FIESTA - Green-book Estimators
Green-Book (GB) module overview
FIESTA‘s Green-Book (GB) module calculates population
estimates and their sampling errors based on Bechtold and Patterson’s
(2005), ’Green-Book’ for FIA’s nationally-consistent, systematic annual
sample design, chapter 4 (Scott et al. 2005). FIA’s sample design is
based on 2 phases: the first phase uses remotely-sensed data to stratify
the land area to increase precision of estimates; while the 2nd phase
obtains photo and ground observations and measurements for a suite of
information across a hexagonal grid, each approximately 6000 acres in
size. The associated estimators and variance estimators are used for
area and tree attribute totals with the assumption of a simple random,
stratified design and double sampling for stratification. Adjustment
factors are calculated by estimation unit and strata to account for
nonsampled (nonresponse) conditions.
Functions include non-ratio estimators for area and tree estimates by
domain and ratio-of-means estimators for per-acre and per-tree estimates
within domain. In addition, FIESTA adjusts for nonsampled
conditions, supports post-stratification for reducing variance, and
reports by estimation unit or a summed combination of estimation units.
Output from the Green-Book module was tested and compared to output from
FIA’s publicly-available online tool (EVALIDator) for
state-level population estimates and associated sampling errors
generated from the FIA Database (FIADB).
Objective of tutorial
The Green-Book estimators can be used with FIA’s standard state-level population data (i.e, Evaluation) from the FIA database (FIADB) and also population data from a custom boundary. The population data includes a set of FIA plot data and summarized auxiliary information for post-stratification, including a table of area by estimation unit within the population, and a table of strata proportions by estimation unit. This tutorial steps through several examples using FIESTA’s Green Book module, for three different populations: (POP1) an FIA standard Evaluation, Wyoming 561301; (POP2) a custom boundary with one population, Bighorn National Forest; and (POP3) a custom boundary with sub-populations, Bighorn National Forest Districts. All examples can be used with any population, standard or custom.

Example FIA plot data from FIADB
The examples use FIA plot data from FIA Evaluation 561301, including
three inventory years of field measurements in the state of Wyoming,
from FIADB_1.7.2.00, last updated June 20, 2018, downloaded on June 25,
2018, and stored as internal data objects in FIESTA.

| WYcond | WY condition-level data |
| WYtree | WY tree-level data |
Example Auxiliary data
Auxiliary data for state-level estimates, including plot-level
estimation unit and stratum assignments; area by estimation unit; and
pixel counts by strata class and estimation unit, were downloaded from
FIADB at the same time, from the same FIA Evaluation (i.e., 561301), and
stored as internal data objects in FIESTA. Estimates using
auxiliary data from FIADB can be compared with EVALIDator estimates,
using the 2013 evaluation (https://apps.fs.usda.gov/fiadb-api/evalidator).
Auxiliary data for the custom boundaries are summarized from spatial layers stored as external objects in FIESTA, originating from the USDA Forest Service, Automated Lands Program (ALP; 2018) and from a 250m resolution, Moderate Resolution Imaging Spectroradiometer (MODIS), classified map, reclassified from 3 to 2 classes: 1:forest; 2:nonforest (Ruefenacht et al. 2008)

Set up
First, you’ll need to load the FIESTA library:
Next, you’ll need to set up an “outfolder”. This is just a file path
to a folder where you’d like FIESTA to send your data
output. For this vignette, we have saved our outfolder file path as the
outfolder object in a temporary directory. We also set a
few default options preferred for this vignette.
Get auxiliary data for custom examples
Now, we need to get the auxiliary data for the custom boundaries. The FIESTA spGetStrata function is a spatial wrapper function to facilitate extraction and summary of user-defined spatial data used for post-stratification. The function uses the FIESTA spExtractPoly and spExtractRast functions to subset (i.e., clip) plots to the boundary and extract values from estimation unit (i.e., polygon) and strata values (i.e., raster) to plot center locations, respectively. Other internal spatial functions calculate stratum pixel counts and area by estimation unit. If a polygon strata layer is given, the FIESTA spPoly2Rast function converts the polygon layer to raster before calculating strata weights.
Our custom examples demonstrate how to get data for one area of interest, or population (e.g, Bighorn National Forest) and for one area of interest, with multiple estimation units, or subpopulations (e.g., Bighorn National Forest Districts).

FIESTA’s population functions (mod*pop)
check input data and perform population-level calculations, such as:
summing number of sampled plots; adjusting for partial nonresponse; and
standardizing auxiliary data. These functions are specific to each
FIESTA module and are run prior to or within a module for
any population of interest.
For FIESTA’s GB Module, the modGBpop
function calculates and outputs: number of plots, adjustment factors,
and an expansion factor by strata. The outputs are similar to data found
in FIADB’s pop_stratum table. The output from modGBpop can
be used for one or more estimates from modGBarea,
modGBtree, or modGBratio functions.

