MOA-derived Structural Feature Map of the Ronne Ice Shelf This
data set provides a structural feature map of the Ronne Ice
Shelf in Antarctica (also known as the Filchner-Ronne Ice
Shelf). The map was developed as part of a project to study
fracture propagation in the Ronne Ice Shelf, with special focus
on the Evans Ice Stream. Features were digitized from the MODIS
Mosaic of Antartica (MOA), a composite of individual Moderate
Resolution Imaging Spectradiometer (MODIS) images taken between
20 November 2003 and 29 February 2004, with an effective
resolution of 125 m. The data set includes estimates of the
shelf boundary, including ice stream grounding zones, outlets of
glaciers feeding the shelf, extents of islands and ice rises,
and the location of the shelf front, and features observed
within the shelf, including suture zones between ice streams,
streaklines, fractures (crevasses and rifts), and fold-like
features. Individual features can be extracted as a group of
points and grouping is used to facilitate i
