Answer:
I hope this helps!
Explanation:
The topographic map is a smaller scale map so everything is shown in more detail whereas an orthophoto map is a larger scale map and only certain things are shown.
Answer:
orthophoto: picture (corrected for viewpoint artifacts)
topo map: representational drawing (with contour lines)
Explanation:
An orthophoto is a pictorial representation of an area of the Earth; a topographic map is a drawing that uses colors, lines, and shapes to represent an area of the Earth.
An orthophoto is a photographic image of a portion of the Earth's surface that has been corrected to remove any artifacts of the viewpoint from which the photo was taken. Objects with a vertical aspect will have their appearance adjusted so they are presented on the orthophoto as though viewed from above.
In addition, its scale has been corrected so that measurements of distance made on one part of the orthophoto will have the same scale as those made on any other part.
An orthophoto may or may not have contour lines added.
A topographic map is a drawing that represents the terrain of a portion of the Earth's surface. It does so using colors, shapes, and shading, along with contour lines. It generally will show place names, political boundaries, and other features that may not show up in a photograph.
As nearly as possible for its size and scale, it will be drawn so that distance measurements made on one part of the map will have the same scale as those on any other part.

Additional comment
Orthophotos have been created from photographic images taken from an airplane. From such a platform, any objects not directly under the plane will have an appearance that includes a side view. The object's location in the photograph will depend on the altitude of the plane and the height and distance of the object relative to the flight path.
Current technology allows photographic images of the Earth's surface to be taken from satellites at a much higher altitude. The adjustments required on such images tend to be smaller, as the viewpoint and elevation-related aberrations are nearly non-existent.
