NGA Arducopter Metadata Format - ngageoint/voxel-globe GitHub Wiki

The file format used for Arducopter datasets is based on the datasets we have received in 2014. The data set consists of the JPEG images, and a single GPS .txt file.

  • The JPEG images are those generated from the sensor platform.
    • The images will be sorted in Alphabetical order to make the final Image Collection used for processing.
  • The GPS file is a single txt file named “{Date} {time}_adj_tagged_images.txt” (with a space between {Date} and {time})
    • {Date} is “{year}-{month}-{day}”
    • {Time} is “{hour}-{minute}-{second}”
    • The files is a space delimited table file
      • The first line is a single header line

          image_id lon lat alt yaw roll pitch
        
      • Each additional line will be an entry associated with each image. The order will not matter.

      • Example line:

          1fps_image_0001.jpg -92.215759 37.648330 338.970000 96.520000 -2.500000 -0.170000
        
      • image_id - the basename of an image (not full or relative path)

          1fps_image_0001.jpg
        
      • lon - the longitude coordinate as a signed double in decimal degrees

          -92.215759
        
      • lat - the latitude coordinate as a signed double in decimal degrees

          37.648330 
        
      • alt - Altitude above the EGM96 Model, as a signed double in meters

          338.970000
        
      • yaw - Signed double in degrees

          96.520000 
        
      • roll - Signed double in degrees

          -2.500000
        
      • pitch - Signed double in degrees

          -0.170000
