When implementing such a large operation as we are doing for the 3.8, there is inevitably functionality of the old code that has to be reevaluated. Mostly it is because you want something better, sometimes you have to remove some non performing functionality and sometimes you have to set priorities to determine what must be ported to the new structure and what will be dropped. This blog is about the losers of that judgment.
SenseBox and standardization recommendations for the Internet of Things
At the Internet of Things workshop of the OGC TC meeting in Brussels, we presented the SenseBox project which we are conducting together with the SWSL group at the Institute for Geoinformatics of the Uni Münster.
Besides demonstrating the SenseBox project, we gave recommendations for bringing the Internet (or better Web) of Things field together with the standardization efforts at OGC. Standardized REST APIs for things as well as well-defined JSON encodings for exchanging data about / from things could be an interesting contribution of the OGC to this emerging technology field. Similar suggestions were made by other particiapnts. E.g., Ben Pirt from the Internet of Things platform pachube announced their interest in OGC and standardized protocols for the Internet of Things.

SOS extension for GeoServices REST API based on ArcGIS Server
At the OGC TC meeting which took place this week in Brussels, our new SOS extension for the GeoServices REST API was presented. This extension, which is based on ArcGIS Server 10.1, embeds the functionality of a Sensor Observation Service (SOS) into the GeoServices REST API. The GeoServices REST API is currently making its way through the OGC standardization process.
The implementation of the SOS extension for the GeoServices REST API based on ArcGIS Server is developed for a project with the European Environment Agency (EEA). With the help of this software, the provision of Europe’s environmental data shall be facilitated – accessing data such as Ozone, noise, or water quality will become easier in future.
Please check the presentation held at the OGC TC meeting. The slides introduce to the project with EEA and the SOS extension.
Stacking rasters
It is always difficult when you have sets of different overlapping rasters to visualize properly. Rasters are usualy a full coverage and so two rasters(or more) on top of each other block the view on one of them. As historically ILWIS is oriented towards rasters I felt I had to offer more flexibility when displaying rasters. So what options do we have? Well basically three
- Transparency. Make one layer (partially) transparent so you can view the “lower” layer
- 3D Orientation. seperate the two layers in 3D space and view them there
- Time shift. Quickly blink between layers to inspect different layers
