Rainer Albert is an experienced Surfer user and recently discovered the versatility of Voxler. Below outlines his contribution to the modeling of the Kölliken hazardous waste landfill using 3D visualizations from both Surfer and Voxler.
The landfill consists of a wide range of organic and inorganic wastes from the industry, commerce and public sectors. Over a 7 year span 475,000 tons of hazardous wastes were deposited in the landfill. The site’s restoration process started in 1985 and the site is currently being excavated and remediated under the large hall (as pictured above) in order to be fully restored by 2016.
Rainer uses Surfer to display the topography of the site along with the 3D rendering of buildings. The image below shows a 3D surface map with an overlaid contour map, post map and image. The building in the forefront is the Swalba and House Matter Hall.

Voxler is used to display the waste type and waste concentration from data collected between the surface and bottom layers. The distances between the surface and bottom can span up to 17 meters apart. In the below Voxler image, the transparent surface layer is overlaid with contour lines to display the landfill’s terrain while also displaying the chemical types and concentrations below.
This image, created in Voxler, details the Kölliken hazardous waste landfill’s terrain along with chemical types and concentrations.
