OSGeo-Live 11.0 has been released! It has been a major reboot, with a refocus on leading applications and emphasis on quality over quantity. Less mature parts of the projects have been dropped with a targeted focus placed on upgrading and improving documentation. There is now support for isohybrid ISO images with UEFI

52°North’s latest SOS version is now available on OSGeo-Live! (more…)

GSoC2017 - M.M.Don

My experience with the GSoC 2017 project “Simple Features for Protobuf and others” came to an end by presenting my results at the Geospatial Sensor Webs Conference 2017. It was really pleasing to see that a majority of the audience was really interested in the project outcome and eager to see it progress in the future. (more…)

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…)

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.
