Seascape Toolkit

The shape, composition, and connectivity of the marine environment.

Documentation site · Variables · Methods · Examples

Seascape Toolkit turns reviewed geospatial sources into reproducible physical and structural marine features. It supports bathymetry and terrain, modeled substrate, shoreline and waterbody geometry, freshwater connections, mapped vegetation and reef evidence, built coastal features, and the H3 water support that relates them. It is an independently installable Python package; no OrcaCast checkout is required.

The toolkit is for researchers, GIS users, and downstream applications that need analysis-ready features with source lineage, spatial support, and explicit missingness. Physical conditions and mapped evidence do not establish species occurrence or habitat suitability. Regional source data and an audited regional release are not bundled.

v0.1.0 status and compatibility

v0.1.0 is a public preview, not a stable 1.0 contract. It supports Python 3.14 on the Linux x86_64 and macOS ARM64 environments exercised by CI. Other operating systems are not currently claimed. During 0.x, documented minor releases may change APIs, CLI behavior, schemas, variables, or scientific methods; patch releases preserve intended public and scientific contracts.

The toolkit records source lineage, configuration, checksums, spatial support, missingness, and versioned scientific interpretations so results can be reproduced and compared. Those records do not remove source-specific limitations: regional coverage, rights, horizontal CRS, vertical datum, resolution, and accuracy must be reviewed for each data release. The synthetic demo does not validate regional accuracy, species habitat, navigation safety, or predictive fitness.

Software, scientific interpretation, and materialized data have deliberately separate identities. See the release process and changelog for the identity model, Semantic Versioning policy, method changes, and immutable-release rules. Rebuilding data does not by itself create a Python package version, Git tag, or GitHub Release.

Install and get a first result

Use a Python 3.14 source checkout with pyproject.toml at its root. Clone the repository, then run these commands from the checkout. Installation retrieves declared Python dependencies; the demo itself does not need source downloads or credentials.

SEASCAPE_ENV="$PWD/.venv"
python3.14 -m venv "$SEASCAPE_ENV"
. "$SEASCAPE_ENV/bin/activate"
python -m pip install 'pip>=26.2'
python -m pip install .
python -m pip check

Leave the checkout and select a fresh owned workspace:

cd "$(mktemp -d "${TMPDIR:-/tmp}/seascape-first-result.XXXXXX")"
export SEASCAPE_WORKSPACE="$PWD/seascape-workspace"
seascape --workspace "$SEASCAPE_WORKSPACE" demo

The CLI prints Synthetic software acceptance: PASS (not a regional release) after validating the production bathymetry transform on synthetic inputs. It reports paths to Parquet, manifest, JSON report, and figures under $SEASCAPE_WORKSPACE/.seascape/demo/. Missing depth stays null; this is a software check, not a regional accuracy claim. See the full quick start and demo guide.
