FIADB-API (EVALIDator)

The Forest Inventory and Analysis Database API, the machine surface behind the EVALIDator web application. A single GET or POST to /fullreport returns population estimates with standard errors, variances and plot counts, grouped by row, column and optional page attributes, for one or more state/year evaluations. Every classed parameter has a live value dictionary at /fullreport/parameters/. Free, anonymous, CORS-open, and documented with worked Python and R examples.
