Navigation Data

Navigation files were extracted as a comma-delimited American Standard Code for Information Interchange (ASCII) text file from a Garmin GPSMAP 696 receiver. For each trackpoint, the Garmin GPSMAP 696 recorded the following: date, time, latitude, longitude, altitude, and color (for aviation graphics).

The images were acquired using a Nikon D810 digital camera. The camera was synchronized to Coordinated Universal Time (UTC) and the time of capture was recorded in the Exchangeable Image File (EXIF) header of each image. Image files were named according to the year, month, day, and time they were captured. The image filenames have the format yyyy_mmdd_hhmmssd.jpg. (For example, image 2016_0308_133636d.jpg was taken March 8, 2016, at 13:36:36 UTC, while "d" indicates that a digital camera was used.) Images are associated with GPS positions according to the time of capture. Google Earth is used to view selected images taken during the flight based on their time of capture compared using the recorded position of the aircraft from the GPS record.

The processed navigation file can be accessed from within the nav folder or by clicking the following link to the comma-separated value (CSV) file: ds1030_2016-316-FA-B.csv. The file contains 12 fields that are defined as follows:

Raw Navigation

The raw navigation files can be accessed from within the nav folder or by clicking the following link to the text file (TXT): ds1030_2016-316-FA_0308_gpsmap696.txt (text file). The file contains six fields (separated by tabs) that are defined as follows:

Field 1: HEADER: "T"
Field 2: DATE: (mm/dd/yyyy)
Field 3: TIME: Date and Time (hh:mm:ss am/pm)
Field 4: LATITUDE: latitude (decimal degree, position of aircraft)
Field 5: LONGITUDE: longitude (decimal degree, position of aircraft)
Field 6: ALTITUDE: (feet)
