We’ve just updated the MapTube website with a new release of the software that makes all of the Census maps clickable. Anything tagged with the “CENSUS2001″ keyword is clickable, as well as most of the maps made from the data on the London DataStore.

The new clickable map icon. This is used to turn the clickable maps feature on or off.

The resulting popup window showing attribute data for the feature that has been clicked.

The maps page now contains an additional button below the zoom level slider which shows a representation of a mouse. If this is enabled, as shown below, then a single mouse click on the map will display a popup window containing more information about the feature just as in a traditional GIS.

The image on the right shows the default popup window which just lists the attributes from the CSV file used to make the map. If you want to examine the data, there is a link to download the CSV file from the ‘more information’ page.

The html in the popup window is obtained by applying a transformation to the attribute data that turns it into the html that you see displayed in the window. In the next release of MapTube we will include a user interface to allow people to build maps of fixed geometry data (i.e. census data, ward codes, districts, countries etc) directly from data in a CSV file. We are also planning to add a web based interface to allow people to write what appears in the popup window themselves so that it will be possible to include graphs and charts.
