[ Get Data ]

Abstract: THEOS imagery products are available in a 4-band pan-sharpened product option. These products combine the visual information of 4 multispectral bands (blue, green, red, Near IR), with the spatial information of the panchromatic band. Pan-Sharpened products are available as product option for level 2A only. The output scene is a square scene of 22 km. x 22 km.

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.
