[OSD] Missing drainage classes in derived site-level columns
brownag opened this issue · 1 comments
At least 47 series currently return blank/NA for the derived drainage site-level column. I consider to be an error in general. 39 of these have some sort of drainage class referenced in the overview. some might have the information necessary to parse and convert to standard classes, whereas others do not.
One type unhandled phrasing (that was already known to "not work") is in reference to natural vs. altered drainage. The current parsing does not work for "poor to very poor" due to lack of "ly" at the end of class names. I have seen several series in CA with this issue.
For example for the SACRAMENTO series:
DRAINAGE AND PERMEABILITY: Natural drainage is poor to very poor. Altered drainage occurs in reclamation districts and areas protected by levees, thus improving the drainage. The water table fluctuates between a depth of 0 inches to below 60 inches (152 cm). Surface runoff is very slow to slow. Permeability is slow. Subject to frequent overflow where not protected by levees or located within flood control systems.
Other cases, for example MELLOE soil series, the drainage and permeability section does not reference a drainage class. No amount of parsing corrections will be able to fix these; it appears these are following the newer style of having a tabular overview section.
The following OSDs have NA drainage
Imperfectly drained is a synonym of somewhat poorly drained per SSM (1951)
