OSGeo-Live 7.0 has been released! For this release, geospatial applications have been updated to their latest stable release. OSGeo-Live is a self-contained bootable DVD, USB flash drive and Virtual Machine based upon Ubuntu Linux (version 12.04 LTS). OSGeo-Live is pre-configured with a wide variety of robust open source geospatial software. All applications can be trialled without installing anything on your computer, simply by booting the computer from a DVD or USB drive, or running in a Virtual Machine environment. Each featured package is accompanied by both a publication quality one page descriptive summary and a short tutorial on how to get started using it. more >
We are pleased to announce that the 52 ° North SOS 4.0.0 implementation supports two new features: the SOS 2.0 Spatial Filtering Profile and the support for the optional validTime parameter in DescribeSensor requests. Both features will facilitate the modelling, storage and retrieval of mobile sensor data from SOS.
Spatial Filtering Profile
The Spatial Filtering Profile is specified in clause 12 of the SOS 2.0 specification (OGC 12-006). This profile restricts observations to spatial observations which provide a well-defined parameter for the observation location. This parameter carries the sampling geometry of the observation which represents the spatial extent where the observation result applies to and can be targeted by spatial filters. The “Spatial Observation” is defined in the Observation & Measurement 2.0 specification (OGC 10-025) subclause 7.13 and can contain any gml:AbstractGeometry type, such as points, lines or polygons.
During the devlopment of the RESTful Binding Extension, a requirement arose for deleting single observations. To solve this, I developed the DeleteObservation extension oriented at the DeleteSensor operation.
You can delete only observations, that have a
gml:identifier element. The current implementation is available via the following bindings:
