IMAGE2000 was produced from ETM+ Landsat 7 satellite data and provides a consistent European coverage of individual orthorectified scenes in national map projection systems. The year 2000 was targeted as reference year, but a deviation of maximum 1-year was allowed to obtain a full coverage of Europe, which involves approximately 450 Landsat TM Frames. Where Landsat 7 data were not available, Landsat 5 data have been used instead. The spatial resolution is 25 metres for multispectral and 12.5 metres for panchromatic imagery SDI Unit, Institute for Environment & Sustainability, Joint Research Centre image2000@jrc.it custodian Land cover GEOSS DSTF 2011-01-17 publication geossNonCommercial otherRestrictions no limitations 25 eng imageryBaseMapsEarthCover -71.69318638360483 104.08802554326871 -1.1885656713426045 76.40313978448314 http://image2000.jrc.it dataset Conformity_001 INSPIRE testing 2011-01-21 creation See the referenced specification false Product 1 scenes correspond to the path/row of the Landsat orbit. All Image2000 product 1 scenes are ortho-corrected. The ortho-correction method consisted of using a physical model of the satellite's flight during the scene acquisition, which was then complemented with Ground Control Points (GCP's) and a Digital Elevation Model (DEM). Map projection information is attached to the model. The resulting product has excellent accuracy between the spectral bands, sub-pixel location accuracy throughout the image and excellent preservation of radiometric characteristics. The geometric correction was done on a Country basis - according to the relevant national map projection system(s). A rigorous orbital model was used. Control point measurements were used in a weighted least squares adjustment to estimate optimal values for the orbital and attitude parameters. The adjusted parameters were used to resample the raw scene by cubic convolution in a single step, instead of the usual two step procedure of first producing a system-corrected scene and then resampling a second time, thus causing unnecessary smoothing of the data. The final pixel size after resampling is 12.5m for the panchromatic band, 25m for the multispectral bands and 60m for the thermal band. All the orthorectified scenes are well within the requirement of Root Mean Square Error (RMSE)
