Paper Abstract

The SPOT MTF is tested during the post-launch performance assessment using a photointerpretative method. To this end an image catalog is prepared before launch. This catalog is based on aerial high resolution photographs of 20 cities in the Southern part of France in the panchromatic band. Each photograph is subsequently digitized and sampled at a 10 meter resolution, and for each original photograph a series of 9 images with various and known MTF is obtained through parametric convolution. SPOT MTF is then estimated from a visual comparison between SPOT images and images from the reference catalog. Moreover an algorithm of evaluation of high spatial frequency content is applied to a set of suitable SPOT images, when the two HRV instruments are in parallel viewing, to allow direct comparison between the two instruments MTF in the panchromatic band. This paper presents a detailed description of these methods and their results.
