Description

Data location: /users/rsg/arsf/arsf_data/2019/flight_data/italy/HyTES19-2019_169_Grosseto

Data arrived from Kings College London via hardisk on July 15 2019.

Scientific objective: Joint NASA and ESA campaign flying JPL’s HyTES thermal instrument over sites in Europe with a focus on crops and soil. Aim is to inform the future Land Surface Temperature Monitoring (LSTM) satellite mission. The NCEO Fenix instrument was flown alongside HyTES to provide visible – SWIR hyperspectral data.

PI: Martin Wooster

Sensors:

Fenix (requested, flown)

Navigation Processing
Basestation data converted to RINEX. Of the three RINEX files (which contain multiple days of data), a file for this date has been created with the following command:

teqc -st 2019_06_18:06:58:00.770 -e 2019_06_18:11:25:33.840 +nav Default_9488_1806_065800.19n Default_9488_0509_114526.m00 > Default_9488_1806_065800.19o

Navigation Processing
PPP processing in IPAS-TC hung at 57% of the reverse process step. Will return to processing this.

Navigation Processing
PPP processing completed using IPAS-TC. SOL file generated.

Possible FPS issues, requires other opinion

Fenix Processing
I reprocessed 3-band lines and found:

  • Flightlines 1, 13 & 14 look like there is a Frames per Second (FPS) error.
  • It is hard to initially tell if lines 7, 8, 10, 11, 15, 16 & 17 have FPS errors.
  • Lines that look fine: 2, 3, 4, 5 & 6.

Probably best to manually determine a suitable FPS value (can be changed in the Fenix header files grep *hdr -e 'fps =').
Lines 1 & 13 have FPS values of 79.000.
All other lines have values of 27.000.
Perhaps it is worth see if FPS values of 27.000 works well with lines 1 & 13 (two of the three immediately visible FPS errors).
Also note that if a line is split (e.g lines 1 & 13), all parts should have the same SCT values.

Hyperspectral Process
I have changed the FPS of lines 1 & 13 from 79.000 to 27.000 and processed all lines.
The new FPS for lines 1 & 13 is clearly worse. However, the reprocessed lines 14, 15, 16 & 17 also show significant SCT (and/or possible FPS errors).
Will continue to investigate.

Hyperspectral Delivery Check

Started.

comment:17 Changed 5 years ago by asm

Hyperspectral Delivery Check

-Replaced the hyperspectral data quality report with the latest one up to date.
-Renamed ".bil.jpg" screneshots to ".jpg"
-APL commands run without problems showing good overlaps (fine combination of SCT and FPS)
-All xml files have been updated to NCEO references
-Vegetation spectra shape matches 6S, only low levels in SWIR

I will start zipping files now.

Hyperspectral Delivery Check

Mapped files have been zipped just fine. Marking this project as ready to be delivered.
