What term describes several air photos mounted together to form a continuous picture of a large area?

• A. Pantograph
• B. Map Compilation
• C. Series Maps
• D. Mosaic

Answer: (D)

When you take several overlapping air photos and join them to create one continuous picture of a large area, you’re making a mosaic. This process stitches the individual photos together, aligning shared features and blending edges so the final image reads as a single, seamless landscape. A mosaic is especially useful for broad-area mapping and analysis because it removes the visible seams between photos and provides a coherent base image for measurements and planning. The other terms don’t describe this stitched, seamless result: pantograph is a device for copying or scaling drawings, map compilation refers to gathering maps into a collection rather than creating a single composite image, and series maps are maps published in a sequence or set rather than a stitched panorama.
