Wikimedia European History Map over almost 2500 years

Andrew’s bloggage update: Created a video of some of the cool Wikimedia Atlas of European maps. Downloaded the images, rubber sheeted them and composited each map sheet in YouTube – if you squint you’ll see the four red dots I used as projection reference. This is a useful skill as crowd-sourcing emerges as a tool for good, be it for HOT Nepal maps for earthquake relief, or to geo-reference some of the million British Library maps.

FOSS4G-Europe : Mapping parties, workshops & keynotes

The second edition of the FOSS4G-Europe Conference will be held at Politecnico di Milano in Como, Italy, from July 15th to 17th, 2015. The Conference aims to bring together FOSS4G users and developers worldwide and foster closer interactions with and amongst European communities in order to share ideas for improving geodata, software and applications openess.

This week FOSS4G-Europe announced its Mapping parties, updated list of workshops and 2 new keynotes speakers.


1. Mapping Parties
Mapping Parties are FOSS4G events where people meet up for making and having fun.
They will take place in Como on Wednesday, July 15th.
In the true spirit of mapping parties ANYONE is welcome and can participate. The organized mapping parties are:
  • OpenStreetMap mapping party
  • Indoor mapping party
  • Land coverage validation game
  • Emotional mapping


2. Workshops
Seats still available for workshops and  here is a reminder for the programmed workshops:
  • Raster and vector processing with GDAL
  • How to write a Python GRASS GIS 7 addon
  • Analysis with QGIS
  • Land cover mapping with high resolution satellite images using Orfeo Toolbox, QGIS and OSM
  • R for spatial data
  • Free and open source software for kinematic GNSS positioning
  • Deploying Web Processing Services using ZOO-Project – Examples Python WPS using PgRouting
  • GeoServer on steroids: getting the best out of GeoServer
  • Geopaparazzi: never out of data in the field
  • FOSS4G routing with pgRouting, OpenStreetMap and OpenLayers 3
  • Spatio-temporal Big Data: the Rasdaman approach in the context of the PublicaMundi project
  • SensorWeb and IoT with OpenSensorHub

3. Keynotes

Here ar the two new keynotes speakers: 

– Jeff McKenna, President, OSGEO Foundation

– Jun Chen, President, International Society of Photogrammetry and Remote Sensing

As a reminder here are the previously announced:

Alessandro Annoni, Head of Digital Earth and Reference Data Unit, European Commission’s Joint Research Center
Georg Gartner, President, International Cartographic Association
Patrick Hogan, NASA World Wind Project Manager, NASA
Ki Joune Li, Professor,  Pusan National University

OpenLayers 3.5.0 Released

The popular open source web mapping library OpenLayers 3.5.0 has been released.

Some of the new features according to the official blog: “Among the features in this release is a new snapping interaction. This can be used in conjunction with the draw and modify interactions to allow vector editing with snapping support. See the new snap example for a demonstration of its use. Adding to OpenLayers’ already excellent vector rendering and editing support, the Canvas renderer now supports a wrapX property on vector sources. Those in the mapping world have long known that the world is flat. But it is less common to accept that our flat world only has north and south edges while extending infinitely east and west. The wrapX property on vector sources (true by default) indicates that features will be rendered repeatedly as users pan east or west of the dateline. As if snapping and wrapping weren’t enough new vector functionality, the draw interaction now supports freehand drawing.  […] While we stand in allegiance with GeoJSON, you can now build support for Esri JSON into your applications. This adds to the already extensive feature format support of GeoJSON, GML, GPX, IGC, KML, Encoded Polyline, TopoJSON, and WKT.”

GeoNetwork OpenSource 3.0.0 Released

The popular geographic metadata catalog software GeoNetwork OpenSource just released version 3.0.0.

A reminder of what it is: “GeoNetwork is a catalog application to manage spatially referenced resources. It provides powerful metadata editing and search functions as well as an interactive web map viewer. It is currently used in numerous Spatial Data Infrastructure initiatives across the world.” Amongst the long list of new features:
