Google Earth (finally) just added 3D imagery of Washington, DC. As a resident, I've long suspected some of the heights in the database were a bit off, but I didn't have sources to demonstrate it. I'm posting below some heights as measured in the Google Earth imagery, focusing on taller buildings without official heights in the database and buildings with a large discrepancy between database height and height in Google Earth. If the mods trust the existing source more, feel free to disregard any of these as "unofficial," but I think these numbers are pretty accurate.
