I wonder how accurate the locations are in this LiDAR dataset and/or the Queens Giant Wikipedia article. The Alley Pond Park candidate looks suspiciously close to the the Queens Giant, so I wonder if it's actually picking the same tree?

The (typically government) agencies that pay for these scans create specifications for the data to meet. This is not hard to find. IIRC the accuracy is generally less than 0.1m (though the precision is usually 0.01 meters or feet).
