For all volume metrics:
Cubic: CVTS, CVT, CV4, CV6, CV8,
Boardfoot: SV616, SV632, XINT6, SV816, XINT8

The appropriate place in the calculations to address non-merch may depend on which of these variables are used in biomass equations.

Address equations where floors were introduced to avoid zero values:

• 3
• 5
• 16
• 18
• 19
• 20
• 23
• 25

Consider using a cookiecutter template for a python package.

Perform cross-validation of ARB with FPS stand-level estimates.

FPS offers several stand-level metrics in STAND table that can be compared with ARB-calculated values for sanity check: CubicTot, CubicGrs, BoardGrs, several biomass components, CarbTree, CarbBole, CO2Tree, and CO2Bole.

Oregon and Washington have different equations used for east- vs. west-side. Need to have a polygon indicating the extent of these.

May be useful for pivot table work later on, identifies whether stand is available, various other designations...

• ensure zeroes returned for non-merch diameters
• ensure no negative values returned for any volume or biomass metric
• test_softwoods volume equations
• test_hardwoods volume equations
• test bark biomass
• test live branch biomass
• test total biomass

Great how-to guide here:
https://python-packaging.readthedocs.io/en/latest/

most softwood equations use the get_metric helper function while the hardwood equations directly request the metrics. Choose one or the other.

• Volume equations return non-negative values for all metrics on a range of tree sizes
• Biomass equations return non-negative values for all metrics on a range of tree sizes
  ...

Using dataframe in python, calculate all values needed:

• individual tree
• trees across stand (multiply by trees per acre)

Use an environment.yml and/or requirements.txt.

for trees removed due to GRP code (e.g., dead trees) or for which species weren't in crosswalk, add them back to the dataframe, but without any of the carbon calculations executed.

When editing species crosswalk table, entering a value for species number 299 (unknown conifer) and then running FPS2ARB.py triggered error because 299 was not represented in volume equations or something like that. Make sure all species that can be entered in crosswalk can work.

not all trees are live trees, indicated by GRP column in DBHCLS table in FPS database

Will be used to identify which volume equations need to be selected

Use the latest published version of equations:
http://www.arb.ca.gov/cc/capandtrade/protocols/usforest/2015/volume.equations.ca.or.wa.pdf

Add another column into outputs for AREA_RPT, which is for area net of roads and streams.

Use ARB equations to calculate BF volume for each tree.

• Read in property, stand, and tree records from FPS Access database into python dataframe
• Create table in FPS database to hold new data
• Write values to new table in FPS database
