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)
)
Arguments
destdir |
where to save files, defaults to |
load |
|
... |
(optional) arguments passed to |
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: |
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.
Note
Because of R-compatibility and easy readability reasons, the downloaded
dataset is a modified version of the original, WSM server version:
All column names have been changed from uppercase (in the original dataset) to
lowercase characters.
Unknown azimuth values are represented by NA
values instead of 999
in
the original.
Unknown regimes are represented by NA
instead of "U" in the original.
