How it works

Step 1: collect, clean, and geocode data

We begin by collecting raw datasets from a variety of sources such as Socrata, Yelp, and the National Parks Service.

Individual datasets can be visualized on a map as shown to the right (below, on mobile), but plotting multiple maps at once doesn't yield much visual insight.

Step 2: approximate the density of each dataset

Rather than plotting all of the points in a dataset, we can visualize each dataset's density using a technique known as kernel density estimation.

Step 3: combine weighted density estimates

When a user enters their preferences and clicks 'submit', the server computes the sum of the weighted density maps and returns latitude and longitude coordinates corresponding to areas with the highest overall density.

What's next?

We're working on applying unsupervised machine learning algorithms, such as K-means clustering, in order to uncover hidden neighborhood dynamics and relationships. Check out this page to see some of the progress we've made.
