d44 spatial grain confirmation #77

Closed ssnell6 closed 8 years ago

ssnell6 commented 8 years ago

d44 has mostly transient species, so there was discussion about redoing spatial grain to be less fine and encompass a more representative community.

3 grain identifiers: PSP_STUDYID: permanent study plot, mutually exclusive grouping of study forest stands (10 categories)

STANDID: study forest stand code (109 categories)

PLOTID: plot number WITHIN stand ID (239 categories)

Study areas are rectangular and measure either 1 or 0.4 ha, but there are also 0.1 ha circular plots along transects as well as randomly distributed. I believe these designations are tied to plot number, but there doesn't seem to be a designation of which size each row of the data set it is.

Current spatial grain is STANDID/PLOTNUMBER with 1500+ categories. I want to know if we should redo this and if we have to keep plotID, since that is the only grain measurement we have.

Nevermind this one will have to stay, it only works with plot number
