short announcement: learn to map with cartoDB

Dear folks, most of you probably know how to map things using software on your pc. Some of you might also know cartoDB. We like their service as our job-page here on is based on their tables, API and GeoJSON export functionalities. Additionally it’s for free (with some limitations)… The guys from CartoDB now offer an online learning event which will give newbies the chance to map their data in a very interesting online mapping engine.

The Spiegel Magazine and their “maps”

Today I stumbled upon a “map” on Spiegel Online ( an import news page in Germany ) which shows the spied countries of the NSA.

In a recent post I’ve described a way to geocode in a Google Spreadsheet quite easily. Now let’s move a little bit away from this crazy web 2.0 stuff and get a little bit more desktop orientated: Let us geocode addresses directly in LibreOffice (and OpenOffice probably as well). We will do this using the googlemaps API. If you are really into open stuff we show OSM geocoding as well.

In this tutorial I’ll document a working example on consuming this layer with leaflet. But first we will start with the easy part of creating the table in cartoDB.
