Usability improvements for smle – Midterm

smle /ˈsmaɪ.li/ is one of 52°North’s new developments. It is a SensorML editor based on TypeScript and Angular 2. The implementation of this editor  started earlier this year within the projects NeXOS and FixO3. The idea of the Google Summer of Code activity is to enrich the editor with further functionality and input fields.
After the one month of development in this GSoC project, we can see the progress and can give an insight into the current state of development. The introductory blog post with the plans for all the summer can be found here. (more…)

External Semester at 52°North

I am a student in the Master’s Program Geoinformatics at the University of Münster. The  Master’s program requires an external semester to gain practical experience. It is possible to either work in a research project at the university or have an internship in a governmental or industry institution. I chose 52°North because I like the idea of creating open source software. Open Source software is more accessible than closed software, in that it is possible to further develop and extend the software, so more people can contribute to it and benefit from it.

During this semester, I will work on two different projects. One project deals with the implementation of an extension for a metadata editor to simplify the search for sensors. In the second part of the semester, I will work on the enviroCar project. The enviroCar project provides a platform to visualize and analyze car data and discover more about driving behavior.

A look into WPS branches – Today: Conflation with Provenance

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 present a selection in blog posts in the series “A look into WPS branches”.

Conflation With Provenance – Custom WPS Processes

Similar to the efforts on Aviation-specific processing, 52°North developed processes for conflating two distinct data sets in the scope of the OWS 9 test bed. This article sheds some light on the details of the processes and the obstacles which need to be overcome.

Conflation is understood as a sophisticated process of unifying two or more separate data sets that share certain characteristics into one integrated all-encompassing dataset. In the process, different representations of a feature get folded into one feature. That target feature follows a particular model that is used to capture complementary information. In addition to the actual dataset conflation, the consistent capturing of provenance information was another goal of the project. The conflation processes developed represent a very customized and complex workflow. The test bed proved that the 52°North WPS framework fits perfectly into such use cases by providing an individual and flexible processing API.
