Orthomosaikkers

Orthomosaikkers are not a recognized term in photogrammetry or remote sensing. It is possible this is a misspelling or a portmanteau of existing terms. If the intention was to refer to orthomosaics, an orthomosaic is a geometrically corrected image mosaic. It is a type of raster image produced by stitching together multiple aerial photographs or satellite images. Unlike a standard mosaic, an orthomosaic has been geometrically corrected, or orthorectified, to remove distortions caused by camera tilt, lens aberrations, and terrain relief. This process ensures that the scale of the imagery is uniform throughout, allowing for accurate measurements and analysis.

Orthomosaics are created by combining numerous overlapping aerial images. Software uses ground control points (GCPs) or a digital elevation model (DEM) to align and rectify these images. The overlapping areas allow the software to create a seamless and accurate representation of the ground. The resulting orthomosaic presents a top-down view that is georeferenced, meaning it can be accurately overlaid with other geographic data. They are widely used in various fields, including surveying, mapping, precision agriculture, urban planning, and environmental monitoring, due to their visual realism and geometric accuracy.
