Abstract: Products derived from MSG/SEVIRI and Spot/VEGETATION are routinely provided to a large audience of users, i.a. through the EumetCast broadcasting system. Although MSG/SEVIRI has a significantly coarser resolution than Spot/VEGETATION, its thermal channels and higher rate of observation (every 15 minutes) extends the information extracted from Spot/VEGETATION images (1km resolution). MSG/SEVIRI being a geostationary satellite and Spot/VEGETATION a polar orbiting system, the combination of both sources of information requires to re-project the images in a unique cartographic system. This document shows how to project MSG images onto the Spot/VEGETATION grid, in a WGS84 plate carrée representation. The document also analyses the image distortion of the geostationary image and of its reprojection. The results have a sufficient geometric quality to allow the combination of re-projected MSG images with Spot/VEGETATION S10 products.
