All notable changes for the SIGMA package and its applications will be documented in this file.
Add configuration options to autosigma for map rendering
map.grayscale = true|false
map.station.annotation = true|false
map.station.triangle = true|false
map.event.legend = true|false
`map.grid.composition = default|src|src-over|xor|plus|multiply
Add timeout option for export script
output.exportTimeout = 60
Remove map plugins from default configuration.
Update documentation on plugins.
Update documentation of GMPE configuration.
Notify with rupture must be defined for GMPEs.
Add option to configure alignment of the scale layer legend as
Add configurable grid/image export to autosigma. PGA/MMI is enabled by default and PGV is disabled by default.
Updated references in documentation.
Added more GMPEs to documentation of internal GMPEs.
Do not run computation for events smaller than the configured minimum magnitude threshold.
Remove incidents if magnitude drops below the configured threshold.
Add selection of grids to be exported in Sigma. The default is PGA and MMI. Additionally PGV can be selected. Grids and images are being named “grid-[pga|pgv|mmi]” and “map-[pga|pgv|mmi]” respectively.
Example export script for autosigma, @DATADIR@/sigma/scripts/export-autosigma.sh, defined in
Documentation of autosigma output and configuration.
Documentation of amplitudes: psa_0_3, psa_1_0, psa_3_0, snrPd, pdPvR in sigma plugins.
Documentation of shake map parameters in Sigma.
Add database and fdsnws source to default configuration.
Add event database and fdsnws source to documentation of installation.
Incident map symbols shown from the various import dialogs are not inveractive and the incident will be loaded on double-click.
gmpe.groupsparameter for sigma to description XML allowing configuration in scconfig.
Instructions on installation and configuration of external GMPEs.
Install script for software dependencies on Ubuntu 20.04.
Fixed exit code of autosigma when run offline. Instead of “sometimes” 1 it now returns 0.
Add button to focal mechanism dialog to reset it to the solution of the incident if present.
Replace focal mechanism edit buttons to select the preferred nodal plane with radio buttons.
Update documentation and add an example script to autosigma for treating output files.
New internal GMPE IMP-PV09 for Iceland.
Update GMPE documentation including IMO-PV09 and references.
Improve lookup of Vs30 grid.
Fix orientation output grid.
Added support for design spectra definition per station code or location code. Files must be provided in
Changed location for depth layers from
Plot design spectrum in the processing details panel
Exported traces (
*.slist) include noise window. Also the processed signal time window plots for acceleration, velocity and displacement include the noise window.
Added the documentation of the filter and the noise parameters of the sigmaamps plugins.
The Save screenshot command exports now the tab currently active, either map, plot or traces whereas only the map tab supports arbitrary output sizes. All other tabs will be saved with the size currently set.
Station symbols are now configurable. It can be selected between “diamond” (default) and “triangle” (SeisComP style). It can be controlled with parameter
scheme.map.stationSymbol. Furthermore the symbol can be changed during runtime in the view options.
Expect velocity layer files in
GMPE plugins can return an error message and sigma as well as autosigma output this message if an operation such as PGA computation failed.
If contour rendering was enabled, then some levels where incorrectly coloured when district rendering was enabled too. That has been fixed.
Added parseincident script for SIGMA report generation with configuration and documentation.
sigma pre-selects by default all stations which are included in the event location and magnitude computation if the event is imported from SeisComP.
autosigma/sigma waits for an image to be generated if used in combination with async tile loaders such as OSM.
Added more log output if an event is loaded to track how channels are initially activated.
Fixed PSA computation for periods at 0s and -1s
Parse sensor unit case insensitively which evaluates m/s and M/S equally
Added PSA value table to processing result page
If SeisComP events are imported, then preselect stations which are associated with the preferred magnitude. If the preferred magnitude does not have any contributions then all stations associated with the origin will be selected.
Added SNR computation which is shown in the result page and stored in the database as additional parameter. The SNR is computed as
max(signal) / max(noise).
Export Surfer grid file for pga/mmi (autosigma) or currently active grid type (sigma). The file is named either “grid-pga.grd”, “grid-pgv.grd” or “grid-mmi.grd”.
Fixed QPixmap warning in autosigma when generating map images
sigma received a new parameter to configure the default export directory like autosigma with
Unify sigma and autosigma configuration. In sigma the following parameters have changed in scconfig and take precedence over the old ones. The old ones are still active but not documented anymore:
database.output -> output.database scripts.export -> output.exportScript
