An orthophoto is a geometrically corrected aerial or satellite image that represents the Earth's surface with uniform scale. It is used in GIS, urban planning, and land management. Orthophotos are created by correcting distortions due to terrain, sensor tilt, and perspective, ensuring accurate measurements.
Mosaicing is the process of stitching multiple aerial images into a single seamless image. It is essential for creating large-scale maps and orthophoto datasets. Mosaicing ensures high-resolution, distortion-free imagery, which is useful for agriculture, construction, and environmental monitoring.
