Invalid Data is a new project, part of my ongoing collaboration with the Digital Earth Australia platform and Geoscience Australia – and most recently, selected for exhibition in the Alane Fineman New Photography Award at the Ballarat International Foto Biennale, one of Australia’s largest festivals of photographic arts. This project involves a critical engagement with the cloud-filtering algorithms employed by Geoscience Australia’s “Digital Earth Australia” (DEA) platform.
Geoscience Australia developed DEA as a “data cube” which stacks 40 years of Australian satellite data into a database form that is accessible using a range of GIS applications and programming environments.
Scientists at DEA use satellite data to track environmental change over time, assessing vegetation health and the presence of water on the land. In order to track these changes however, they must filter clouds and cloud shadow from the data in order to obtain a clear picture of the land, and they employ complex algorithms to identify and excise this atmospheric noise. The result of this filtering is a huge and constantly growing archive of “invalid data” – which is in fact a multi-year record of the incredible cloud formations that daily spread across the continent.
Production of these images involved working creatively with the structures and capacities of the DEA platform, and in particular, with the Fmask and ACCA algorithms used in DEA to mask clouds and cloud shadow. These images invert normal geoscientific process, filtering out the land and focusing on the cloud data that is usually filtered from the archive. In choosing to focus on the clouds and algorithmically filter everything else, this project inverts the figure/ground relationship employed in satellite imaging, bringing what is normally deemed redundant into focus.
in a continuation and recontextualisation of this project, Invalid Data: W.E.S.T. is a collaboration between myself and the experimental improvising trio W.E.S.T. ; a multi-channel audiovisual installation that explores the confluences of image and sound, art and science.
Wilcox, Encarnacao Swanton Trio (W.E.S.T.) comprises three composer-performers individually renowned for their work in jazz, improvisation, indie pop, art music and soundtracks: Felicity Wilcox (piano), John Encarnacao (guitar) and Lloyd Swanton (bass). W.E.S.T. improvise using their instruments in conventional and unusual ways; objects are interfaces for performance, activating the entire apparatus of their instruments. These experimental techniques and the resulting sonic textures form the basis of W.E.S.T.’s musically and visually intriguing performances.
In Invalid Data: W.E.S.T. I am building on my previous work exploring satellite data through images derived from creative investigation of the cloud-filtering algorithms of Geoscience Australia’s “Digital Earth Australia” platform. In this project, I intercut treated satellite images of clouds with in-depth multi-camera footage of W.E.S.T. captured during improvisation, translating the language of live event coverage and music video into a multi-screen presentation of long-form musical improvisation. The resulting audiovisual meditation is surprising and moving in equal measure, and draws parallels between spontaneous artistic processes, collaborative creation, and the forces that shape the Earth.
