Realeflow + Mapbox — Geospatial Polygon Visualizations for Real Estate Investors

A few months back, our team at Realeflow decided to embark on an ambitious journey to combine geospatial polygons, i.e. the shape of a real estate parcel, with our nationwide lead data. For anyone who has worked with real estate data, you will know this is no small feat.

Value Provided

If this is your first time hearing about Realeflow, we are a SaaS company that provides a CRM + other investing tools to residential & commercial real estate investors. Our Leadpipes tool allows investors to search with a myriad of different filters to create a lead list. Typically those investors will then either send out a direct mail campaign, use the list for targeted PPC marketing, or use some other marketing technique to get in touch with the owner of the property.

Mapbox Studio. Such an awesome tool. Seriously.

The Process

In order to accomplish this, there were a few things that really had to work well together:

  1. Create a GeoJSON file that includes all of the polygon + data features that we wanted to display. This has to be updated daily.
  2. Create an MBTile (Mapbox format, essentially SQLite) using the Mapbox tippecanoe library to dramatically reduce the GeoJSON file size, enabling us to show a nationwide visualization.
  3. Create visualization layers using Mapbox studio and implement them on top of our existing Leadpipes tool.

The Future

While we’re very excited about what we’ve released so far, this is only V1. In addition to adding more data, improving the UX with user feedback, and making the tools more mobile friendly, I’m also able to announce two new features that we’ll be adding in the next month or two. It’s probably easier to show the proof of concept as opposed to trying to describe them.

Parcel height corresponds to data e.g. last sale price

Time Slider

Parcel visibility is driven by event date e.g. last sale date
