iBEAM

• Next generation of AATSR-MERIS Toolbox– July 2005 – June 2007

• Features– Synergistic use of MERIS, AATSR and data of other

sensors using advanced co-registration functions – Development of additional EO data processors for MERIS

and AATSR– Access to OGC/ISO-conformant web services – Full support of the AVNIR 2 sensor onboard the Japanese

ALOS satellite– 3D visualisation of EO data– Data format review

• User support– Community support– 3 Training courses

BROCKMANN CONSULT


Manual Co-registration

• Keeping satellite coordinate system of reference image

• Ground control points (GPS)

• Non-rigid polynomial warping

• Different interpolation methods

• Quality report of resulting coregistration

BROCKMANN CONSULT


Automatic Image Registration

• 3 steps of AIR– Feature extraction

• Grey level based edge gradient magnitudes, Laplacian, Roberts Cross or Sobel operators

– Transformation• rigid, affine, non-rigid or (Q-shift complex) wavelet

transformations– Similarity metric

• mean squared difference (MSD), normalised cross-correlation (NCC) or mutual information (MI) and others

• UI:– Select bands and post-processing filter for similarity

metric– define the interpolation method for the re-sampling– display the transformation parameters and the statistics

of the similarity measure (min./max. deviation, RMSE)

BROCKMANN CONSULT


Online Data Access

• OGC: internet-based geospatial data services– Raster Data: Web Mapping Server (WMS)– Vector Data: Web Feature Server (WFS)

• Direct access from BEAM to WMS and WFS– Configuration of access to suitable WMSs and WFSs– Description of geospatial data layers of the WMS/WFS– Download, re-project and display the selected geospatial

data in a separate VISAT display layer, e.g. an image or vector shape overlay

BROCKMANN CONSULT


Software Redesign

• Development of a Java framework for the definition of generic EO data processing chains

• Redesign of the VISAT display framework in order to realize fast multi-layer views of raster and geo-spatial vector data

• Redesign of the VISAT plug-in framework in order to realize a plug-in management with on-line updates
