Fluvial Systems (2018, updated Valley Networks)

External link.

“This dataset represents an update of previous global maps of Martian fluvial systems. We included all the valleys longer than 20 km.”

Each polyline is classified into these categories: Long valley, Single valley, Valley network. The db also contains age.

This db is based on the Hynek et al (2010) database and contains additions, removals and course corrections.

This dataset is hosted at this location:

This figure shows the additions to the previous valley network database (Hynek et al. 2010) in a sample region. Blue lines represent valley networks mapped by Hynek et al. 2010 and red lines represent additions by Alemanno et al. 2018.
