GIS linked to WoT

With this blog post Iwould like to wrap up my Google Summer of Code work for 52°North. And since pictures say more than a thousand words, I prepared a video about my project “GIS link to the Web of Things“.

The video aims at introducing the Arduino SenseBox’s various features. The final version fulfills the pre-development objective of the “GIS link to the Web of Things”. “Things” refer to the Local Sensor Module of Arduino which is bridged to standard GIS software, such as Google Earth and the ESRI JavaScript API-based clients. In layman language, the SenseBox stores sensor measurements and other information locally and provides it to client software via the Geoservices REST API in JSON or KML encoding.


The SenseBox features can be divided into three functional parts: (more…)

52°North software on OSGeo-Live 6.0

OSGeo-Live 6.0 is released. For this release,  all OSGeo-Live java applications have been successfully migrated to OpenJDK 7. Migration to OpenJDK was driven by Oracle’s announcement that including Sun Java in Linux distributions, such as Ubuntu, or OSGeo-Live, is no longer allowed. In addition, the Xubuntu base has been upgraded to 12.04 LTS (Long Term Support).

With this version, you can try running instances of the following 52°North service implementations:

  • 52°North SOS version 3.5 Just go to GeospatialWeb ServicesStart 52°North SOS to start testing. Firefox will open with three tabs:
    • a client to test the SOS
    • a quickstart page to get things started
    • a documentation page about the 52°North SOS implementation
  • 52°North WPS version 3.0 Just go to GeospatialWeb ServicesStart 52°North WPS to start testing:
    • a simple client to test the WPS
    • a quickstart page to get things started
    • a documentation page about the 52°North WPS implementation
  • 52°North WSS version 2.2.0 Just go to GeospatialWeb ServicesStart 52°North WSS to start testing:
    • a client to test the WSS
    • a quickstart page to get things started
    • a documentation page about the 52°North WSS implementation

Just give it a try and test a lot of geospatial applications without the need to install any of them. The OSGeo Live DVD contains software for the following categories, and it is all FOSS:

Online demo resources are available on the demo servers of the communities:

I hope you enjoy testing our SOS, WPS and WSS.

Demonstrating Exchangeable Encodings for SOS: A Quantum Leap for me

The final sprint towards the end of the Google Summer of Code (GSoC) is over now. After fixing bugs, working on documentation and actually producing time-series in different formats, the “Exchangeable Encodings for SOS” project met most of its ambitious goals – and it is demonstrated on the 52°North Google summer of Code Demo Server. Users and developers documenation on the encoding mechanism has also found a place in the 52°North wiki.

We have integrated a plugin mechanism into an SOS server (source code branch), which is based on the main 52°North SOS development line (source code trunk). As a proof of the concept, two basic plugins are provided:

  • Plain CSV (comma separated values) response format, which tries to stick to recommended NOAA IOOS Data Integration Framework CSV output,
  • WaterML 2.0 (OGC WaterML 2.0 and Hydro DWG). I acquired a recent version of the WaterML 2.0 encoding profile, which is already adopted as a (candidate) standard. The schemas are not yet officially published and rumours have it that there might be last minute changes. The change request contains an extension regarding empty time-series responses which should not interfere with the existing implementation.

In the world of many diverse forms of observation types for natural phenomena, the two plugins demonstrated both rely on point-based measurement data.

Where to go from here? (more…)

SOS Importer 0.2.0 Development Version Released

August 22nd, 2012 @ 13:56 by Eike Juerrens
Posted in Communities, Sensor Web

Last Friday, a new version of the SOS (Sensor Observation Service) Importer was released. This 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 0.2 offers the following new features:

  • Maven build
  • multi language support
  • XML configuration
  • generation of features of interests (FOIs) and other data from columns
  • feeding component

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 ;-)).
