The Green Spaces consultation required citizens to identify any green space – whether a roadside verge or country park – by drawing the extent on a map, supplying a name, classifying it, and providing comments. We designed an Open-Layers based webpage to do this (available at http://www.lsr- online.org/greenspaces/). It attracted 1110 ‘online’ responses during the consultation period be- tween January and April in 2011.
An spatial overview of responses is provided by superimposing the extents of identified green spaces as semi-transparent polygons, achieving our goal of using colour opacity to show which parts of Leicestershire have valued green space. A disadvantage is that green spaces with the largest extents have greatest visual salience at the expense of overlapping small areas. We address this by superimposing semi-transparent boundaries over the top to show where these are.
Moving the mouse over the map, barchart or text box (after typing a keyword) highlights associated green spaces in green on the map and in the barchart bars (as in ‘who’). The number of highlighted spaces is shown in the yellow area (bottom right).
Access to individual records is achieved by left/right-clicking to cy- cle forwards/backwards through the currently selected set.
