The data was provided by the aircraft noise abatement office [(http://www.flyquietsfo.com/)](http://www.flyquietsfo.com/) of San Francisco International Airport.\r\nThe data cover Jan-Mar 2006. It is organized by day and flight. Each record contains some information about the flight and a sequence of 3D position and estimated speed.\r\n\r\n\r\nThis data contains thousands of trajectories that can be used for trajectory clustering. The data is used by the Aircraft Noise Abatement Office\r\nto analyze the trajectories of aircraft flying in and out SFO. The objective is to minimize the noise pollution due to aircraft in the San Francisco Bay Area\r\n\r\nThe files have the extension \"lt6\" and are organized as follow, one file per day.\r\n\r\nline number & explaination\r\n\r\n<pre>1 TRACK OPNUM (TRACK header word and operation number)\r\n2 eventid (Corralation number)\r\n3 trackstart date (in time since 1900, A8 version four year digit)\r\n4 trackstart time HH:MM:SS\r\n\r\n\r\n5 trackend time HH:MM:SS\r\n6 airportid\r\n7 ACID (FLIGHTNUM/TAILNUMBER)\r\n8 owner name\r\n9 aircrafttype\r\n10 aircraft category\r\n11 beacon\r\n12 adflag\r\n13 waypoint\r\n14 other_port (dest/origin)\r\n15 runwayname\r\n\r\n\r\n16 min alt\r\n17 max alt\r\n18 min range\r\n19 max range\r\n20 Count of trackpoints (to follow)\r\n21 x,y,z,v,t (all points is meters relative to MRP, velocity and time from start of track)</pre>", "distribution": [{"@type": "dcat:Distribution", "description": "Part 1", "downloadURL": "https://c3.nasa.gov/dashlink/static/media/dataset/SFO2006Q1-1.zip", "format": "ZIP", "mediaType": "application/zip", "title": "SFO2006Q1-1.zip"}, {"@type": "dcat:Distribution", "description": "Part 2", "downloadURL": "https://c3.nasa.gov/dashlink/static/media/dataset/SFO2006Q1-2.zip", "format": "ZIP", "mediaType": "application/zip", "title": "SFO2006Q1-2.zip"}, {"@type": "dcat:Distribution", "description": "Part 3", "downloadURL": "https://c3.nasa.gov/dashlink/static/media/dataset/SFO2006Q1-3.zip", "format": "ZIP", "mediaType": "application/zip", "title": "SFO2006Q1-3.zip"}, {"@type": "dcat:Distribution", "description": "Part 4", "downloadURL": "https://c3.nasa.gov/dashlink/static/media/dataset/SFO2006Q1-4.zip", "format": "ZIP", "mediaType": "application/zip", "title": "SFO2006Q1-4.zip"}, {"@type": "dcat:Distribution", "description": "part 5", "downloadURL": "https://c3.nasa.gov/dashlink/static/media/dataset/SFO2006Q1-5.zip", "format": "ZIP", "mediaType": "application/zip", "title": "SFO2006Q1-5.zip"}], "identifier": "DASHLINK_132", "issued": "2010-09-10", "keyword": ["ames", "dashlink", "nasa"], "landingPage": "https://c3.nasa.gov/dashlink/resources/132/", "modified": "2025-03-31", "programCode": ["026:029"], "publisher": {"@type": "org:Organization", "name": "Dashlink"}, "title": "Flight tracks, Northern California TRACON"}
