FOSS4G 2013: Old Maps Online and Georeferencer


OSGeo's Global Conference for Open Source Geospatial Software that brings together developers of map applications from all around the world. This year the conference took place in Nottingham in the UK 17th - 21st September and Klokan Technologies was there.

You can find conference's website at:  http://2013.foss4g.org/ and all presentations are available in the slideshow on YouTube: http://www.youtube.com/playlist?list=PLWW0CjV-TafaBjkroiOxcQw8NdOQ_fhu2 Anyone interested has a possibility to view the presentations from the record.

Probably the most interesting are the technical presentations about the new OpenLayers3, which is the project on which we participated and which will be used in the new version Georeferencer and StareMapy.cz.

Technical details of our work on Georeferencer and MapRank Search presented Vaclav Klusak. Afterwards, Petr Pridal spoke about the new open-source project TileServer and accessing map tiles using standard OGC WMTS.

WebGL accelerated Georeferencer presented on ICA conference in Rome


On ICA conference in Rome (19-20 Sep. 2013) Hynek Pridal from Klokan Technologies presented integration of Polynomial and Thin plate spline transformation into Georeferencer. Those are more accurate for some of the use cases. Up to now this was done only with special map server software with OGC WMS needing installation on the local server. Now it is possible using html technologies such as .HTML5 Canvas, SVG or WebGL which means no installation on your server and no troubles consequently.

WebGL allows hardware accelerated graphical operations on a web page. A graphic card of your own computer is utilized and therefore the overall performance is much higher then experienced ever before. Maps appears faster and there is no need to store georeferenced and non-georeferenced copies of the maps separately - so it is possible to save on the digital storage as well.
