Image Mosaicking

Image mosaicking is the process of stitching together multiple georeferenced images into one seamless, continuous composite image that covers a larger geographic extent. Individual satellite scenes or aerial photographs typically cover limited areas, so mosaicking is essential for creating wall-to-wall basemaps, regional orthophotos, and cloud-free composite imagery. Key processing stepsThe mosaicking workflow includes geometric alignment (ensuring all images share a common coordinate system and projection), radiometric balancing (adjusting brightness and color across images to create visual consistency), seamline generation (computing optimal boundaries between overlapping images to minimize visible seams), and blending (smoothing transitions along seamlines). Cloud-free composites select the best available pixel from multiple acquisitions to eliminate cloud contamination. ApplicationsImage mosaics serve as basemaps for GISGISGeographic Information Systems (GIS) enable users to analyze and visualize spatial data to uncover patterns, relation... analysis, provide continuous visual context for planning and design, support regional land cover mapping, and create cloud-free reference imagery. Drone survey workflows routinely generate orthomosaics from hundreds of individual photographs using photogrammetric software.
