DEM data and satellite imagery pixel values to topographic chocolate

Our Project

Students at the Harvard Graduate School of Design and Harvard College present:

ChocoTopo; topographic 3D-chocolate, flavored to reflect the environment they depict and modeled from elevation values and pixel density.

Model 1: DEM to Chocolate

Technologies: QGIS, AccuTrans 3D, Autodesk Fusion360, and Blender

Elevation model data was downloaded from data repository freely available on the United States Geological Survey (USGS) website for Mt. Rainier (located in Washington state). This data was then converted to a USGS 1 Degree by 1 Degree DEM, converted to a 3D mesh, and then developed into a mold to use for the chocolate molding and melding process.

Model 2: Satellite Imagery Pixel Values as Elevation

Technologies: Grasshopper, Autodesk Fusion360

Satellite image of an urban condition near Mount Rainier is sampled in Grasshopper and converted to a low-poly mesh.
