What is an image mosaic in the context of remote sensing?

An image mosaic in the context of remote sensing refers to a composite image created from multiple photos or satellite images. This process involves stitching together several individual images to create a continuous, seamless view of a particular area. This technique is essential in remote sensing as it allows for a comprehensive representation of larger landscapes that cannot be captured in a single image due to limitations in satellite resolution, coverage, or the need to cover extensive geographical areas.

Mosaics are particularly useful in applications such as environmental monitoring, land use planning, and disaster response, as they provide detailed and informative visualizations that help in analysis and decision-making. The process of creating a mosaic involves aligning and integrating the overlapping images, correcting for differences in brightness and color, and sometimes applying geographic corrections to ensure that the final product accurately represents the area being studied.
