Beginning nav processing.

PPP Result:

Lat 65 34 27.54619
Long -37 07 58.16001
Elevation 83.444

comment:3 Changed 6 years ago by stgo

There is a large data gap at the beginning of the nav file, processing from gps second 47150 gives a good result. This is way before the flightlines.

comment:4 Changed 6 years ago by stgo

Beginning hyperspectral and lidar processing.

comment:5 Changed 6 years ago by stgo

Lidar horizontal overlaps look good. Reprocessing hawk with bands 35 70 90 to get better SCT estimations.

comment:6 Changed 6 years ago by stgo

Lidar lines with reduced returns:

Beginning rcd processing. Hyperspectral is delayed by line 6 until processing issue is resolved.

comment:9 Changed 6 years ago by stgo

There are large number of photos that have been placed in the nogps folder, these will be mentioned in the readme.

comment:10 Changed 6 years ago by stgo

Waiting on basestation data before proceeding.

comment:11 Changed 6 years ago by stgo

Reprocessing nav with new basestation. PPP result is good:

Lat 66 24 02.38088
Long -38 12 50.55401
Height 421.261

comment:12 Changed 6 years ago by knpa

Started RCD delivery check, however there are only 38 photos in the readme, and over 600 in the photographs dir, most of them incorrectly named so looks like something is wrong. stgo to go back and look at it.

Recreated RCD delivery, this time files are named correctly, readme looks better as well.

comment:15 Changed 6 years ago by tipo

Pitch error visible on lines 11 onwards.

comment:16 Changed 6 years ago by tipo

Hyperspectral delivery checked, no problems found.

comment:17 Changed 6 years ago by knpa

Beginning RCD delivery check.

comment:18 Changed 6 years ago by stgo

Fixed pitch error with value -0.003041469. Will recreate lidar with new files.

comment:19 Changed 6 years ago by knpa

Completed RCD check - still some problems:

  • I would change the NOT gps tagged files to be "all files failed to be gps tagged except:" as this will be a much shorter list by the looks of it. Also explain that these are the only ones that will appear in the flightline photos below
  • should also say why not gps tagged i.e. there was log information missing (I'm assuming they were missing from the eventfile)
  • not GPS tagged list goes up to 337 but there are only 336 images
  • The exiftool dump example in the ReadMe should be for one the images that has been fully tagged
  • The first photograph is messed up - don't deliver

comment:20 Changed 6 years ago by tipo

LiDAR line 10 has everything at the top of a cliff classified as noise.

comment:21 Changed 6 years ago by stgo

Recreated camera delivery with corrections, the images did not have GPS data available in the event log. I've also fixed the KML file, which still had images added with lat/long 0,0.

comment:22 Changed 6 years ago by tipo

Checked LiDAR delivery, no problems found.

comment:23 Changed 6 years ago by stgo

Corrected RCD, starting dispatch.

All data dispatched 23/10/2013.
