A look into WPS branches – Today: Spacebel

Posted in Geoprocessing

The 52°North WPS implementation shares one important property with the specification – it is very flexible and can be used for many different use cases. A number of parties contribute, which  results in a number of active development branches for code. We will present a selection in blog posts over the next few months.

Spacebel takes the 52°North WPS to space.

Their extensions target the requirements of satellite data processing with service oriented architectures for a future proof and flexible infrastructure. A processing on-demand WPS extension allows the user to dynamically deploy and un-deploy processes, as well as auxiliary data, steer the execution of processes, monitor/audit the executed processes, download processing results, and discover processes and workflows.

These features are developed to support the Heterogeneous Missions Accessiblity (HMA) on-demand processing scenario [1], in which earth observation (EO) data shall be processed. This is mostly satellite data and therefore comes with a few challenges, most importantly, the sheer size of the data. The volumes are so large that this will never work without processing power close to the data (no remote internet access) and a parallel processing infrastructure, such as a Grid Computing or Cloud environment. This way, an analyst/a scientist must not run his own processing facilities, but can remotely start and control processes. Overhead for data transfer are also minimized. Such a framework additionally allows users of the processing chains to share deployed processes.

Moreover, these developments allow (more…)

Visualization Tool Assessment

The UncertWeb FP7 EU project has developed methods and open source tools for uncertainty propagation in web-enabled environmental modeling chains. One of these tools visualizes probabilistic spatial and spatio-temporal data in a browser. To assess the usability of this visualisation tool, the Institute for Geoinformatics prepared an online survey.
Please take the time and spend 20 minutes to get to know the tool and give your opinion about it! We will need this before Jan 15, 2013 23:59 UTC.

The questionnaire is available here.

For those of you who are curious, yes, this is the tool that will continue under the name GREENLAND!

ArcGIS Server SOS Extension – podcast

As reported earlier, we have implemented an SOS extension for ArcGIS Server as a so-called Server Object Extension (SOE). We have developed this software for the European Environment Agency (EEA) and in support of ESRI Inc.

The ArcGIS Server SOS Extension is compliant with the Sensor Observation Service (SOS) 2.0 standard defined by OGC. Additionally, the SOE provides a new REST interface to sensor resources which complies to the Geoservices REST API developed by ESRI, which is currently going through the standardization process at OGC.

More details on this development (e.g., demo, download link, SVN access, installation instructions, etc.) can be found on the project’s website.

Today, I’d like to point out a recently published interview of Peter Kjeld (EEA), Satish Sankaran (ESRI), and Andreas Wytzisk (52°North) who explain about this mutual development and further plans with this software:

A detailed illustration of the functionality of the ArcGIS SOS extension is provided by the following screencast:

SOS Importer 0.3.0 Development Version Released

Posted in Sensor Web

Today, a new version of the SOS (Sensor Observation Service) Importer was released. It is a tool for importing observations from CSV (Character Separated Values) files into a SOS instance using an eight step wizard for guiding a user through the often cumbersome process of data transformation.

Version 0.3 offers the following new features:

More details can be found on the Wiki page of the SOS importer.

You can download the binaries from our Maven release repository:

Alternatively, you can build the binary files from the source code.

Feel free to share your experience with the Sensor Web community in our forum or mailing list (choose which you want, they are synchronized ;-)).
