The Simple Feature Access Specification is a common standard that is widely used in geoinformatics for exchanging spatial features. It defines a common storage and access model for spatial vector geometries used by geographic information systems. Efficient serialization of this spatial data is a vital requirement in Spatial Data Infrastructures and Geoprocessing applications. (more…)

Caching for Sensor Web REST-API

There are only two hard things in Computer Science: cache invalidation and naming things.

Phil Karlton

Caching is a common technique to improve the response time of a data source. A cache is a temporary storage for a most often acquired data. Caching is widely used in a proxying software such as Squid. The caching of network responses can provide a huge improvement to the response time. The latency of a network resource is much more greater than of a memory or a disk resource [Fig.1]. That’s why the caching is a “must-have” feature of network proxies.

Usability improvements for smle – Final GSoC post

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 was to enrich the editor with further functionality and input fields.
As the Google Summer of Code 2016 comes to an end, we can see the results of the 13 week development period and compare it with the first plan described in the introductory blog post and with the interim results from the mid-term blog post. (more…)

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…)
