# 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. ## Family-to-source map | Packaged family | Direct upstream data | Project-derived/support data | |---|---|---| | `deforestation` | Sentinel-2 SR Harmonized; Sentinel-1 GRD; Hansen GFC v1.13 | RGB previews, annual loss masks, and quality reports derived from those products | | `multi_hazard/wildfire` | MCD64A1.061; VNP14A1.002; NIFC WFIGS incident perimeters; Sentinel-2 SR Harmonized; Landsat 8/9 C2 L2; WorldPop; OSM | dNBR and Landsat dNBR; `nifc_perimeter__event` is the clipped/rasterized authoritative incident geometry | | `multi_hazard/deforestation` | Hansen GFC v1.13; JRC TMF v1_2023 AnnualChanges; WUR/GFW RADD v1; Sentinel-2 SR Harmonized; WorldPop; OSM | NDVI change; 2022 TMF annual loss; `radd_alerts__event` decodes official `date_conf` alerts inside the declared event window | | `multi_hazard/urban_expansion` | Dynamic World V1; GHSL P2023A GHS_BUILT_S; ESA WorldCover v100/v200; Sentinel-2 SR Harmonized; WorldPop; OSM | NDBI change and source-native built-gain masks | | `multi_hazard/drought` | CHIRPS Daily; ERA5-Land Daily Aggregated; MOD13Q1.061; VNP21A1D.002; WorldPop; OSM | SPI/NDVI anomalies and drought masks; VNP21 LST is optional context and two QA-empty AOIs are explicitly omitted | | `multi_hazard/air_pollution` | Sentinel-5P OFFL L3 NO2/SO2/CO; MCD19A2.061; CAMS NRT total-column NO2; WorldPop; OSM | Train-only S5P quartile footprint and per-source regional-intensity normalization; no WHO or surface-health claim | | `routing` | Sentinel-2 L2A; CEMS On-Demand Mapping flood products; OpenStreetMap | OSMnx-derived road graphs, candidate routes, scores, selected routes, and rendered overlays | | `sen1_flood` | Sen1Floods11 packaging of Sentinel-1, Sentinel-2, JRC Global Surface Water, and hand labels | Public previews/packaged overlays; LabelHand-derived hidden reference files excluded from agent inputs; current S1-only Otsu runtime outputs | | `xbd_damage` | xBD/xView2 imagery and damage labels supplied through the project’s coauthor-managed preparation | Coordinate conversions, grids/quadrants, masks, questions, and deterministic summaries | ## 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. | Key | Packaged path family | Physical files | Canonical role | Registered origin | |---|---|---:|---|---| | D01 | `deforestation/*/cache/s1_grd/*.tif[.aux.xml]` | 245 | 240 required | Sentinel-1 GRD; entry 1 below.

The builder masks mandatory-QA, data-quality, and cloud bits uniformly and uses a 32-day median with nearest-neighbor export. Two AOIs have no QA-valid pixel and therefore omit the optional handle rather than using a proxy. Official product and terms: [Earth Engine catalog](https://developers.google.com/earth-engine/datasets/catalog/NASA_VIIRS_002_VNP21A1D). **Status: verified; cite NASA LP DAAC.** 15. **MODIS MAIAC MCD19A2.061 AOD — `MODIS/061/MCD19A2_GRANULES`.** Supplies `modis_aod__peak`.

Terms and required notice: [OpenStreetMap copyright and licence](https://www.openstreetmap.org/copyright). 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: [CEMS terms and conditions](https://mapping.emergency.copernicus.eu/terms-and-conditions/). **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.

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//labels/S1Hand.tif source_assets/sen1_flood//labels/JRCWaterHand.tif source_assets/sen1_flood//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.

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.
