CityTracker

Every lot in New York City, on one map. Tap any lot for filings, permits, sales, and so much more. Or just ask: "How many permits were issued in Brooklyn last week?" There's so much public data in NYC, but it's hard to make sense of all of it. So we collect it in one place, make it fast, and fun. ASK IN YOUR OWN WORDS Ask that question, or any other, in your own words. The chat will give you an answer, and every source is cited and clickable, so you know how we got to the answer. SHOW MANY THINGS AT ONCE Right now, the map shows projects, filings, permits, and sales. You can select any of them, or all at once, and add filters and markers as needed. BASE MAPS AND LAYERS Many visual modes, many types of satellite imagery. Add historic districts or neighborhoods, and change the style, and that style persists for the next time. BUILDINGS COMING UP We can predict what buildings will exist soon, based on filings, so we show them on the map as 3D illustrations. That gives you an idea of how the city will look in the future.
