Description (last modified by knpa)

Data location: ~arsf/arsf_data/2010/flight_data/western_europe/EUFAR10_03-2010_196_Lisbon

Data arrived from ARSF via network transfer on 2nd/08/2010.

Scientific objectives:
Objective 1.- Development of a reliable tool to estimate coastal water quality indicators by using remote sensing
techniques, both airborne and satellite.
1.1. | Development of a set of semi-empirical algorithms based on hyper-spectral airborne and in-situ data for
estimating the concentrations of the water constituents;
1.2. | Migration of the developed algorithms into the satellite workflow.

Priority: a4h

PI:Castillo-Lopez

Sensors:

  • Eagle
  • Hawk
  • Leica LIDAR
  • RCD Camera (16/09/10)

Starting navigation processing.

comment:3 Changed 12 years ago by jb362

IPAS navigation processing done.

comment:4 Changed 12 years ago by ella

Waiting for logsheet.

Applanix processing was problematic because the flight was 100km away from the nearest base station.
POSproc failed to create an Sbet file.

Starting camera processing.

Starting LiDAR processing

There are six LiDAR lines for this project.

Lines 1 and 2 are very short, contain very little data (approx 30% first returns) and are very noisy. From the leica flightline log it it looks like there was also an issue with the range correction during the capture of these lines.

Lines 3 and 4 contain no useful data.

Line 5 is partially over water and contains a 90 degree turn.

Line 6 consists of four distinct lines, including the turns in between (see attached screenshot). This may need to be separated into 4 lines.

There is little overlap between lines (just the cross of Line 6 with itself) which will make correcting for roll difficult.

Going to wait until next week when ARSF Ops return and we can get the logsheet before proceeding any further with this project.

Started camera processing for this project but in the kml file it's very hard to see which images will be needed and which won't. This is because it the camera wasn't turned off between flight lines. This processing will therefore be held until we have the logsheet for this project. If I have left before we do get the logsheet iopa will be picking up the camera processing.

Also, all the .tif files for the camera processing have already been created.

Call from Phil to say there are still looking for the logs sheets for this project as well as for Lisbon flight day 197

Both projects were flown on an ad hoc basis. They were unable to turn the LiDAR off during the flight as they were flying over water but the hyperspectral was switched off between lines to conserve disk space. As a result there will not be a match between the eagle/hawk and the LiDAR lines.

Logsheet has arrived and been saved in ~arsf/arsf_data/2010/flight_data/archive-overflow/EUFAR10_03-2010_196_Lisbon/admin

Iopa will be taking over this camera project.

comment:13 Changed 12 years ago by ella

Starting camera delivery check.

comment:14 Changed 12 years ago by ella

Camera check complete.
Two photos have been removed and the read_me and kml file have been updated.
Ready to deliver.

RCD camera was dispatched today, 16th September 2010.

  • Owner set to knpa
  • Status changed from new to assigned

Taking over hyper-spectral processing for this project.

comment:17 Changed 12 years ago by knpa

Issue with applanix - raw data in two parts with a gap in the middle. This gap covers one of the lines (Gen3).

Also, cannot find eagle data for first two lines (Gen 1/2) and (Gen 3).
