CARI Basestation not used.

Processed the GPS time from 388920.000 till 393600.000
Set the elevation mask to 13.5 degrees to achieve the best possible results with an L2C phase correction of 0.25 cycles.

There is a spike in the latitude seperation which goes above a seperation of 0.1m this spike could affect upto the first 10 seconds of flightline number 8.

Beginning LiDAR Delivery Check

comment:17 Changed 4 years ago by dap

LiDAR Delivery Check

Complete. Found the following minor problems:

  • Weather notes, altitude and speed not present on typed up logsheet
  • PI has not been emailed about vectors yet - ask before data are sent.
  • Both documents in doc/ are named wrong - I've renamed these.
  • sup file does not need to be delivered - I've removed this.
  • incase in "Data details" section is two words.
  • Data quality remarks - be more specific (say which flightline has the hole) and, if you know why it has the hole, say why and what this means. Instead of "There is cloud at the end of most flight lines.", I would write something more detailed like "This dataset was severely affected by cloud coverage. This has been classified as noise (classification 7)."
  • Dan's surname is spelt wrong in the readme, page 11 ("Clewly" should be "Clewley").
  • Discrete ASCII flightlines should have CRLF line terminators
  • Too much foliage has been classified as noise. This will need to be classified to classification 1 before the data are sent. Will then need to re-sort the LAS files using lassort, convert them to ascii and copy the classification over to the las1.3 files.

Dataset will need to be rechecked when the LAS files have been reclassified.

Disregarding stuff about weather notes, logsheet is fine. Data quality says the first flightline has the hole, that is sufficient.

LiDAR Delivery Check

  • Pre-vector email still needs to be sent to PI - ensure this is done before delivery of data.
  • Typos still existed in read me document with Dan's surname and the word "incase" - I have fixed these.
  • Have also removed knpa from the contact details section in read me (not a problem in first quality check as he was still at PML at this point).
  • las1.0/ was incorrectly named - have renamed this to las1.2.
  • ascii las file line endings needed to be converted to CRLF line terminators - I've done this using unix2dos * in ascii directory.

Full waveform data has not yet been checked - waiting for Windows machine to become free.

LiDAR Delivery Check

laszip completed, created 9 wdz files and 9 laz files, as expected. Will check las 1.3 files in Wave Viewer when Windows machine becomes available.

LiDAR Delivery Check

Checked files in Wave Viewer. The following records don't have waveforms:

  • File 01: the first ~10,000
  • File 02: the first ~11,000
  • File 04: the first ~50,000
  • File 07: the first ~45,000
  • File 08: the first ~16,000

comment:23 Changed 4 years ago by tec

So the delivery is ok?

comment:24 Changed 4 years ago by dap

LiDAR Delivery Check

Spoken to mark1 regarding the missing waveforms, this is a known issue. Data at
BGS12_01-163c-lidar-20140926 is therefore ready to be delivered.