View Example
In this example, we use the sample Wyoming data (2013 Evaluation)
stored in FIESTA to generate population data for the GB
module. We check this output with the FIADB pop_stratum table from FIA
DataMart for 561301 Evalid, using the FIESTA::DBqryCSV
function.
GBpopdat <- modGBpop(
popTabs = list(cond = FIESTA::WYcond, # FIA plot/condition data

strata = TRUE, # if using post-stratification
stratalut = WYstratalut, # strata classes and pixels counts
strata_opts = strata_options(getwt = TRUE) # strata options
)To get the names of the list components associated with the output of
our call of modGBpop, we run the following code:

View Example
In this example, we use the sample WY plot data (2013 Evaluation) in
FIESTA and output from spGetStrata to generate population
data for the Bighorn National Forest. Here, we have only one estimation
unit within the population of interest (i.e., Bighorn National Forest),
therefore strata and pixel counts are summarized to the population.
If the FIESTA::spGetStrata function is used to obtain
stratification data, the output list object can be input directly into
modGBpop through the GBstratdat parameter. If
other methods are used, the data are input through individual
parameters.

View Example
In this example, we use the sample Wyoming plot data (2013
Evaluation) stored in FIESTA and output from spGetStrata to
generate sub-population data for Bighorn National Forest Districts.
Here, we have more than one estimation unit (i.e., sub-population)
within the population of interest (i.e., Bighorn National Forest
Districts), therefore strata and pixel counts are summarized by each
District within the population.
If the FIESTA::spGetStrata function is used to obtain
stratification data, the output list object can be input directly into
modGBpop through the GBstratdat parameter. If
other methods are used, the data are input through individual
parameters.

View Example
In this example, we use the sample Rhode Island data (441901
Evaluation) stored in a SQLite database as external data in
FIESTA. Data were extracted from the FIA database on June
6, 2022. All output can be compared with output from other FIA
tools.
First, let’s look at the SQLite database. Use the DBI package explore the contents.
SQLitefn <- system.file("extdata", "FIA_data/RIdat_eval2019.db", package="FIESTA")
conn <- DBI::dbConnect(RSQLite::SQLite(), SQLitefn)
DBI::dbListTables(conn)
DBI::dbDisconnect(conn)GBpopdat.RI <- modGBpop(popTabs = list(plt="plot", cond="cond", tree="tree", seed="seed"),
dsn = SQLitefn,
pltassgn = "pop_plot_stratum_assgn",
stratalut = "pop_stratum",
unitarea = "pop_estn_unit",
unitvar = "ESTN_UNIT",
areavar = "AREA_USED",
strata_opts = list(getwt=TRUE, getwtvar="P1POINTCNT")
)
names(GBpopdat.RI)
# Strata-level population data, including number of plots and adjustment factors
GBpopdat.RI$stratalut modGBarea()
FIESTA‘s modGBarea function generates acre
estimates by domain (e.g., Forest type). Calculations are based on Scott
et al. 2015 (’Green-Book’) for mapped forest inventory plots. The
non-ratio estimator for estimating area by stratum and domain is used.
Plots that are totally nonsampled are excluded from the estimation
dataset. Next, an adjustment factor is calculated by strata to adjust
for nonsampled (nonresponse) conditions that have proportion less than
1. The attribute is the proportion of the plot which is divided by the
adjustment factor, and averaged by stratum. Strata means are combined
using the strata weights and then expanded to acres using the total land
area in the population.
If there are more than one estimation unit (i.e., subpopulation)
within the population, estimates are generated by estimation unit. If
sumunits=TRUE, the estimates and percent standard errors
returned are a sum combination of all estimation units. If
rawdata=TRUE, the raw data returned will include estimates
by estimation unit.
Parameters defined in the following examples are organized by category: population data (pop); estimation information (est); and output details (out).
POP1: 1.1 Area of forest land, Wyoming, 2011-2013
View Example
Using the modGBarea function we generate estimates by
estimation unit (i.e., ESTN_UNIT) and sum to population (i.e., WY).
FIESTA then returns raw data for area of forest land,
Wyoming, 2011-2013 (sum estimation units). Note that we set some options
for our table output with the table_opts argument. For a
full list of possible table options, you can run
help(table_options).
The following estimates match output from EVALIDator using the WY 2013 Evaluation.
area1.1 <- modGBarea(
GBpopdat = GBpopdat, # pop - population calculations for WY, post-stratification
landarea = "FOREST", # est - forest land filter
sumunits = TRUE # est - sum estimation units to population
)To get the names of the list components associated with the output of
our call of modGBarea, we run the following code:
output
## [1] "est" "raw" "statecd" "invyr"To easily access our estimate and percent sampling error of estimate
we can just grab the est object from out outputted
list:

