[SensorML] SensorML

Is there a (plan for) a registry of SensorML profiles or models?

Hi WenZhan.

Sorry to take so long responding. Thanks for sending me a reminder.

I'm assuming that what you mean by "whether SensorML has defined those
standards or not", is whether or not we have developed profiles or example
instances of those sensors. 

Last year, I began looking at the SEEDS (Standard for the Exchange of
Earthquake Data) standard for seismic data and found that it was extremely
compatible with SensorML ... The SEEDS description of the sensor system that
can accompany a seismic observation, essentially describes a process chain
similar to the SensorML approach. Components in the chain include the
seismometer, amplifier, analog filters, decimator, and digital filters
(referred to as stages in SEEDS). To support these we created a few
necessary Digital Signal Processing components, including Finite Impulse
Response (FIR), Infinite Impulse Response (IIR), gain, decimator, and Poles
and Zeroes. The seismometer can be supported by the generic detector model
in SensorML, although one may wish to create a profile for that (more about
creating profiles in SensorML later). Our activities with the seismic
sensors ended when the contract ended, so these process models have not been
updated from the previous SensorML version, nor were they put into a
complete chain to demonstrate a real example. That contract is starting back
up, so maybe I can revisit that effort soon.

That said, I understand "through the grapevine" that someone has separately
created a SensorML "profile" or examples for seismic sensors, but I need to
track down that effort assuming that its not hidden behind secure firewalls
(if you're out there, please speak up).

With regard to GPS, there have been several initial examples of SensorML
descriptions for GPS sensors (mostly in the previous SensorML version).
Since each GPS is different and since different people have chosen to show
only particular types of output (e.g. NMEA, or proprietary formats), each of
these descriptions have been slightly different (in other words there is no
one "standard" way to describe a GPS sensor). I need to gather these up and
change the examples to SensorML V1.0, but I would be able to get to that
until a few weeks. If anyone else has examples, please submit them for
perusal.

For infrasonic and lightening sensors and their observations, I know of no
particular examples having been created but we have described several
similar sensor and data types in SensorML / SWE Common. If you want to send
me more detailed information about what you have in mind, perhaps I can
point you in the right direction or help out.

Thanks.
Mike Botts
