Within geomorphology, geomorphometry applies morphometric analysis to the land surface as a continuous surface (general geomorphometry), and to objects such as landforms, elementary forms, channels, and drainage basins extracted from that surface (specific geomorphometry). Special attention is paid here to a comprehensive taxonomy of fundamental geomorphometric variables, both those related to fields and those characterizing objects. The former include field-specific and field-invariant as well as local and regional variables.
