At this time you must install the tidyFIA package via GitHub.

remotes::install_github("SilviaTerra/tidyFIA")

The main function is tidy_fia which will import the specified tables from FIADB that correspond to an area of interest represented by a geospatial object in R (class sf) or a list of state abbreviations (e.g. c("CA", "NV")).

To get started you can simply run this example command to get the FIA tables for the state of Minnesota:

mn_data <- tidyFIA::tidy_fia(
  states = "MN",
  postgis = TRUE
)

SilviaTerra is hosting the FIADB data in a PostGIS database. Please reach out to Henry Rodman if you would like the password for the database. Alternatively you can ask tidy_fia to download and import the data directly from the CSVs stored at the FIA datamart by setting the parameter postgis to FALSE. This is slower than querying the database but will work without any authentication.

The example will import these tables by default: "plot", "subplot", "cond", "tree", "survey"

Each table is an element in the list mn_data. To use one of the tables you call them like this:

mn_data[["plot"]]
mn_data[["tree"]]
...
