Spatial and temporal queries for FIADB
clipFIA.RdPerforms space-time queries on Forest Inventory and Analysis Database (FIADB). Subset database to include only data associated with particular inventory years (i.e., most recent), and/or only data within a user-defined region.
Usage
clipFIA(db, mostRecent = TRUE, mask = NULL, matchEval = FALSE,
evalid = NULL, designCD = NULL, nCores = 1)Arguments
- db
FIA.DatabaseorRemote.FIA.Databaseobject produced fromreadFIAorgetFIA. If aRemote.FIA.Database, data will be read in and processed state-by-state to conserve RAM (see details for an example).- mostRecent
logical; if TRUE, returns only data for most recent inventory.
- mask
sp or sf Polygon/MultiPolgyon object; defines the boundaries of spatial intersection with FIA tables.
- matchEval
logical; if TRUE, returns subset of data for which there are matching reporting years across states. Only useful if db contains mulitple state subsets of the FIA database.
- evalid
character; unique value which identifies an inventory year and inventory type for a state. If you would like to subset data for an inventory year other than the most recent, use
findEVALIDto look locate this value (see Examples below).- designCD
character vector; plot designs to include. Default includes standard national plot design with other similar sampling designs. See FIA Database User Guide Appendix 1 for descriptions of plot designs (see References).
- nCores
numeric; number of cores to use for parallel implementation. Check available cores using
detectCores. Default = 1, serial processing.
Details
Not required to run other rFIA functions, but may help conserve free memory and reduce processing time if user is interested in producing estimates for a specific inventory year or within a region not explicitly described in the database (w/in user defined polygons).
Spatial intersections do not adhere strictly to absolute plot locations, all plots which fall within an estimation unit (often a county) which intersects with a user defined region will be returned. The plots which fall slightly outside of the region do NOT bias estimates (removed from computations), but as FIA often employs stratified random sampling estimators, all plots within intersecting estimation units must be present to proudce unbiased variance estimates.
If specifying spatio-temporal intersections on a "Remote.FIA.Database", evaluation will occur state-by-state once called by an estimator function.
