Building Footprint Geocoding – A Football Field’s Difference in Accuracy

100 yards more accurate, 12 percent of the time. Would your business benefit from moving a geocoded location 100 yards closer to the real location? What does a football field closer mean to you? We recently showed two companies – a Fortune 500 company and their fast-moving startup client – what rooftop-accurate geocoding looks like. The result? Geocoding to addressed building footprint data significantly improves their geocoded customer locations resulting in more accurate business decisions.

These companies gave us the chance to improve upon the geocoding accuracy they were getting from their current provider. Their database – geocoded with an industry leading geocoding solution – contained their commercial customer listings. We matched their address information against our addressed building footprint data. From there it’s easy to see how we improved their existing geocoded locations – a quick check of our location against the previous location.

We matched 500,000 records in their database against our nationwide building footprint database. Over 60,000 records showed a new location over 100 yards from the original location. We checked record after record, and we struggled to find examples where our new, more accurate location didn’t represent a material improvement in accuracy. These companies appreciated the improved geocoding; their business rests on a foundation of accuracy.

Results with Accuracy

One of the commercial properties in the database is 27001 US Highway 19 N, Clearwater, FL – a mid-size shopping mall. How do we improve the accuracy of the address? We take a location that previously geocoded to parking lot accuracy with the leading geocoding provider, and we move that geocoded location into the building.

This improved accuracy for the new point is meaningful for your subsequent analysis. In addition, you could stop using points for analysis and start using the building footprint polygon. For example, if you are an insurance company you can stop using a point for flood risk determination and start using the whole building polygon to test against a peril zone such as flood. If you are a location based marketing company you previously were buffering points to come up with geofence areas; you can now geofence the building footprint polygon.

In another example, let’s geocode 868 Bayway Blvd, Clearwater Beach, Florida. You are doing a critical test to understand exposure to peril based on coastline proximity. Using your existing geocoding technology you could geocode to street level accuracy (red point), or a slightly more accurate address point (yellow). You may have believed this is the best accuracy possible for your peril and coastline-related spatial tests. Connect addresses to addressed building footprints and you will get a better point location (green point) and a building polygon (green region) that you can use in your decision making. This dramatic increase in accuracy decreases your risk and increases your profit.

High Accuracy geocoding is now 80% data, 20% software

Geocoding will always be one part software, one part data. When comparing the different geocoding solutions available today, it is very clear that data makes or breaks the accuracy of a geocoding solution.

If Data makes or breaks the quality, accuracy and results of a geocoder, then the most capable data must be used to ensure individual location precision and certainty. At BuildingFootprintUSA™ we create addressed building footprint data that can be used in any geocoding, reverse geocoding, and location technology, to support any industry. As we have shown you above, this addressed building footprint data is the next generation of accuracy, exceeding the results from street and address point geocoding.
