//Re-Mapping Texture and Density of Dungeness

//It can be seen that the density, texture and composition of the shingle changes seemingly at random across Dungeness. I had intended to scan the variations of shingle to determine look for patterns, relationships and (in)consistencies which occur, the results of the 123D style scanning can be seen in another post. When scanning the shingle you only examine the top layer, something that has been my key focus in early research, but visiting the site suggests that the shingle has a depth of up to 35m. The density changes are revealed as you explore the landscape, both audibly and in the energy exerted in the walking as a the ground moves below your feet.

 

//I decided that, as well as visually identifying changes, a recording of my walk would reveal the sound variations between fine, medium, heavy, and mixed shingle deposits. Sampling of the audio files reveals a significant variation in sound between the 2KHz and 8KHz frequency range as I walk across changing ground. Time is mapped in the X, Frequency in the Y, and Amplitude in the Z. The resultant waves of the 10 second sample reveal my walking pace as well as the noise of the shifting shingle beneath. The longer shifting sound made under foot (loose shingle) has a lower amplitude and the sharper peaks the sudden clicking of larger rocks clattering together.

 

//the result is a secondary landscape (final image) which reveals the texture of the surface as well as the type of surface it is.
