Position of the plot on land surface (e.g., Summit, shoulder, upper slope, middle slope, lower slope, toeslope, no slope, channel bed, dune swale, pond).
Surficial deposits represent the parent material that are the geologic or organic precursors to the soil. They may either have been deposited by geologic (wind, ice, gravity or water) or biologic (organic) activity, or formed in place more-or-less directly from rocks and minerals below.

Code that uniquely references this record, allowing reference to this record for this version of this database. Better than a primary key, which is automatically generated by a database and not globally unique. VegBank Accession codes are only generated by VegBank, and therefore data integrity can be guaranteed, unlike with a primary key (number).
