sensor details metadata #79

Closed caro-gns closed 3 years ago

caro-gns commented 3 years ago

This command line: https://service.geonet.org.nz/fdsnws/station/1/query?network=NZ&station=WTMC&level=channel&format=text states that WTMC has a strong motion sensor from 2010 then an accelerometer from 2017. Are these the same sensors? And if so how can I find out if these are Kinemetrics basalt or cusp or etc... please? Thank you !

Two options, either try using level=response in the command line (you will also need to remove the format=text option) above (rather than level=channel). This will give a full output of the response in XML, which you may need to format (on linux etc I use xmllint --format filename.xml to do this ... e.g. a snippet:

        <Sensor resourceId="Sensor#CUSP3B:309">
          <Type>Strong Motion Sensor</Type>
          <Description>CUSP 3B</Description>
          <Manufacturer>Canterbury Seismic Instruments</Manufacturer>
          <Model>CUSP3B</Model>
          <SerialNumber>309</SerialNumber>
          <InstallationDate>2005-11-15T01:00:00</InstallationDate>
          <RemovalDate>2010-03-25T22:30:00</RemovalDate>
        </Sensor>

or you could check the raw source of the data in the https://github.com/GeoNet/delta repo. The information in this instance will be buried in https://github.com/GeoNet/delta/blob/main/install/recorders.csv . I'd suggest the first option as it's the more formal approach.

The subtlety between a "Strong Motion Sensor" and an "Accelerometer" is another topic ... (but from the outside in a data sense, they are the same thing).

Hi @caro-gns ,

thanks to @ozym's reply I think this ticket can be now closed. Please re-open it if you think more details are needed.
