EAS 324 Midterm - key 1. Small scale: little detail, more regional coverage, large representative fraction number (ex. 1:50,000); useful for broader overview of units Large scale: good and high degree of detail, smaller areal extent, small representative fraction number (ex. 1:2,000); very useful for land surveying in cities, tree or plant identification, etc. Marking: 2 marks for examples, remaining 3 marks for explanation 2. a) If area indicated was too small or too large lost ½ mark b) Area directly below (or close to it) the aircraft and so there is less distortion of the boundaries since vertical exaggeration is decreased relief is more representative. This is good when looking at macroscale features, but may actually be a disadvantage when looking at microscale ones. (Note: as focal length decreases, vertical exaggeration increases) c) As overlap amount increases, vertical exaggeration decreases so relief is less pronounced. 3. Any good disadvantage was accepted. One mark for each one. A few examples:
