The twitter activity varies over the course of the day as shown in an earlier post on Tweet Times. So far we were using the timeRose to visualise the temporal activity.
The data used here is based on the geo located tweets collected for the New City Landscape maps of New York, Paris, London and Munich. I have now produced a simple contour for each hour of the day. This shows the activity over the period of 24 hours, with all days superimposed. This visualisation only looks at the data collected for Munich. The detailed New City Landscape map of Munich can be found HERE. In Munich there are some hotspots that are constantly active over the course of the day, like the airport terminals in the top right hand corner and of course the centre. Then there is a lot of fluctuation around the center and ocasional spots on the outskirts. For orientation purpose I have put in major green features and the water line.
