WPS and Artifical Neuronal Networks

Filed Under: 52°North, Communities, Geoprocessing

We often get asked about why our WPS can’t a show how long a process would take. This task is not trivial, in fact it is quite challenging to determine in advance or at runtime how long a specific process will take. Many factors have to be taken into account such as the server load, the process itself, the inputdata etc.

One idea would be to utilize Artifical Neuronal Networks (ANN) to train a WPS. This might be a good starting point for a M. Sc. thesis. If you are interested in this topic, please contact Bastian Schäffer b.schaeffer A/T 52north.org

Monday and Tuesday, Arne attended the ESONET workhop in Marseille. Together with Dan Toma, Joaquin del Rio (both from SARTI) and Tom O’Reilly (from MBARI), we gave a demo to show the interplay of the PUCK protocol and our Sensor Interface Descriptors (SID) to establish a plug and play of sensors.

Last Monday, Arne went to Hamburg to attend the 2nd PESOS workshop and gave a talk about our Sensor Interface Descriptor (SID) developments. The workshop participants were primarily sensor technology manufacturers and vendors as well as researchers from that domain. The workshop aimed at initializing a discussion of how SID can be reasonably combined with other standards such as IEEE 1451 and the emerging PUCK protocol. The overall goal for the participants is to elaborate a concept for plug & play of marine sensors. The figure below sketches how the 3 discussed technologies could work together to enable an on the fly integration of sensors with the Sensor Web.

WPS & GRASS

Our Experiments with GRASS and WPS are going well.

As a little Christmas gift, we will prepare a new Release (52n WPS 2.0 RC-6) before Christmas.

It will contain a connector to GRASS which allows the out-of-the-box use of GRASS Functions as WPS Processes. No programming will be needed.

List,

this is an information that an WPS 2.0-RC6 Release will come before
Christmas.
It will mainly contain a connection to GRASS in an out-of-the-box way. A
subset of GRASS Processes will then be available as WPS Processes
without any programming needed.

Bastian Schäffer
