An orthophoto map results when gridlines, boundaries, place names, and marginal information are added or overprinted. Which map type does this describe?

• A. Photo Map
• B. Orthophoto Map
• C. Topographic Map
• D. Thematic Map

Answer: (B)

Orthophoto maps are created by taking a geometrically corrected aerial photograph and overprinting it with standard map elements such as gridlines, boundaries, place names, and marginal information. The orthorectification process removes distortions from terrain and sensor perspective so that distances and areas on the image correspond to true ground measurements. When you add the cartographic overlays, the image becomes a map product while preserving the realistic detail of the photo. This combination—a corrected photographic base plus map conventions like grids, labels, and marginal data—defines an orthophoto map. A photo map would rely primarily on a photograph as the base without necessarily achieving the same geometric accuracy. A topographic map emphasizes terrain representation like contours and elevations rather than a photographic base. A thematic map focuses on illustrating a specific theme (e.g., rainfall, land use) rather than the integration of an overprinted photograph with cartographic elements.
