I’ll be heading to Seattle, Washington this morning for the State of the Map Conference! My flight to Seattle-Tacoma International Airport will be one of the roughly 380,000 aircraft movements that take place at the facility each year and I will be one of roughly 42 millions passengers that travel through the airport annually. The facility also contains a 13,000-car parking garage, the largest structure of its kind in North America, which is visible at the top of this Overview.
