Geospatial data from a global survey of martian fan-shaped sedimentary landforms

Abstract

Data in this article are related to the research article “The global distribution and morphologic characteristics of fan-shaped sedimentary landforms on Mars”. We used globally available image and topographic data to document the location of every fan-shaped sedimentary landform on the surface of Mars. 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.
