WorldView-4 Full Archive

WorldView-4 high resolution optical products are available as part of the Maxar Standard Satellite Imagery products from the QuickBird, WorldView-1/-2/-3/4, and GeoEye-1 satellites. All details about the data provision, data access conditions and quota assignment procedure are described into the Terms of Applicability available in Resources section. In particular, WorldView-4 offers archive panchromatic products up to 0.31 m GSD resolution, and 4-Bands Multispectral products up to 1.24 m GSD resolution. Band Combination Data Processing Level Resolution Panchromatic and 4-bands Standard (2A) / View Ready Standard (OR2A) 15 cm HD, 30 cm HD, 30 cm, 40 cm, 50/60 cm View Ready stereo 30 cm, 40 cm, 50/60 cm Map Ready (Ortho) 1:12.000 Orthorectified 15 cm HD, 30 cm HD, 30 cm, 40 cm, 50/60 cm The options for 4-Bands are the following: 4-Band Multispectral (BLUE, GREEN, RED, NIR1) 4-Band Pan-sharpened (BLUE, GREEN, RED, NIR1) 4-Band Bundle (PAN, BLUE, GREEN, RED, NIR1) 3-Bands Natural Colour (pan-sharpened BLUE, GREEN, RED) 3-Band Colored Infrared (pan-sharpened GREEN, RED, NIR1) Native 30 cm and 50/60 cm resolution products are processed with MAXAR HD Technology to generate respectively the 15 cm HD and 30 cm HD products: the initial special resolution (GSD) is unchanged but the HD technique increases the number of pixels and improves the visual clarity achieving aesthetically refined imagery with precise edges and well-reconstructed details.

Vision-1 full archive and tasking

Vision-1 provides very high resolution optical products, with 87cm resolution in Panchromatic mode and 3.48m in Multispectral Mode. Products are in DIMAP format; the image is in GeoTiff format with 16 bit encoding; the applied geographical projection is WGS84 UTM. Spectral band combination options: Panchromatic (PAN): includes data contained within a single high resolution black and white band, with product pixel size of 0.87m Multispectral (MS4): includes four multispectral (colour) bands: Blue, Green, Red and Near Infrared. The product pixel size is 3.48m Bundle (BUN): provides both the 4-band multispectral, and the panchromatic data from the same acquisition in a single, non-merged product. Data is provided as 16-bit GeoTiffs with pixel sizes of 3.48m and 0.87m for MS and PAN data respectively Pansharpened (PSH): single higher resolution 0.87 colour product obtained by the combination of the visual coloured information of the multispectral data with the details provided in the panchromatic data. Two different geometric processing levels are: Projected (level 2): The product is mapped onto the Earth cartographic system using a standard reference datum and projection system at a constant terrestrial altitude, relative to the reference ellipsoid. By default, the map projection system is WGS84/UTM. The image is georeferenced without the application of a Digital Elevation Model (DEM) and supplied with the RPC model file. Pansharpened are not available as projected product Standard Ortho (level 3): georeferenced image in Earth geometry, including the application of a Airbus World DEM for Ortho and GCPs (using Airbus Intelligence One Atlas BaseMap as reference). The orthorectification procedure eliminates the perspective effect on the ground (excluding buildings) to restore the geometry of a vertical shot. Only the basic radiometric processing is available providing the radiance value. As per ESA policy, very high-resolution imagery of conflict areas cannot be provided.

Visible Channel Long Term Drift Analysis Using Desert Targets

Visible Channel Long Term Drift Analysis Using Desert Targets. The stability of AATSR visible channel calibrations have been measured using data from stable desert targets. The calibration drift rates obtained from the time-series are less than 3.5% per year and comparable to those measured for ATSR-2. Application of the drift correction to AATSR L1B images is discussed.
