Features may appear larger on an orthophoto map compared to a topographic map because orthophoto maps are created by overlaying images taken from an aerial perspective onto a map grid. This process can create a more realistic visual representation of the features on the ground, giving the impression that they are larger in size. In contrast, topographic maps are specifically designed to accurately represent the shape and elevation of the terrain, which can sometimes make features appear smaller in comparison. Additionally, the scaling and projection of the two types of maps can also contribute to differences in the perceived size of features.
