Info

The image below is a 10m pan sharpened subset using bands EO-1 ALI bands3, 4, 5 and the panchromatic band and the standard HSI pan sharpeningalgorithm with non-linear histogram matching. Forty Laplacian interpolationiterations were used. The band files were pre-processed using thePANCROMA TM HOT haze reduction algorithm.A few words about this impressive image. At 10m resolution it is 50% better thanthe corresponding Landsat image as the EO-1 platform has a 10m panchromaticband. In addition, the spectral fidelity is excellent because the spectral range ofthe EO-1 panchromatic sensor more closely matches the visible spectrum thanthe Landsat panchromatic band. This is what Landsat 8 should have been.Unfortunately, its panchromatic band, after ten years of development, will be nobetter than that of Landsat 7 launched in the 1990s.103
38. Working with Digital Globe® Data________________________________________________________________Digital Globe is a leading commercial provider of satellite imagery. Theirproducts are offered in a variety of resolutions and GeoTiff file format variants.Sample files are offered for download at the Digital Globe pages athttp://www.digitalglobe.com/product-samples. These products include theWorldView 1, WorldView2, and Quickbird brand names. The various productsare offered in both 8-bits and 11-bits per pixel images; unbundled and 3, 4 and 8file bundles using separate planar configurations in Big Endian byte order.PANCROMA TM can read all of the files offered for download on the Digital Globesample image download site. There may be additional configurations not offeredon the download page that PANCROMA TM cannot read. If you happen toencounter one, please contact us and we will try to accommodate your needs.Digital Globe offers multispectral VNIR band data and panchromatic files suitablefor pan sharpening. These are offered as two GeoTiff file sets. One file containsonly the panchromatic band with a resolution typically four times that of themultispectral bands. The multispectral bands are all in a single file, either writtenas separate bit planes or interleaved. In order to use the multispectral bands,you must first extract them from the bundled GeoTiff file and save them asindividual band files. Once they are extracted they can be handled exactly asLandsat or SPOT® files.WorldView2 ImageryIn order to perform the extraction, select ‘File’|’Open’. Then select ‘DecomposeBundles’. PANCROMA TM will detect whether the input file contains either a fourfile or an eight file bundle. If four file, the ‘Decompose Four File Digital GlobeBundle’ menu selection will be enabled. If eight file, the ‘Decompose Eight FileDigital Globe Bundle’ menu selection will be enabled. Once you select one orthe other, you will be prompted via a Save Dialog box to enter an output filename. A numerical suffix will be added to whatever name you select, for104
