pyacs.gts.lib.metadata module¶
-
pyacs.gts.lib.metadata.read_lon_lat(self, gmt_file, verbose=False)[source]¶ Reads a gmt psvelo file and populates Gts.lon & Gts.lat
- Parameters
gmt_file – gmt psvelo file
verbose – verbose mode (boolean)
- Returns
the current Gts instance
-
pyacs.gts.lib.metadata.save_velocity(self, gmt_file, verbose=True, comment=None, up=False)[source]¶ Appends velocity estimates (with uncertainties) to a gmt psvelo file
- Parameters
gmt_file – output gmt psvelo file (will append if gmt_file already exists)
verbose – verbose mode (boolean)
comment – comment as a string. ‘# ‘ is pre-prended to comment if not provided
up – boolean. If True, then Ve, SVe and SVen are set to 0 and Vu and Vu are written as 4-th and 6-th fields
- Returns
the current Gts instance
-
pyacs.gts.lib.metadata.save_offsets(self, ofile, verbose=True, comment='', up=False, info=False)[source]¶ Appends offsets values to a given text file (gmt psvelo format)
- Parameters
ofile – output offset file
verbose – verbose mode (boolean)
comment – comment as a string. ‘# ‘ is pre-prended to comment if not provided
up – boolean. If True, then Ve, SVe and SVen are set to 0 and Vu and Vu are written as 4-th and 6-th fields
- Returns
the current Gts instance
-
pyacs.gts.lib.metadata.read_eq_rename(self, eq_rename, in_place=False, verbose=False)[source]¶ Reads the information for the current site (code) from an eq_rename globk file.
Populates loutliers and offsets_dates Found excluded periods in the eq_rename file are added to loutliers
- Parameters
eq_rename – eq_rename (globk format) file to be read
in_place – boolean. If True then the Gts instance is modified, if False the Gts instance is preserved and a new Gts instance is return
verbose – verbose mode (boolean)
- Returns
Gts instance
-
pyacs.gts.lib.metadata.save_eq_rename(self, eq_rename, verbose=False, excluded_periods=None)[source]¶ save results of a Gts analysis in globk format eq_rename
- Parameters
eq_rename – output eq_rename file (Golbk format)
verbose – verbose mode (boolean)
exluded_periods – periods to be excluded
- Returns
Gts instance
-
pyacs.gts.lib.metadata.make_dynamic_apr(self, apr, time_step=30.0, pos_tol=0.03, dates=[], gap=20.0, verbose=False)[source]¶ Creates an apr file for GAMIT The created apr file has no velocity, but a series of coordinates at different time
- Parameters
apr – apr file (Globk format)
time_step – time step for writing dates (default 30 days)
pos_tol – position tolerance. If exceeded, a new date will be written. (default 0.03 m)
dates – a list of dates in decimal years where writing will be forced
gap – gap in days. If there is no data during a duration greater than gap, then observation is forced to be included and tested against pos_tol
verbose – verbose mode (boolean)
- Returns
Gts instance
-
pyacs.gts.lib.metadata.save_apr(self, apr, epoch=None, verbose=False, excluded_periods=None)[source]¶ save results of a Gts analysis in globk format apr file
- Parameters
apr – apr file (Globk format)
epoch – epoch in decimal year for coordinates in apr
verbose – verbose mode (boolean)
exluded_periods – periods to be excluded
- Returns
Gts instance
- Note
following Globk’s convention, site will be named XXXX_1PS, XXXX_2PS etc between offset dates
-
pyacs.gts.lib.metadata.read_offset_dates(self, offset_file)[source]¶ Reads an offset file and populates offsets_dates (pyacs format) attribute of the current Gts instance. format is simply a code dates. dates can be any format read by pyacs.guess_date
- Parameters
offset_file – offset_file to be read
- Returns
the current Gts instance
