In Geo Engineering and Geo Informatics, the scale of aerial photographs is an important parameter that determines the level of detail visible in the images. Scales in aerial photography define the relationship between a distance on a photo and the actual distance on the ground.
For determining the range of medium scale aerial photographs, we need to know the general characteristics that define such scales. Medium scale aerial photographs typically feature a balance between detail and coverage, appropriate for analysis that requires moderate levels of detail.
Medium scale aerial photographs typically have scales between 1:15000 and 1:30000. These scales are effective for regional analysis and planning because they offer a good compromise between ground coverage and detail, allowing for sufficient detail of features like buildings, roads, and natural formations without the extensive detail provided in larger scale photographs.
Hence, the correct answer is the scale range: 1:15000 and 1:30000
