Recently, I’ve been experimenting with\u00a0some Twitter-oriented hacks together with my friend Tom<\/a>. A very preliminary result of these activities is what I call the #SwissGIS map.<\/p>\n

Some, just a little, history: Over the last few years,\u00a0I have been collecting Switzerland-based Twitter users\u00a0that talk about topics around GIS, cartography, webmapping\u00a0and\u00a0geomatics on a list called SwissGIS. Find it at\u00a0https:\/\/twitter.com\/rastrau\/lists\/swissgis<\/a>, if you are interested in GIS-related news from Switzerland. The list is quite diverse in several respects: for one, it features GIS users, developers, OSMers, cartography\u00a0specialists and other groups. Given we’re talking of Switzerland it is also multilingual, with English, German and French making up the bulk of tweets.<\/p>\n

The internal network of users on the #SwissGIS list, as of February 2013<\/figcaption><\/figure>\n

I’ve visualised the #SwissGIS list before\u00a0on the Ernst Basler + Partners geoinformatics blog<\/a>. There are also re-publications in French<\/a>\u00a0and Italian<\/a>.<\/p>\n

This time, we went for a more spatial representation of #SwissGIS users. By now, the list features 167 members, more than 100 more than when the above visualisation was made. Click through for the interactive version<\/a>:<\/p>\n

\"\"<\/a><\/p>\n

The process for creating this map was as follows: Using the Twitter API<\/a>, we acquired data on all#SwissGIS members (with public accounts), extracted the\u00a0profile location (if it was stated by the user),\u00a0geocoded that information (if possible) and put it on a map with the user’s profile icon.<\/p>\n

The heavy lifting was done in Python with Mike Verdone’s Twitter API wrapper<\/a>. The map is built using the\u00a0versatile Leaflet<\/a> library and features OpenStreetMap<\/a> tiles styled and served by Mapbox<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"
