Source Provenance, Citations, and Upstream Terms

Verified against the packaged files and official provider pages on 2026-10-14. This document is the source registry for source_assets/; it is not legal advice and does not replace upstream terms.

License boundary

The GeoDisaster Project Contributors apply CC-BY-4.0 only to project-authored questions, answer schemas, tool chains, documentation, and annotations for which they hold the rights. That license does not relicense imagery, rasters, labels, OSM extracts, CEMS products, or derivatives of upstream data. Each upstream source below retains its own terms. Google Earth Engine is an access/processing platform, not the copyright source; cite the underlying product, not Earth Engine alone.

Status labels used below:

  • verified: an official provider page states reuse/redistribution terms.
  • conditional: reuse is allowed subject to attribution, share-alike, non-commercial, or product-specific conditions that the distributor must satisfy.

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.

Status: no measurement payload bundled; do not cite OpenAQ as answer evidence.

Parent benchmark datasets

  1. 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 together with the official CVPR paper. 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.

  2. 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, the official xBD dataset page, and the CMU Software Engineering Institute xView2 project. CMU/SEI states that xBD is available for public use under a Creative Commons license; its official xView2 imagery credit 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
  • 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:

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:

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:

# 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:

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; OSMnx itself is MIT licensed. See the official documentation.
  • 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.
