Introduction Maxar owns and operates the most agile and sophisticated constellation of high-resolution, high-accuracy Earth imaging satellites. Accuracy testing is performed on a regular basis by comparing images to highly accurate ground control points. This paper discusses the process that is used to assess accuracy and the resulting accuracy statements for WorldView-1 and WorldView-2 satellite products. Maxar offers a range of imagery products with a variety of processing, radiometric correction and geometric enhancement options, which result in differing levels of accuracy. The product levels are summarized in Table 1.
