NGA Arducopter Metadata Format - VisionSystemsInc/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
```
