Invitation to new PyWPS development

Sunday, May 12th, 2013

It has been a while, since we've touched code base of PyWPS properly. We were focused on fixing of reported issues, which were usually not that big. For most people it seemed, that PyWPS was just working silently somewhere at the server and doing it's job. But time has moved and ...

OGC a návrh nového standardu Geoservices REST API

Friday, May 10th, 2013

Jenom krátká poznámka o tom, kterak se v komunitě poněkud zvedla vlna odporu proti způsobu a formě, s jakou OGC schvaluje nový standard Geoservices REST API. Nejživěji probíhala diskuze asi na OSGeo discuss mailing listu a vyústila v otevřený dopis, podepsaný členy OSGeo (podotýkám, že OSGeo Board k tomuto tématu vydává ...

Pořadí os souřadnicových systémů v WFS

Sunday, March 31st, 2013

Tento text je překladem WFS – Achsenreihenfolge von Koordinatensystemen, jehož autorem je Jürgen Weichand Standard WFS sám o sobě žádné souřadnicové systémy nedefinuje. Souřadnicové systémy jsou registrovány ve speciálních registrech a v rámci WFS je na ně pouze odkazováno. Nejčastěji se odkazuje na registr EPSG. Ve verzi standardu WFS 1.1 a ...

INSPIRE view services – why it sucks

Yah, several years, we know about INSPIRE principals. Where ever I was going, I was telling people, how great the life is gonna be: everybody will share the data on the same basis - holy Web Mapping Service 1.3.0 will work literally everywhere. There is common and agreed set of ...

RSS versus sociální sítě – geopohled

Monday, March 18th, 2013

Že Google vypíná Reader asi víte - je toho plný - i český - internet. Reader používám už dlouho. Rozhraní měl podobné mému oblíbenému desktopovému liferea. Důraz Reader kladl na obsah (nebo to tak šlo alespoň nastavit): titulek, perex, článek (pokud to ten kanál podporoval), nikoliv formu (maximálně identifikační ikony ...

MapServer as WFS 1.1.0 client: Not suitable

Wednesday, March 21st, 2012

Last weeks I was playing with MapServer and it's support for WFS 1.1.0 client. MapServer is great peace of software, which does everything I ever needed. However, it looks like WFS 1.1.0 client implementation is at the edge of interest of the MapServer developers. Conclusion for MapServer, acting as WFS ...

Thursday, February 9th, 2012

Last months, I'm working on Proxy4OWS project, which is Python script, converting automatically WFS and WCS services into WMS. In such way, we are able use our WMS client for display list of "layers" to the user and we are also able to display those layers in the web browser. Problem ...
