Standard Imagery products are suitable for users requiring modest   absolute accuracy and/or large area coverage. Users of Standard Imagery products usually possess sufficient image processing tools and knowledge to manipulate and exploit the imagery for a wide variety of applications.Standard Imagery products are radiometrically corrected, sensor corrected, geometrically corrected, and mapped to a cartographic projection. Standard Imagery products are available as black & white, color, or pan-sharpened with a 60-centimeter or 70-centimeter GSD, or multispectral with a 2.4-meter or 2.8-meter GSD. All Standard Imagery products have uniform pixel spacing throughout the entire product.The radiometric corrections applied to this product include: relative radiometric response between detectors, non-responsive detector fill, and a conversion for absolute radiometry. The sensor corrections account for internal detector geometry, optical distortion, scan distortion, any line-rate variations, and registration of the panchromatic and multispectral bands. Geometric corrections remove spacecraft orbit position and attitude uncertainty, Earth rotation and curvature, and panoramic distortion.

Accuracies: Ortho Ready Standard Imagery products have a delivered absolute geolocation accuracy of 23-meter CE90%, excluding any topographic displacement and off-nadir viewing angle. When processed using supplied RPCs, a high quality DEM (e.g. DTED Level 2), and submeter GCPs, accuracies in the range of 3 to 10 meters RMSE may be achieved.With the exception of lack of terrain correction, Ortho Ready Standard Imagery products have all the same specifications as Standard Imagery products. All the specifications in this section apply to both Standard Imagery products and Ortho Ready Standard Imagery products. Please see section 5.3 for more detail and comparisons between Basic Imagery products, Standard Imagery products, and Ortho Ready Standard Imagery products.
If the order polygon crosses more than one scene, each scene will be processed individually. As the Standard Product is not mosaiced, one image file will be delivered for each scene the order polygon intersects.
