Aram Dorsum, Mars: decameter-scale polygon survey results

This is a shapefile containing the locations of polygonal fractures, ridges and other similar forms in the Aram Dorsum area of Mars. The shapefiles are classified into the following types:narrow (polygonal fractures with trough-like margins ~ 1 m wide)pos (polygonal fractures with ridge-like margins ~ 1 m wide)wide (somewhat discontinuous polygonal fractures with flat-floored, trough-like margins ~ 1-3 m wide)vein (criss-crossing positive relief forms with curvilinear to rectilinear patterns, ridges arer &lt; 1 m wide)tiny (meter-scale polygonal or mound like forms)<b></b><i></i><b></b><i></i><br>
