchmark datasets |
|
|
| 24. **Sen1Floods11 v1.1.** The 100 packaged flood samples retain S1, optional |
| S2/JRC views, and hand/cached labels from the structure documented by the |
| original project. The required dataset citation is Bonafilia, D., Tellman, |
| B., Anderson, T., and Issenberg, E. (2020), “Sen1Floods11: A Georeferenced |
| Dataset to Train and Test Deep Learning Flood Algorithms for Sentinel-1,” |
| *IEEE/CVF CVPR Workshops*, pp. 210–211. Use the |
| [official Cloud to Street GitHub repository and data-access instructions](https://github.com/cloudtostreet/Sen1Floods11) |
| together with the |
| [official CVPR paper](https://openaccess.thecvf.com/content_CVPRW_2020/html/w11/Bonafilia_Sen1Floods11_A_Georeferenced_Dataset_to_Train_and_Test_Deep_Learning_CVPRW_2020_paper.html). |
| The upstream repository provides a public bucket and citation but does not |
| declare an explicit dataset `LICENSE` file. The Apache-2.0 license in the |
| separate EOEPCA mirror is not treated as authority for Cloud to Street’s |
| original data. The public package therefore excludes the Sen1Floods11 |
| payload and supplies the checksum-pinned upstream hydrator described |
| below. Redistributing those files instead requires written permission or |
| an authoritative dataset license. |
| |
| 25. **xBD / xView2.** All `source_assets/xbd_damage/*` pre/post images and |
| damage polygons originate from xBD. Their intermediate preparation was |
| performed within this project by a coauthor and is not an external data |
| source, so that internal package is intentionally not cited. Cite Gupta et |
| al. (2019), DOI |
| [10.48550/arXiv.1911.09296](https://doi.org/10.48550/arXiv.1911.09296), the |
| [official xBD dataset page](https://xview2.org/dataset), and the |
| [CMU Software Engineering Institute xView2 project](https://www.sei.cmu.edu/projects/xview-2-challenge/). |
| CMU/SEI states that xBD is available for public use under a Creative |
| Commons license; its official |
| [xView2 imagery credit](https://insights.sei.cmu.edu/annual-reviews/2020-year-in-review/wildfire-response-tests-xview2-damage-assessment-prototype/) |
| identifies the raw imagery as CC BY-NC 4.0. Preserve attribution and |
| non-commercial restrictions for xBD imagery and derivatives, and do not |
| represent them as CC-BY-4.0. |
| **Status: conditional and documented; no undeclared third-party mirror is |
| part of the provenance chain.** |

| ## Sen1Floods11 download and local placement |
|
|
| The development workspace retains its Sen1Floods11 files for the reproducible |
| 2,921-record replay. The public distribution contract is a thin package: it |
| excludes the packaged `source_assets/sen1_flood/` payload, and users hydrate |
| the selected inputs directly from the official Cloud to Street bucket. |
|
|
| Official references: |
|
|
| - Repository, citation, and access instructions: |
| [cloudtostreet/Sen1Floods11](https://github.com/cloudtostreet/Sen1Floods11) |
| - Official bucket root: `gs://sen1floods11/v1.1/` |
| - Upstream S1 folder: |
| `gs://sen1floods11/v1.1/data/flood_events/HandLabeled/S1Hand/` |
| - Upstream JRC folder: |
| `gs://sen1floods11/v1.1/data/flood_events/HandLabeled/JRCWaterHand/` |
|
|
| Only 100 selected chips are used. The installer downloads 200 official |
| GeoTIFFs: one `S1Hand` raster for each chip, plus one `JRCWaterHand` raster for |
| the D/E known-water comparison tasks. It then generates the 100 portable S1 |
| runtime derivatives. The resulting layout is: |
|
|
| ```text |
| source_assets/sen1_flood/<chip_id>/labels/S1Hand.tif |
| source_assets/sen1_flood/<chip_id>/labels/JRCWaterHand.tif |
| source_assets/sen1_flood/<chip_id>/derived/S1Portable.tif |
| ``` |
|
|
| The upstream filenames include the chip ID, whereas the benchmark-local names |
| do not. For example: |
|
|
| ```text |
| gs://sen1floods11/v1.1/data/flood_events/HandLabeled/S1Hand/Bolivia_103757_S1Hand.tif |
| -> source_assets/sen1_flood/Bolivia_103757/labels/S1Hand.tif |
| |
| gs://sen1floods11/v1.1/data/flood_events/HandLabeled/JRCWaterHand/Bolivia_103757_JRCWaterHand.tif |
| -> source_assets/sen1_flood/Bolivia_103757/labels/JRCWaterHand.tif |
| ``` |
|
|
| From the repository root, the supported installer hydrates exactly the pinned |
| 100-chip subset over the official bucket's public HTTPS endpoint. It downloads |
| atomically and accepts a file only when both its byte size and SHA-256 match |
| the pinned manifest: |
|
|
| ```bash |
| # Inspect the plan without writing files. |
| python3 release_tools/fetch_sen1floods11_subset.py --dry-run |
| |
| # Download missing files, retaining already verified files. |
| python3 release_tools/fetch_sen1floods11_subset.py |
| |
| # Verify an existing installation without network access. |
