import_WSM2016: World Stress Map Database (WSM) Release 2016

Description

Download WSM2016 database from the GFZ sever and applies optional filters. If destdir is specified, the data can be reloaded in a later R session using load_WSM2016() using the same arguments.

Usage

download_WSM2016(destdir = tempdir(), load = TRUE, ...)
load_WSM2016(
  file,
  quality = c("A", "B", "C", "D", "E"),
  lat_range = c(-90, 90),
  lon_range = c(-180, 180),
  depth_range = c(-Inf, Inf),
  method = c("BO", "BOC", "BOT", "BS", "DIF", "FMA", "FMF", "FMS", "GFI", "GFM", "GFS",
    "GVA", "HF", "HFG", "HFM", "HFP", "OC", "PC", "SWB", "SWL", "SWS"),
  regime = c("N", "NS", "T", "TS", "S", NA)
)

Value

sf object of and the parsed numeric uncertainty (unc) based on the reported standard deviation and the quality rank. If load=FALSE, the path to the downloaded file is returned.

Arguments

destdir

where to save files, defaults to base::tempdir(), base::getwd() is also possible.

load

TRUE load the dataset into R, FALSE return the file name of the downloaded object.

...

(optional) arguments passed to load_WSM2016()

file

the name of the file which the data are to be read from.

quality

a character vectors containing the quality levels to be included. Includes all quality ranks (A-E) by default.

lat_range, lon_range

two-element numeric vectors giving the range of latitudes and longitudes (in degrees).

depth_range

two-element numeric vectors giving the depth interval (in km)

method

a character vectors containing the methods of stress inversion to be included. Includes all methods by default. See WSM2016 manual for used acronyms.

regime

a character vectors containing the stress regimes to be included. Acronyms: "N" - normal, "T" - thrust, "S" - strike-slip, "NS" - oblique normal, "TS" - oblique thrust, and NA - unknown faulting
