Pushpin allows us to leverage that investment by identifying changes in parcels without costly on-site inspections.

As part of its continuing efforts to increase office efficiency, the Lee County property appraiser's office has partnered with Pushpin, a Minneapolis-based technology company. Using machine learning to analyze multiple years of aerial photography, Pushpin determines what kinds of changes, if any, have been made to county parcels and provides that data in an intuitive way to office staff for analysis.

"We fly new aerial photographs of Lee County every year to help with our parcel inspection and valuation process," said Kenneth M. Wilkinson, Lee County Property Appraiser. "Pushpin allows us to leverage that investment by identifying changes in parcels without costly on-site inspections."

With over 540,000 vacant and improved real property parcels to inspect, change detection technology allows the office to focus its efforts in a more effective manner.

"Having a full accounting of new construction, additions and demolitions is important in developing a fair and equitable tax roll for everyone," continued Mr. Wilkinson. "Pushpin is a great new tool we plan on utilizing to increase the accuracy of our data collection process."