| python3 release_tools/fetch_sen1floods11_subset.py --verify-only |
| ``` |
|
|
| The installer is `release_tools/fetch_sen1floods11_subset.py`; its immutable |
| selection, official source URLs, local destinations, sizes, and checksums are |
| in `release_tools/manifests/sen1floods11_required_100.json`. It refuses to |
| overwrite a mismatched existing file unless the user explicitly supplies |
| `--replace-mismatched`. After verifying an official S1 file, it creates or |
| validates `S1Portable.tif` by replacing only non-finite/declared-nodata pixels |
| with `-9999.0`; valid values and georeferencing are unchanged. The manifest is |
| bound to canonical dataset SHA-256 |
| `03988b960e6b09ae01fb622fe45b35d763eb705485cddc3cea68bcac7ae63fe1`, so a |
| changed canonical file requires an explicit manifest update rather than silently changing the |
| download selection. |
|
|
| For transparency, this is the equivalent unpinned `gsutil` procedure. The |
| manifest-backed installer above is preferred because this loop does not check |
| integrity: |
|
|
| ```bash |
| for chip_id in $(python3 -c 'import json; print(" ".join(sorted({r["sample_id"] for r in map(json.loads, open("data/core/geodisaster_2921_source_with_splits.jsonl")) if r["id"].startswith("sen1_flood/")})))'); do |
| mkdir -p "source_assets/sen1_flood/${chip_id}/labels" |
| gsutil cp \ |
| "gs://sen1floods11/v1.1/data/flood_events/HandLabeled/S1Hand/${chip_id}_S1Hand.tif" \ |
| "source_assets/sen1_flood/${chip_id}/labels/S1Hand.tif" |
| gsutil cp \ |
| "gs://sen1floods11/v1.1/data/flood_events/HandLabeled/JRCWaterHand/${chip_id}_JRCWaterHand.tif" \ |
| "source_assets/sen1_flood/${chip_id}/labels/JRCWaterHand.tif" |
| done |
| ``` |
|
|
| The current benchmark does **not** require users to download `LabelHand`, |
| `S1OtsuLabelHand`, hidden reference products, prepared overlays, or Sentinel-2 |
| chips. `LabelHand`, cached Otsu labels, and `hidden/*` are forbidden answer |
| inputs. Cached Otsu files are explicitly excluded by |
| `release_tools/manifests/c10_excluded_legacy_rasters.json`. Public S1/JRC |
| previews may be generated locally but are not analytical inputs. The official |
| selected S1+JRC download is approximately 157 MiB; generated portable S1 files |
| add approximately 145 MiB locally. |
|
|
| The public-release builder enforces this contract: |
|
|
| 1. All 1,503 development files below `source_assets/sen1_flood/` are excluded |
| from the published archive; the complete development snapshot is preserved. |
| 2. The installer and pinned 100-chip checksum manifest are bound to the |
| canonical dataset SHA-256. |
| 3. `JRCWaterHand` is a required declared input for D/E; A/B/C do not receive |
| that handle. |
| 4. Optional previews not regenerated by the installer are not required agent |
| inputs. |
| 5. A hydrated release must pass the source-registry/path audit and complete |
| 500-question Sen1 replay before upload. |
|
|
| ## Project-derived and software-only items |
|
|
| - Raster indices, threshold masks, panels, grids, polygons, route scores, |
| reports, and overlays are transformations or combinations of the applicable |
| inputs above. Their provenance is inherited; project authorship does not |
| erase upstream conditions. |
| - The source contracts use `nifc_perimeter__event`, `radd_alerts__event`, |
| `viirs_lst__target`, `cams_no2__peak`, and `viirs_active_fire__event` |
| sidecars identify the exact products, bands, physical units, native |
| resolutions, transformations, and checksums. Air-pollution classes are |
| benchmark-relative column/intensity states, not WHO or health categories. |
| - OSMnx is software used to create routing products, not a data source. Cite |
| Boeing (2025), DOI [10.1111/gean.70009](https://doi.org/10.1111/gean.70009); |
| OSMnx itself is MIT licensed. See the |
| [official documentation](https://osmnx.readthedocs.io/en/stable/). |
| - Google Earth Engine is the processing/access platform for many cached |
| products. Its use does not replace any product-specific citation or terms. |
| - The project-authored JSONL records, questions, schemas, and chains may be |
| CC-BY-4.0, but a mixed-source archive containing `source_assets/` must use a |
| mixed/custom license declaration and ship this registry. |
|
|
| ## Release licensing requirements |
|
|
| xBD provenance is attributed to the original xBD/xView2 sources, while the |
| coauthor-managed preparation is treated as an internal project transformation. |
| The public package uses the Sen1Floods11 thin-release procedure above unless |
| an explicit redistribution license is obtained. Every release must also |
| retain the required upstream notices and apply the ODbL requirements to any |
| released routing or POI databases. |
