MESO is a realtime, ultra-high definition video installation. It randomly cycles through thousands of images of digital landscape data covering the majority of North America. Each image is a direct translation of digital elevation data into map form, where white represents the highest surface elevation in the area, and black the lowest. No other information is included or implied. In removing all of the usual context from these images of the Earth’s landscape, we reveal patterns and forms inherent in the land, but normally hidden from view.
The title “MESO” stands for “meso-scale”, or “in between scales.” The data in this work are in between two scales that viewers find familiar: the global scale, such as the shapes of continents and nations; and the local, micro-scale, such as a person’s town or neighborhood. The time scales involved their formation, as well, are short compared to global tectonics, but long compared to landslides and construction. The middle scales had been too far removed and too many in number to be part of a common language of landscape. But the recent technological emergence of powerful sensors, supercomputers, large-scale data storage, and global networking finally allows exploration of these meso-scales, not just in geomorphology, but in all areas of science. This work aims to methodically reveal the myriad shapes and patterns of the Earth’s surface at these intermediate scales.
This work uses 1-arcsecond digital elevation data from the US Geologic Survey, processed by the open-source packages GDAL and NetPBM and the artist’s own scripts.
Media Used: Digital video.
Mark J. Stock is an artist, scientist, and programmer who creates still and moving images and sculpture combining elements of nature, physics, chaos, computation, and algorithm. His work explores the tension between the natural world and its simulated counterpart, between organic and inorganic, digital and analog, and structure and fluid. Mark eschews the ‘black box’ nature of commercial software— his work is created with scientifically-accurate research software, mostly of his own design.
Stock has been in over 80 curated and juried exhibitions since 2000, including Ars Electronica, ASPECT Magazine, and SIGGRAPH. He has spoken at numerous scientific, graphics, and art conferences and workshops, and has published papers in a variety of fields. Mark completed his Ph.D. in Aerospace Engineering at the University of Michigan in 2006, supports scientific visualization efforts at NREL in Colorado, and creates artwork in his studio in Somerville, Massachusetts.
