Recent remote sensing applications play more and more important roles in many fields such as
environmental monitoring, disaster assessment or creating base map for land use land cover.
Therefore, the analyzing remote sensing is moving from single image scene to regional
which require several image scenes. However, the quality of mosaic image depends on the
radiometric and geometric characteristics of individual image. Understanding that, with
requirements of this techniques, EOFactory provide a mosaic tool to merge many satellite or
aerial images together.
