THEOS Multispectral (Level 1A/ 2A) Products
Listed in NASA Earthdata CMR
THEOS multispectral products provide 15 meter resolution (at nadir) and 8 bits information depth.
Description
All four bands are delivered as one file. The output scene is a square scene of 90 km. x 90 km.
Level 1A - The image data is provided with radiometric correction of non‐uniformities of the detectors of the imaging system. This product is intended for users who will perform their own geometric correction processing. Level 2A - In addition to radiometric correction, this product has geometric correction of systematic effects (panoramic effect, Earth curvature and rotation).

Internal distortions of the image are corrected for the imagery to be useful in measuring distances, angles, and surface areas. The imagery is projected to a standard cartographic projection (UTM WGS84 bydefault) using a terrain model but without ground control points.
