A simple Python module to query an IOOS SOS service for active sensors and output ISO 19115-2-compliant xml metadata following a template.
Preliminary SensorML parsing code adapted for this module from NANOOS.
git clone https://github.com/ioos/sensorml2iso.git
cd sensorml2iso
python setup.py install
sensorml2iso -s http://data.nanoos.org/52nsos/sos/kvp
or, with all optional parameters:
sensorml2iso -s http://data.nanoos.org/52nsos/sos/kvp -d 14 --stations=urn:ioos:station:nanoos:apl_nemo,urn:ioos:station:nanoos:apl_npb1ptwells
--getobs_req_hours 3 --response_formats='application/json,application/zip; subtype=x-netcdf' --output_dir data.nanoos.org --verbose
Parameters:
-s | --service : SOS service endpoint URL
-d | --active_station_days : (Optional) Number of days from present to use to filter SOS stations
not actively reporting observations for active/inactive designation. Inactive stations are
excluded from processing.
--stations : (Optional) Comma-separated list of station URNs to filter by.
Eg. '--stations=urn:ioos:station:nanoos:apl_nemo,urn:ioos:station:nanoos:apl_npb1ptwells'.
--getobs_req_hours : (Optional) Number of hours from last valid station observation time to use
in GetObservation request example URLs. Default: 2.
--response_formats : (Optional) Comma-separated list of SOS responseFormats to use in creating
GetObservation download links for each observed parameter.
Eg. "--response_formats='application/json,application/zip; subtype=x-netcdf'".
Default: ['application/json', 'text/xml; subtype="om/1.0.0/profiles/ioos_sos/1.0"'].
--output_dir : (Optional) Specify an output directory (relative to current working directory)
to write ISO 19115-2 XML files to. If omitted the default output directory will a subdirectory
using the domain name of the SOS service URL passed (eg. sos.gliders.ioos.us).
--sos_type: (Optional) Identify the type of SOS service to query. Currently this isn't implemented,
but could be used to use specific parsers built into the Pyoos library. Valid types: 'ioos', 'ndbc', 'coops'.
--verbose : (Optional) verbose output to stdout and log file sensorml2iso.log
To run the command using docker:
docker run -v $PWD/iso:/srv/iso --name sensorml2iso -it --rm ioos/sensorml2iso -s http://sos.glos.us/52n/sos/kvp --output_dir /srv/iso/glos
To run the container as a service:
