Separated data graphs

In order for our site data to be turned into a soundscape the data on the graphs needed to be separated into each of its area components. This allowed the information on the graphs to be read more easily and therefore converted into sound. This post is to show these separated graphs so that you, the reader, can also get a better idea of what the data is showing. Firstly, below is an image showing how the site has been split up into the separate areas which the data is based on:

By separating the site up in this way the data could be collected for each part allowing the frequency of people in the area over time to be studied more specifically. The graph in the previous post shows the data for all of these areas together. However to be able to model the data the information had to be separated back out into the individual squares as above. The graphs that were produced are shown below:

The aim now is to use these graphs to change the data into a soundscape. The peaks and troughs of these graphs will be used to define different elements of the sounds, for example the pitch may be high on a peak then drop to a low pitch in a trough. The general outline of these graphs will also make this easier as more generalised curves can be produced from these to highlight key areas of change. This can then be used to make the soundscape.