View Example
In this example, we look at adding rows and columns to output,
including FIA names. We also output estimates and percent standard error
in the same cell with the allin1 argument in
table_options and save data to an outfolder with the
outfolder argument in savedata_options.
## Area of forest land by forest type and stand-size class, Wyoming, 2011-2013
area1.3 <- modGBarea(
GBpopdat = GBpopdat, # pop - population calculations for WY, post-stratification
landarea = "FOREST", # est - forest land filter
rowvar = "FORTYPCD", # est - row domain
colvar = "STDSZCD", # est - column domain
sumunits = TRUE, # est - sum estimation units to population
savedata = TRUE, # out - save data to outfolder
returntitle = TRUE, # out - return title information
table_opts = list(
row.FIAname = TRUE, # table - row domain names
col.FIAname = TRUE, # table - column domain names
allin1 = TRUE # table - return output with est(pse)
),
savedata_opts = list(
outfolder = outfolder, # save - outfolder for saving data
outfn.pre = "WY" # save - prefix for output files
)
)We can again look at the output list, estimates, raw data, and titles:

FIESTA‘s modGBtree function generates tree
estimates by domain (e.g., Forest type) and/or tree domain (e.g.,
Species). Calculations are based on Scott et al. 2005 (’the green-book’)
for mapped forest inventory plots. The non-ratio estimator for
estimating tree attributes by stratum and domain is used. Plots that are
totally nonsampled are excluded from estimation dataset. Next, an
adjustment factor is calculated by strata to adjust for nonsampled
(nonresponse) conditions that have proportion less than 1. Attributes
adjusted to a per-acre value are summed by plot, divided by the
adjustment factor, and averaged by stratum. Strata means are combined
using the strata weights and then expanded to using the total land area
in the population.
If there are more than one estimation unit (i.e., subpopulation)
within the population, estimates are generated by estimation unit. If
sumunits = TRUE, the estimates and percent standard errors
returned are a sum combination of all estimation units. If
rawdata = TRUE, the raw data returned will include
estimates by estimation unit.
Parameters defined in the following examples are organized by category: population data (pop); estimation information (est); and output details (out).
The following reference table can be used for defining
estvar and estvar.filter:

Now, we can generate estimates by estimation unit (i.e., ESTN_UNIT)
and sum to population (i.e., WY) with modGBtree:
## Return raw data and titles
## Total net cubic-foot volume of live trees (at least 5 inches diameter), Wyoming, 2011-2013
tree1.1 <- modGBtree(
GBpopdat = GBpopdat, # pop - population calculations
landarea = "FOREST", # est - forest land filter
sumunits = TRUE, # est - sum estimation units to population
estvar = "VOLCFNET", # est - net cubic-foot volume
estvar.filter = "STATUSCD == 1", # est - live trees only
returntitle = TRUE # out - return title information
)We can now take a look at the output list, estimates and percent sampling errors, raw data, and titles:

FIESTA‘s modGBratio function generates
per-acre and per-tree estimates by domain and/or tree domain by domain
(e.g., Forest type) and/or tree domain (e.g., Species). Calculations are
based on Scott et al. 2005 (’the green-book’) for mapped forest
inventory plots. The ratio estimator for estimating per-acre or per-tree
by stratum and domain is used, referred to as Ratio of Means (ROM).
If there are more than one estimation unit (i.e., subpopulation) within the population, estimates are generated by estimation unit. If sumunits = TRUE, the estimates and percent standard errors returned are a sum combination of all estimation units. If rawdata = TRUE, the raw data returned will include estimates by estimation unit.
Parameters defined in the following examples are organized by category: population data (pop); estimation information (est); and output details (out).
POP1: 1.1 Net cubic-foot volume per acre of live trees on timberland, Wyoming, 2011-2013
View Example
We generate estimates by estimation unit (i.e., ESTN_UNIT) and sum to population (i.e., WY):
## Return raw data and titles
## Total net cubic-foot volume of live trees (at least 5 inches diameter), Wyoming, 2011-2013
ratio1.1 <- modGBratio(
GBpopdat = GBpopdat, # pop - population calculations
landarea = "TIMBERLAND", # est - forest land filter
sumunits = TRUE, # est - sum estimation units to population
estvarn = "VOLCFNET", # est - net cubic-foot volume, numerator
estvarn.filter = "STATUSCD == 1", # est - live trees only, numerator
returntitle = TRUE # out - return title information
)And we can look at our output:

If you just wanted estimates by estimation unit and did not want to
sum them, set sumunits = FALSE. If
sumunits = FALSE, the estimates and percent standard errors
returned are by estimation unit, with an attribute, named ‘unit’
appended to data frame, with the unit value. The raw data returned will
look the same as if sumunits = TRUE.
