We mapped fan outlines and associated drainage basins and collected a number of morphologic metrics. These data can be used as a boundary condition for studies of global scale studies of Mars, including climate and hydrologic modeling. Data files publicly available on Figshare include point shapefile of fan apices, and polygon shapefiles of fan outlines and drainage basins.", "claims": [{"id": "claim-method", "statement": "Fan long profile concavity B was found by fitting a negative exponential function to the equation", "kind": "methodological", "target": null, "evidence": [{"asset": "source:pmid:35990915", "locator": "sections[4] \"Experimental Design, Materials and Methods\" paragraph 6", "quote": "Fan long profile concavity B was found by fitting a negative exponential function to the equation"}], "state": "complete"}, {"id": "claim-data-access", "statement": "Geospatial data from a global survey of martian fan-shaped sedimentary landforms (Original data) (Figshare).", "kind": "methodological", "target": null, "evidence": [{"asset": "source:pmid:35990915", "locator": "sections[11] \"Data Availability\" paragraph 2", "quote": "Geospatial data from a global survey of martian fan-shaped sedimentary landforms (Original data) (Figshare)."}], "state": "complete"}, {"id": "claim-target-result", "statement": "The digitized fan-shaped landforms in these datasets describe the locations and morphologic properties of 1501 alluvial fans and scarp fronted deposits (SFDs; putative deltas) across the surface of Mars.", "kind": "qualitative", "target": null, "evidence": [{"asset": "source:pmid:35990915", "locator": "sections[3] \"Data Description\" paragraph 2", "quote": "The digitized fan-shaped landforms in these datasets describe the locations and morphologic properties of 1501 alluvial fans and scarp fronted deposits (SFDs; putative deltas) across the surface of Mars."}], "state": "complete"}], "gaps": []}, "experiment": {"state": "partial", "objective": "The digitized fan-shaped landforms in these datasets describe the locations and morphologic properties of 1501 alluvial fans and scarp fronted deposits (SFDs; putative deltas) across the surface of Mars.", "steps": [{"id": "read_published_estimate", "order": 1, "name": "Read the published estimate from the source", "kind": "other", "state": "complete", "blocked_on": null, "description": "The claim, method and evidence span published with the source article.", "duration_hours": null, "parameters": {}, "inputs": ["source:pmid:35990915"], "outputs": ["the published estimate and its evidence"], "instruments": [], "reagents": []}, {"id": "obtain_source_data", "order": 2, "name": "Obtain the source data from the named repository", "kind": "data-preparation", "state": "blocked", "blocked_on": "data:accession_absent", "description": "The GEO series accession resolves and its sample accessions are listed.
