NASA’s Commercial Satellite Data Acquisition (CSDA) Program announces the addition of imagery from Vantor to its Satellite Data Explorer (SDX) data access and discovery tool. The imagery, which was obtained by Vantor’s Legion satellites, comes from Vantor’s 125-plus petabyte imagery archive, which dates back to 1999. The imagery from this archive contains a mix of panchromatic (black/white) and color imagery (up to 18 multispectral bands) and offers global coverage of up to 30 cm resolution.
There are three types of imagery available from this archive in SDX:
System-Ready Level 1B DataThis data is idea for users who are looking to apply their own tools and models to fully process the data and extract the information that they need. It comes with all bands, full bit-depth, and requires further processing to be ready for deriving downstream analytics. This basic processing of this product offers an imagery product ready for custom orthorectification.View-Ready Level 2A DataThis processing level is intended for users who want to get straight to using the data to extract downstream analytical information. It provides a basis for deriving downstream analytics and has been orthorectified against a coarse digital elevation model (DEM). It comes with all bands and full bit depth.Map-Ready 3-DThis data product offers standardized and orthorectified (i.e., corrected to remove distortion caused by terrain variations, and sensor angle), imagery that has been radiometrically calibrated and geo-rectifi …
