Accurate Building Footprint Polygon Data
Accurate Building Footprint Polygon Data
The definitive spatial foundation for building world-class products and location intelligence
Precise Polygon Data for Better Location Accuracy
Understand the true shape of POIs and how places relate to each other using reliable geometry data.
Robust polygon geometry data includes:
- Place shapes as Well-Known Text (WKT)
- Spatial hierarchy between polygons
- Attributes for parking areas and polygon quality
Maintaining Your Own Database of Polygons Is Challenging
You need data you can trust and rely on. We apply complex engineering and human verification to ensure accuracy of all POIs in our datasets.
Power Precise Location Analytics with Telemetry Ready Polygons
Our precise polygons are built to be the foundation of your mobility analysis. By joining SafeGraph Geometry with telemetry data, you can move beyond simple ‘proximity’ and achieve true attribution – distinguishing a customer inside a store from a pedestrian on the sidewalk.
Our World Is Complex - We Make Analyzing It Easy
We give you metadata so you can easily distinguish the spatial hierarchy and relationship between different places. With clear polygon hierarchies that have parent-child relationships, you’ll gain detailed insights about the POIs you’re analyzing.

FAQ’s
1. What is building footprint polygon data?
Building footprint polygon data represents the actual shape and boundaries of a place. Instead of a single coordinate, it maps the full area a location occupies. This helps you understand how places exist in real space and how they relate to nearby locations.
2. How is polygon data different from point-based location data?
Point data uses one latitude and longitude to represent a place, which can miss the true boundaries. Polygon data captures the full geometry, making it easier to analyze proximity, overlaps, and spatial relationships, especially in dense areas.
3. What does the geometry dataset include?
The dataset includes polygons in Well-Known Text (WKT) format along with useful metadata. This covers spatial hierarchies between places, attributes for parking areas, and indicators that help you assess polygon quality and reliability.
4. How does polygon data improve visit attribution?
By using precise boundaries, polygon data helps determine whether a device is actually inside a location rather than just nearby. This improves the accuracy of visit attribution and reduces confusion between closely located places.
5. Why is it difficult to maintain polygon data internally?
Building a reliable polygon dataset requires constant updates, data cleaning, and validation. Real-world locations change often, and maintaining accuracy at scale demands both engineering effort and ongoing quality checks.
