First three Data Crystals

My first three Data Crystals are finished! I “mined” these from the San Francisco Open Data portal. My custom software culls through the data and clusters it into a 3D-printable form.

Each one involves different clustering algorithms. All of these start with geo-located data (x,y) with either time/space on the z-axis.

Here they are! And I’d love to do more (though a lot of work was involved)

Incidents of Crime
This shows the crime incidents in San Francisco over a 3-month period with over 35,000 data points (the crystal took about 5 hours to “mine”).  Each incident is single cube. Less series crimes such as drug possession are represented as small cubes and more severe a crimes such as kidnapping are larger ones. It turns out that crime happens everywhere, which is why this is a densely-packed shape.

Construction Permits
This shows current the development pipeline — the construction permits in San Francisco. Work that affects just a single unit are smaller cubes and larger cubes correspond the larger developments. The upper left side of the crystal is the south side of the city — there is a lot of activity in the Mission and Excelsior districts, as you would expect. The arm on the upper right is West Portal.  The nose towards the bottom is some skyscraper construction downtown.

Civic Art Collection
This Data Crystal is generated from the San Francisco Civic Art Collection. Each cube is the same size, since it doesn’t feel right to make one art piece larger than another. The high top is City Hall, and the part extending below is some of the spaces downtown. The tail on the end is the artwork at San Francisco Airport.
