Comparisons of coincident SCA maps derived from different sensors

The table below lists all possible comparisons of  SCA maps derived from coincident EO data from different sensors (HROI, MROI and SAR) and indicates which HydAlp basins each comparison is being conducted in. For further details on a comparison being conducted within a particular basin click on the  name of the basin.

BASAT: comparisons of coincident SCA maps derived from different sensors Listed below are all the comparisons being conducted within BASAT of SCA maps derived from coincident EO data from different sensors. Click on any one image date to get further details about the image and its status of analysis.

HROI/MROI

Landsat TM 8/6/96 and NOAA AVHRR 8/6/96
Landsat TM 8/4/97 and NOAA AVHRR 8/4/97
Landsat TM 19/5/97 and NOAA AVHRR 19/5/97
Landsat TM 15/9/97 and NOAA AVHRR 15/9/97
Landsat TM 13/5/98 and IRS-1C WiFS 13/5/98 Currently no imaging model is available for geocoding the WiFS data.

The SCA maps derived from each of the above coincident datasets have yet to be compared.

HROI/SAR

Landsat TM 19/5/97 and ERS SAR 12/5/97 For results see (link to IGARSS'98 paper on HydAlp WWW page).
Landsat TM 13/5/98 and Radarsat 11/5/98 For results see (link to ADRO and ESTEC papers on HydAlp WWW page).

MROI/SAR

TN will any work be done on this?

SAR/SAR

The amount of missing coverage occurring in ERS and Radarsat (S7) images is compared in (link to ADRO and ESTEC papers on HydAlp WWW page). A quantitative comparison is still required of the wet SCA maps derived from coincident ERS and Radarsat SAR images.

BASCH: comparisons of coincident SCA maps derived from different sensors Listed below are all the comparisons being conducted within BASCH of SCA maps derived from coincident EO data from different sensors. Only MROI data is being analysed in BASCH. Click on any one image date to get further details about the image and its status of analysis.

MROI/MROI

NOAA AVHRR 30/5/96 and RESURS 29/5/96
NOAA AVHRR 14/6/96 and RESURS 15/6/96
NOAA AVHRR 23/7/96 and RESURS 20/7/96

So far the the SCA maps derived from these coincident images have only been compared on a visual basis. They showed good agreement both in geometric and classification terms. A quantitative comparison is still required.

BASSW: comparisons of  SCA maps derived from different sensors Listed below are all the comparisons being conducted within BASSW of SCA maps derived from coincident EO data from different sensors. Click on any one image date to get further details about the image and its status of analysis.

HROI/MROI

IRS-1C LISS-III 25/6/96 and NOAA AVHRR 25/6/96

Maps of SCA derived from these datasets have yet to be compared.
Classifications of the HROI images will be used to verify the AVHRR classifications.

HROI/SAR

Landsat TM 25/6/92 and ERS SAR 23/6/92
Landsat TM 4/6/96 and ERS SAR 5/6/96

Maps of SCA derived from these datasets have yet to be compared.
Classifications of the HROI images will be used to verify the SAR classifications.

MROI/SAR

NOAA AVHRR 22/5/92 and ERS SAR 19/5/92 (Possibly too early in the melt season to be of real interest).
NOAA AVHRR 19/6/92 and ERS SAR 16/6/92
NOAA AVHRR 25/6/92 and ERS SAR 23/6/92
NOAA AVHRR 4/6/96 and ERS SAR 5/6/96

Further coincident NOAA AVHRR and ERS SAR image pairs should be available from 1998.
Maps of SCA derived from these datasets have yet to be compared.

EO data and status of analysis Listed below are all the EO data being analysed in each of the HydAlp test basins (currently mainly just images used for SCA comparisons are listed). Click on the Path/row or Track/frame number to get further details about each image (this has yet to be implemented). The status of analysis of each image is indicated under three headings: acquired/geocoded/classified. Where an image has been acquired the name of the HydAlp partner holding the raw data is indicated, a N indicates that the image is available but still has to be acquired, a ? indicates that the image is available but a final decision is still needed on whether to acquire it or not.
